Maintenance of plastic linear bearings

Since the sliding film in the plastic linear bearing is made of self-lubricating plastic, it does not require additional oil supply and maintenance during use; and because the plastic linear bearing has a chip groove, even if the bearing or shaft is full of dust There is also no need to maintain, the dust will be automatically taken out from the chip flute during the movement; only when the sliding film is worn out, the internal sliding film can be replaced directly; maintenance is very convenient.
