Structure：High strength casting iron –MoS2 solid lubricant filled in the spiral groove with a certain pitch

Feature
1.Especially suitable for reciprocating linear motion
2.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

Application
1.Guide bushings of precision molds
2.Precision guide rails.
