Maintenance Free Graphite Plugged Bronze Bushings Oilless Bushing For Mould Industry

JDB-90 bronze graphite oilless guiding bearing is made of centrifugal casting high strength brass with graphite filled. This type of self-lubricating bearing is also called #500 oilless bearing, guide bushes bronze with solid lubricant, bronze alloy oil free bushing, etc.

CuZn25Al6Fe3Mn3 + Graphite

Other materials can be made based on requirement

• Cost effective and higher crash strength comparing with other bronze graphite bearings
• The solid lubricant of oilless bearing will run out to the shaft through frictional heat, forming an excellent condition for the coexistence of oil and powder lubrication, which not only protects the shaft from wear, but also makes the solid lubricant persist
• Hardness is twice higher than other bronze graphite bushings

• Straight guiding bushing, collar guiding bearing, thrust washer and slide plate are standard fabrication
• Special designs and materials can be made according to your design

JDB-90 Oilless guiding bushing is widely used for automotive mould industry, punch mould industry, plastic mould industry and etc.
