China Bronze Graphite Bushings Manufacturer

The bronze graphite bushings 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, thrust washer bearings, 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.

Graphite Bushings And Bearings – Custom Material & Size

Graphite bushings and bearings 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 extremely high/lower temperature conditions with low speed. This material provides a maintenance-free bushing solution, particularly for high-load, intermittent oscillating motion.

Plugged Graphite Bushing | Features

  • May work without oil for long periods
  • Extremely high load capacity, with good anti-wear and lower friction
  • Particularly appropriate for low-speed and high load
  • Suitable for reciprocating, oscillation, or Intermittent motion where an oil film is hard to form
  • Good chemical resistance and anti-corrosion characteristics
  • Can be used in a wide range of temperatures from -40°c~+300°c
  • The bronze graphite bushings do not require oil grooves, and the graphite embedded in the matrix forms a self-lubricating film during operation, protecting the shaft from strain.

Graphite bushings impregnated To Achieve Self Lubricating

The so-called no oil supply means that there is no need to add oil or less oil. Our research aims to ensure that the graphite bushings impregnated 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 graphite bushings impregnated 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.
