China Graphite Bearing Supplier

The graphite bearings are machined from continuous cast bronze bar stock. They are then milled and plugged with solid lubricant graphite-based plugs. The plugged graphite bushings are great for applications where maintenance is difficult and where normal grease and oil-based lubricants can burn off due to high temperatures. The cast bronze base material gives these products stronger bearing abilities when compared to other self-lubricating bronze bushings.

Variable backing materials, such as bronze, brass, and other iron-based materials, are available for the oil-free graphite bushing.

We produce sliding plates, half-bearings, flanged bushes, and cylindrical bushes in a range of forms and shapes from graphite bushes. It can also create any customized form or size to satisfy the customer’s requirements.

Bronze Graphite Bushing – Custom Material & Size

Graphite Plugged Bushings are a complete line of Self-Lubricating Bushings that excel whenever standard lubrication is impractical, including heavy load, and high-temperature applications. Graphite Bushings with a solid lubricant are made of strong cast bronze based metal with special solid lubricants embedded. , including C95400 Aluminum Bronze, C93200 Bearing Bronze, and C86300 Manganese Bronze. The bushing shows excellent performance without pre-lubrication under conditions of extreme high/lower temperature with low speed. This material provides a maintenance-free bushing solution, particularly for high load, intermittent oscillating motion.

To Achieve Self Lubricating

The so-called no oil supply means that there is no need to add oil or less oil. The goal of our research is to ensure that the bearing can still perform well under this working condition and prolong its service life as much as possible. The basic working principle of self-lubricating bearings is that in the initial running stage, the solid lubricant on the bearing surface forms a transfer film due to mutual friction and coats the opposite abrasive parts to form a solid lubricating film to achieve the purpose of self-lubricating. The direct contact between the workpieces thus protects the abrasive parts and prolongs the service life of the bearing and the workpiece.

Base Metal and Alloys

Selecting the proper base metal and alloy is crucial to the successful application of self-lubricated bushing. There are many factors to consider that influence the bearing suitability of the application. Some are Speed, Load, Environment, Mating Material, and Temperature.
