JDB-70 Casting Iron Solid Lubricant Rings Plugged Oilless Guide Bearing
JDB-70 cast iron graphite ring filled guide bearing is made of centrifugal casting steel with graphite ring. This type of self-lubricating bearing is widely used in mould industry. It's also called Headed oilless guide bush, #500 cast steel oilless bearing.
Material
HT250 + Graphite Rings
Other base materials can be made based on requirements
Characteristics
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 friction with the shaft initially and form a transfer membrane on the shaft, reducing the friction factor, decreasing wear on the shaft and shaft sleeve, and prolonging service life
Special designs and materials can be made according to your specifications
Application
JDB-70 solid lubricant rings filled cast iron oilless guiding bearing is widely used in guide bushings of precision molds and precision guide rails.
