Structure: Aluminum brass base – machine annular groove then fill in solid-lubricant

Feature:
1.Due to the effect of friction heat, the solid lubrication material in the aluminum brass 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 coef., reduce the wear of the shaft and shaft sleeve, prolong the service life
2.Especially suitable for reciprocating linear motion conditions

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