Maintenance of metal linear bearings: lubrication and friction: anticorrosive oil is injected into linear bearings. If grease is used for lubrication, the anticorrosive oil is removed with kerosene or organic solution first, and then lubricating grease is added after air drying. (Lithium soap grease with sticky label N0.2 is recommended.) If the oil lubrication, do not need to remove the corrosion oil, according to the temperature change can choose ISO viscosity grade VG15-100 lubricating oil. Shaft lubrication can be fed from the oil supply line, or from the oil hole in the external bearing housing. Oil lubrication is not suitable for non-perforated ring bearings because the sealing ring will scrape off the lubricating oil.

Maintenance of plastic linear bearing: because the sliding film in plastic linear bearing is made of self-lubricating plastic, it does not need additional oil supply and maintenance in the process of use; And because the plastic linear bearing has a chip slot, so even if the bearing or shaft is filled with dust, there is no need to maintain, the dust will automatically be brought out from the chip slot in the process of movement; Only when the sliding film wear failure directly replace the internal sliding film can be; Very easy to maintain.
