OIL SEAL
The function is to prevent the entry of dust, dirt, sand and metal chips. Through special design, it prevents scratches, protects guide parts and prolongs the service life of the seal. The outer diameter with interference allows the dust ring to fit tightly into the groove, thereby preventing the intrusion of foreign particles and moisture. It tightly seals the cylinder body without screws and brackets. Since there is no metal insert, it will not rust like the metal skeleton dust ring. The groove does not require very strict tolerances.
