BUCHA BRONZE GRAFITADO
Process and Principle:
Special production process:
Due to the requirements of special production technology, some key equipment of industrial and mining enterprises run under extremely bad conditions. Due to the heavy equipment, high temperature, dust or air containing acid corrosion in gas CO, SO2, etc., bring many problems of equipment lubrication, friction and wear is serious, so far, most of the domestic enterprises is still using the traditional oil, grease, and the fact that the industrial and mining condition is beyond the scope of oil, grease, It is easy to bite or kill bearings and other friction pairs, causing serious wear and damage of parts, and often leading to equipment outage.
In order to produce continuous operation, in addition to the original design required the installation of multiple equipment wheel repair, also need to invest a large number of maintenance personnel. Seriously restrict the improvement of productivity, spare parts and energy consumption, has become an important obstacle to the development of production. Automobile manufacturing, cement production, petrochemical and other enterprises have put forward the requirements of special lubricating materials under complex working conditions.
Therefore, the research on inlaid self-lubricating composite material highlights its own characteristics in material formulation and preparation process, and the material performance has reached the international advanced level, which solves the lubrication problem under special working conditions for enterprises, and brings obvious economic and social benefits. But for a variety of reasons more domestic enterprises have not adopted, the situation still exists.
Key technical principles:
The composite material used for inlaid self-lubricating bearing is a new type of extreme pressure resistant solid lubricating material, which is composed of metal substrate and solid lubricant paste embedded in the hole or groove of the substrate. In the friction process, the metal substrate bears most of the load. After the friction, the solid lubricant in the hole or groove transfers to the friction surface or reverse transfer, forming a solid transfer film with good lubrication, firm adhesion and uniform coverage on the friction surface, greatly reducing the friction and wear. As the friction goes on, the solid lubricant embedded in the friction surface is constantly provided to ensure the good lubrication of the friction pair during long-term operation

Key Characteristics:
1. May work without any oil for long period.
2. Extremely high load capacity, good anti-wear, and low friction.
3. Particularly appropriate for low speed and high load.
4. Suitable single direction axial loads
5. Free design is possible on the shape and size
6. Can be used in a wide range of temperatures, from － 40℃＋ 300℃
Oil-free Bushing & Bronze Bearing Design
The geometry, as well as the choice of material, is based on the specific application of the bearing. This means that each bearing is specially made to meet all load, environmental, and temperature requirements where it is to be used.
Base material produces a wide range of copper-based alloys, which are used as base material on oil-free bushing bearings. Data relating to four of those alloys are given in the table below. The capacity or carrying load is very much dependent on the choice of alloy, The selection of the base material will thus be based on the requirement of load-carrying capacity. Note that the temperature has an influence on the allowable load values and also the choice of lubricant.

OIL-FREE BEARING SIZE
Oilless Lubricating Bushings: The Self-Lubricating Effect – bronzelube.com
Serviceable without the need for lubrication. Demonstrates high performance under high-load and low-speed operations. Demonstrates superior wear resistance in applications where oil film is seldom produced such as reciprocating motions, oscillation, frequent starts, and stops, etc. Superior chemical resistance and corrosion resistance. Standard products are available in various sizes. Applicable to rotation, oscillation, and reciprocating motion. Not for use underwater.

Manufacturer of castings OILES 500 bushing and machined components made of bronze. Manufacturing units are located in China;
Installation selflubricating bearings require minimum or no maintenance provided they are correctly dimensioned and installed. Their high strength will then give a long bearing life. The following points are important when installing the bearing:
oil-free bushing is specially packed for transporation. Please do not remove the protective cover until installation.
The sliding surface of the bearing is treated with a solid lubricant coating.
This is applied to improve the running-in process.
Please make sure that this film is not damaged at the installation.
Make sure the mating material is cleaned carefully. This is very important for the life of the oil-free bearing.
The bronze lubricating bushings release tiny amounts of solid lubricant during movement.
