Excellent All-round Capabilities RG7 Bronze Bearing
Easy To Machine
Offering good dry running characteristics and pressure-tightness, RG7 tin bronze bushing is easy to machine and finds use in the production of slide bearings and bearing bushings. It provides adequate corrosion resistance, including saltwater environments. RG7 is soft solderable (hard solderability is possible but limited). Commercial applications for this engineering material include:
Slide bearings, sliding partsBearing bushesValve and pump housingsSteam fittingsStandard bearings
We stock RG7 (G-CuSn7ZnPb) tin bronze bushing in thrust washer, wear plate, straight and flange type.


SAE660 Tin Bronze Bearing With Graphite
Graphite tin bronze bushing is a kind of novel lubrication bearing that has both the characteristics of metal bearing and self-lubricating bearing, by 93200( rg7 ) tin bronze to bear the load, the special formula of solid lubricating graphite material plays the role of lubrication. C93200 bearing bronze has a high bearing capacity, impact resistance, high-temperature resistance, self-lubricating ability, etc. It is suitable for heavy load, low speed, reciprocating or oscillating, and difficult to lubricate and form oil film, and is not afraid of water and other acid corrosion and scouring.

Automotive Bearing – C93200 Bearing Bronze
C93200 automotive bearing on the car are mainly installed in the chassis part because there are various suspensions and control arms under the chassis, and these parts are connected through the pivot, to reduce the mutual wear and tear between the parts, so the middle of the suspension system of the car is connected by a large number of bronze bushings.
Shock Absorption Function Bearing
In addition to reducing wear and tear, easy to replace, the biggest role of the car C93200 bearing bronze is also has a certain shock absorption function. Generally, the upper and lower control arms of the car shock absorber will be connected with bushings, when the vehicle through the bumpy road will produce high-frequency vibration, in addition to shock absorbers and tires can absorb vibration, a variety of suspension bushings can also absorb part of the vibration, to avoid as far as possible to transfer vibration into the cockpit, improve the comfort performance of the vehicle.
