VDI guide element – self lubricating bearing bushing graphite brass
A self-lubricating bearing bushing is a type of bearing that is designed to operate without the need for additional lubrication, such as oil or grease. This is achieved by incorporating a solid lubricant, such as graphite, into the material of the bushing.
Brass is a common material used for self-lubricating bearing bushings because it is strong, durable, and has good wear resistance. The addition of graphite to the brass further enhances its self-lubricating properties, providing a low-friction surface that reduces wear and minimizes the need for maintenance.
The VDI (Verein Deutscher Ingenieure) is a German organization for engineers, and the use of self-lubricating bearing bushings in VDI applications is common due to their reliability, long service life, and low maintenance requirements.
When selecting a self-lubricating bearing bushing for a VDI application, it is important to consider factors such as load capacity, operating temperature range, and compatibility with the surrounding environment. Proper installation and maintenance are also crucial to ensure the bearing operates effectively and safely over its service life.

In order to solve the lubrication problems of high temperature, low speed, heavy load, high dust, water washing, and shock vibration in mechanical equipment, oil-free self-lubricating bearings are selected. Self-Lubricating Guide Bushes – Mould & Die Solutions！
1. bearing structure self-lubricating bearing is a composite bearing, it is in the bearing matrix of the metal friction surface to form the appropriate size and order of the hole, the molybdenum disulfide, and graphite embedded in the metal sleeve on the composite self-lubricating slider, made of composite bearings. The solid lubricant has a friction area of 25%/65%. The solid self-wetting slider can work normally at 280℃. However, due to its low mechanical strength, weak load-bearing capacity, and easy deformation, it can be embedded in the metal groove to suppress this defect and form a metal part as a load-bearing force, while the self-lubricating block acts as a lubricating agent.
The lubrication mechanism of self-lubricating bearing is that in the sliding friction between the bushings, some self-lubricating material molecules are transferred to the metal surface of the shaft, filling the micro-uneven surface and forming a more stable solid lubricating film. The solid lubricating film is made to grind in between to prevent the shaft and sleeve from adhesive wear. This reasonable combination combines the complementary advantages of copper alloy and non-metallic anti-wear materials, especially suitable for oil-free, high temperature, high load, low speed, anti-fouling, corrosion resistance and strong radiation environment in the range of motion. As well as permeate in water or other solutions, in special working conditions simply can not be lubricated.
2. The specific surface area of the self-lubricating block is larger than the surface area of the self-lubricating block, which is related to the operating speed, bearing strength, low working speed, bearing strength, and metal occupying area. For example, the trolley walking wheel self-lubricating block self-lubricating block area of about 25%, the spindle mechanism rotating shaft bearing is fully lubricated, bearing strength is not large, self-lubricating block occupies an area of about 65%.
3, shaft tile material technical requirements: self-lubricating bearing bush made of alloy copper. The liner should have high hardness, the hardness shall not be less than HRC45.
Self-lubricating block geometric shape and structural requirements. The self-lubricating slider has two kinds of cylindrical and rectangular. Self-lubrication can use a cylindrical shape according to the size of the area, on the other hand, a rectangular shape can be used. Any shape must be firmly trimmed to prevent it from falling off during work.
5. The coefficient of linear expansion of a self-lubricating block with a clearance value between the bushing and the shaft is approximately 10 times that of steel. To accommodate changes in bearing temperature, the clearance between the shaft and bushing is 0.032-0.15 mm of the original metal part, increasing by 0.45-0.5 mm. the self-lubricating block protrudes 0.2-0.4 mm from the bushing metal on the side of the friction sub. This will produce sufficient lubrication and reduce power consumption during the initial grinding phase of bearing operation.
Types and selection of self-lubricating bearings.
Made of solid bronze with self-lubricating graphite, Guide Pin Bushings are available in all industry standard (metric and inch) sizes. Gas lubrication bearing is a kind of solid lubrication bearing, which is based on wear-resistant metal material, and it can reduce the friction coefficient by adding various lubricating materials to realize self-lubrication. With the development of industrial technology and the progress of science and technology, the performance and reliability of bearings are required more and more under some special harsh working conditions. For example: low temperature, high temperature, vacuum, underwater, heavy load, etc., due to the failure of grease lubrication and oil film can not be effectively formed, the traditional grease lubrication-based rolling bearing is difficult to carry and reduce friction. However, sliding bearings relying on solid lubricating materials can still show excellent performance in such environments. Mosaic self-lubricating bearing as a solid lubrication bearing is based on wear-resistant metal material, and by adding various lubricating materials to reduce the friction coefficient and realize self-lubrication. The material structure combines the advantages of high load, good impact resistance and low friction coefficient of non-metal, which is suitable for different working conditions. The inlay solid lubrication bearing is suitable for low speed, high load, and can keep very low friction coefficient in the case of oscillation, reciprocating motion, frequent starting and other grease can not maintain a complete lubrication film.

Steel base inlay self-lubricating bearing: Steel base inlay self-lubricating bearing is an enhanced product with high compression performance. It can discharge lubricating particles during the working process, so that a diaphragm is formed between the bushings, with better anti-blocking than single oil lubrication, with better anti-bite performance than single oil lubrication, and with high compression performance and the ability to discharge lubricating particles during the working. It is especially suitable for the support parts of lifting machinery.
For example: winch support, crane support, but not suitable for water or acid and alkali occasions.
Cast iron inlaid self-lubricating bearings.
Cast iron inlay bearing is a new product of solid lubricant with HT 250 as base material, which is a typical material saving product. If the pressure is less than 14.5N/mm~2 or mechanical performance requirements, it can be used as a substitute for JDB-2 material, which can greatly reduce the cost and meet the usage requirements.
For example: mold guide pillar, injection molding machine mold frame and other fields can be fully used.
4, steel-based copper alloy inlay self-lubricating bearings.
