Maintenance of metal linear bearings: lubrication and friction: anti-corrosion oil is injected into the linear bearing. If grease is used for lubrication, first use kerosene or organic solvent to remove the anti-corrosion oil, and then add grease after air drying. (It is recommended to use lithium soap grease marked with viscosity No. 0.2.) If lubricating with oil, it is not necessary to remove the anti-corrosion oil. According to the temperature change, the lubricating oil of ISO viscosity grade VG15-100 can be used. Shaft lubrication can be from the oil supply pipe Supply oil, or supply oil from the oil hole on the outer bearing housing. Since the sealing ring will scrape off the lubricating oil, oil lubrication is not suitable for non-porous bearings with sealing rings.
Maintenance of plastic linear bearings: Since the sliding film inside the plastic linear bearings is made of self-lubricating plastic, there is no need for additional oil supply and maintenance during use; and because the plastic linear bearings have chip grooves, even the bearing Or the shaft is packed with dust and there is no need to maintain it. The dust will automatically be taken out from the chip flute during the movement; only when the sliding film wears out, the internal sliding film can be replaced directly; the maintenance is very convenient.
