C90800 Graphite Inlaid CuSn12 Bronze Bushing & Bearings
Copper Bearing finished copper alloy bushings provide a simple,
economical way to use bearings with high bearing, good corrosion resistance, dimensional processing any
of the characteristics. Meanwhile TOP BEARING can provide different copper alloys according to different
conditions, and in accordance with the requirements of processing
different forms, it has a higher dimensional accuracy than class
copper rolling bearings.

C90800 Bearing Bronze
TOP BEARING Offer the C90800 Bearing Bronze,cast bronze bushing &
plate.
TOP 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.
Advantages
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.

| 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.
Characteristics
● 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.
Availability
● 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.
