Unique oilless brass bushing -solutions. Oilless Brass Bushing – Things To Know.

What is an oilless brass bushing? The role of oilless bronze bushings in machines is to reduce friction, reduce vibration, prevent corrosion, reduce noise, facilitate maintenance, and simplify the structural manufacturing process. In moving parts, the parts will be worn out due to long-term friction, and this is when bronze bushings are used to reduce friction. If the oil less bronze bushings wear to a certain point, only the oil less bronze bushings need to be replaced, thus saving the cost of replacing the shaft or seat.

Oil less bronze bushings also play a bearing role, belongs to the large category of sliding bearings, is a bearing that works under sliding friction, relative to the shaft is rotating, generally need to assist there is a lubrication system work. Sliding bearings work smoothly, reliably and without noise. In the liquid lubrication conditions, the sliding surface is lubricant separation without direct contact, but also can greatly reduce the friction loss and surface wear, the oil film also has a certain vibration absorption capacity role is lubrication, heat dissipation, friction reduction, extend life, etc.

Oil less brass bushings characteristics.

1, wear resistance: the wear resistance of oil less bronze bearing is still relatively good, different materials have different characteristics of the equipment. Oil less bronze bushings parts internal organization is still relatively tight, will not appear too loose phenomenon, it is no porous trachoma, so from the appearance of the Oil less brass bearings still looks brighter, its color is more special. And the most important thing is that its hardness is relatively high. 2.

2. Corrosion: Another feature of oil less brass bushings is corrosion resistance and good corrosion performance. It is mainly used in the atmosphere and fresh water, because this environment is relatively good. In the process of using oil less bronze bushings, it is generally not easy to bite the situation. The corrosion resistance of Oil less bronze bushings is mainly reflected in some chemical elements, such as: dilute sulfuric acid, hydrochloric acid and fatty acids and other elements, so that the corrosion resistance of bronze bushing is very good, the reason why it does not appear to bite the situation is mainly due to its own characteristics, its performance is relatively good, even in the absence of lubricants and water lubricants can still carry out normal work, in Sliding and self-lubricating performance can still be maintained.

3. pressure resistance: Oil less bronze bushings pressure resistance is also relatively good, its surface pressure is very large, can well withstand the bearing side pressure, in the case of high load pressure Oil less brass bushings can also be operated, suitable for low-speed heavy load occasions.

Oil less bronze bushings bearings processing technology: sand casting, metal casting, centrifugal casting, precision casting, pressure casting, vacuum casting

Oilless Bearing Features

1. No need for oil supply device, oil injection hole, oil tank processing

The cost of oil supply device, processing fee, assembly fee and other extra costs and time savings can significantly reduce manufacturing costs.

2、Reduction of operation cost

The amount of lubricant used and the maintenance cost of the equipment are greatly reduced, and the risk of insufficient oil supply is eliminated.

3.Reduction of design time

In addition, the use of self-lubricating bearings can also improve mechanical performance, extend the service life and improve reliability, etc. to obtain significant results.

4. Lubricant recovery and environmental protection

No need to recycle waste oil, which is conducive to environmental protection. JDB(500#SP) self-lubricating bearing as mechanical industry parts, there is a certain broad sense of use. In order to make the mechanical transmission run properly, a lot of efforts have been made. The bearings are distinguished into rolling bearings and sliding bearings. The general sliding bearing will cause hair pulling under high load movement mode, foreign matter mixing, temperature condition, oil supply, imperfect maintenance and so on. Like this general sliding bearing can not use the harsh conditions, solid inlay type metal self-lubricating bearing wear resistance, hair pulling resistance on, play the performance of the bearing should be, to achieve high performance of machinery and maintenance-free role.

Precautions for use

1、When possible, try to use standard specifications when designing.

2、Please pay attention to the presence of foreign matter on the surface when assembling.

3. If the surface of the sliding surface is black or gray-black due to the oil film formed by the solid lubricant after use, please do not scrub it and use it as usual.

4、Before assembly, if the lubricant is applied to the wear parts, it can shorten the period of integration and facilitate the operation and operation of the machine.

5. assembly should be slowly pressed into, strictly forbidden to knock, so as not to damage the bearing and cause deformation.

6. design, different parts should be selected with the appropriate material, in order to improve the mechanical properties and extend the service life of the bearing.

7. in high load bearing, reciprocating motion, it is recommended to use screws to fix.

8. In fresh water, seawater and offshore operations, it is recommended to use stainless steel or surface chrome plating for the grinding shaft.

Oilless Bushing Product advantages.

1. flexible, simple and convenient design and wide range of use.

Oil supply system in the mechanical design is a labor-intensive, time-consuming device, the use of solid self-lubricating bearings in the design does not need to consider the refueling device, saving the refueling device equipment, and can be designed for a variety of special occasions, the solid self-lubricating bearings into a variety of shapes to meet the needs of a variety of special occasions, the use of solid self-lubricating bearings, can significantly reduce mechanical maintenance, oil and other costs.

2. no oil can be used.

Because the linear expansion coefficient of solid self-lubricating bearing is larger than the metal matrix, so when the solid self-lubricating bearing starts to run, the oil film will be transferred to the wear parts and realize self-lubrication, so the solid self-lubricating bearing can be used in the place where it is difficult to add oil and can’t add oil or grease, even in the case of low speed and high load, it can play a good lubricating role.

3. low cost of use.

Traditional mechanical design, in a certain operating time, to often refueling maintenance, check the oil table, oil supply device is smooth, due to regular refueling led to the body itself and the surrounding environment pollution, resulting in increased maintenance costs, the realization of self-lubrication, not only can achieve a neat environment, and greatly reduce the cost of using lubricants.

4. superior performance under high load carrying and low speed conditions.

Solid self-lubricating bushing bearing is made of centrifugal casting of high-strength alloy brass as substrate, which plays the role of load bearing, and the special formula of graphite with good self-lubricating performance as lubricant, which plays the role of self-lubrication, so it integrates their respective advantages, and can play a superior performance even under high load plain bearing and low speed situation.

5. it can play superior wear resistance in places where oil film formation is difficult such as reciprocating motion, rocking motion and frequent starting and stopping.

The arrangement principle of solid self-lubricating bushing bearing lubricant is to ensure that the lubricant acts on all parts of the grinding parts during operation, so the arrangement of the lubricant must be determined according to the direction of movement of the grinding parts to determine the location of the lubricant arrangement.

6. superior chemical resistance and corrosion resistance.

The lubricant of solid self-lubricating bronze bearing is made of special formula of graphite, PTFE, molybdenum disulfide and other wear-resistant materials, which has stable molecular structure, and the metal matrix can be selected according to different metals with different chemical resistance and corrosion resistance, so the solid self-lubricating cast bronze bearing has superior chemical resistance and corrosion resistance.

7. The cost of the product is more competitive, compared with similar products, the working life is longer, requiring little maintenance, long replacement cycle, good performance.

Self-Lubricating Components, Oilless Bushing Factory Direct Wholesale

Many of our self-Lubricating oilless components are self-lubricating. Self-lubricating parts are initially more expensive than conventional parts; however, they have the advantage of built-in permanent lubrication. No additional lubrication is ever required. In terms of total life cycle cost (i.e., taking into account the cost of periodic lubrication), self-lubricating parts are always less expensive than conventional parts-often quite low, because of the risk of not using lubrication.

Graphite Self-Lubricating Oilless Bushes

Graphite plugs provide self-lubrication. Graphite has some unusual properties that make it an excellent lubricant. Chemically, it is one of the three common isomers of carbon (amorphous carbon and diamond are the other two). In contrast to diamond, which has a very dense and strong three-dimensional crystal structure, graphite has a two-dimensional crystal structure – strong in two dimensions, but weak in the third. Its atoms are arranged in parallel sheets that can be easily sheared off, which gives graphite its characteristic slipperiness. For example, if you rub a pencil lead with your fingertip, it will feel greasy. This sensation is the sliding and flaking of the crystal flakes.

It is these sheared off crystal flakes that provide the lubrication during the self-lubrication process, sort of like a piece of tissue paper between two pieces of glass. Initially there is no lubrication, but as the two mating surfaces (e.g., bushings and shafts) move against each other, trace amounts of graphite are distributed across the wear surface and function as a solid lubricant. Because of its excellent stability, graphite will stay there for a long time. While graphite will sublimate at 10,000 degrees Fahrenheit in a reducing environment, it will oxidize in air at about 500 degrees Fahrenheit, so it is important to keep the temperature well below this threshold. In addition, the coefficient of thermal expansion of graphite is almost zero. When a graphite plug is embedded in a metal part, the metal will expand, but the graphite plug will not. The plug will loosen, and if the plug has any open surface (i.e., not limited by the mating part), then the temperature range will be limited to about 200 degrees Fahrenheit.

Additional lubrication of Self-Lubricating oilless parts with graphite

In general, we do not recommend this. The only exception is when new parts are fitted together and several cycles are required to distribute the graphite over the wear surface. Some customers have found it useful to rub a little light oil (never grease) on the wear surface, which can be used as a temporary lubricant until the self-lubricating action begins. Beyond that, any additional lubrication is actually detrimental to the graphitized part. Liquid lubricants tend to attract dust and grit, leading to premature wear of the graphite. Grease is a particular problem; graphite shaft bearing bushing parts should never be lubricated.
