C90800 Bearing Bronze
We Offer the C90800 Bearing Bronze, cast bronze bushing & plate.
Viiplus graphite plugged tin bronze oiles bearing is based on tin bronze material. This type of self-lubricating bearing is also called #500 oilless bearing,brass bearing,cooper bushing,solid sliding bearing,guide bushing and graphite filled bearing.
The tin bronze graphite inlaid bearing is based on CuSn12 material. Compared with CuSn5Zn5Pb5, CuSn12 increases the tin content and reduces the friction coefficient, but the relative cost increases.The product is embedded with graphite oil as solid lubricant, which can achieve the effect of lubrication without oil.The product is mainly used in low load, relatively high temperature, medium speed occasions, such as construction machinery 'metallurgy machinery, paper machinery, transport machinery in the lubrication difficult parts.
Solid bronze bearing is a standard item of our company. This type self-lubricating bearing is also called solid metal bearing,graphite plugged bearing,solid lubricating bearing,guide bushes,cast bronze bushing, #500 oilless bearing,oiles flange bearing and solid sliding bearing.
In places where oil film formation is difficult, such as reciprocating movement, swing movement, frequent starting and stopping, excellent wear resistance can be exerted:
The arrangement principle of the lubricants of the solid lubrication bearing is to ensure that there are lubricants on all parts of the grinding parts in the running process. Therefore, the arrangement position of the lubricants must be determined according to the movement direction of the grinding parts.

| 3" or Less | ±.0010" |
| Over 3" | ±.0015" |
| Outside Diameter | |
| 3" or Less | +.002" to .003" |
| Over 3" | +.003" to .005" |
| All Lengths | ±.005" |
| Concentricity | .003" T.I.R. |
Clearance
Greater than normal clearance must be allowed: (1) if exceptionally high speed is involved, (2) if higher than normal loading is encountered.
Material Structure
Standard material: CuSn12 + Graphite.
● Have Incomparable performance under a high load, low speed operation. Also perform well without lubrication;
● Excellent wear resistance in such places where an oil film is difficult to be formed due to reciprocating, oscillating motions and frequently intermittent operations;
● Remarkable resistance to corrosion and resistance to chemical attack;
● Maintenance free and save operating cost.
● Cylindrical oiles bushing, flanged oilless bush, thrust washer and slide plate are standard fabrication.
● Special designed solid metal bearing and material can be made according to your design.
● Other material can be made based on your requirement.
