HT250 Oiles Bearing Graphite Rings Plugged Casting Iron Solid Self Lube Bearings

JDB-70 Casting Iron Solid Lubricant Rings Plugged Oiless Guide Bearing

JDB-70 cast iron graphite ring filled guide bearing  is made of centifugal casting steel with graphite ring. This type of self-lubricating bearing is widely used in mould industry. It's also called Headed oiless guide bush,#500 cast steel oilless bearing.

• Especially suitable for reciprocating linear motion
• Due to the effect of friction heat, the solid lubrication material in the groove on the inner diameter surface will expand slightly, which will produce a friction with the shaft in the first place and form a transfer membrane on the shaft, so as to reduce the friction factor, reduce the wear of the shaft and shaft sleeve, prolong the service life

• Cylindrical oiles bushing, flanged oiles bushing
• Special designs and material can be made according to your design.

JDB-70 solid lubricant rings filled cast iron oilless guiding bearing  is widely used in Guide bushings of precision molds,Precision guide rails.
