1. Swivel is made of metal junction structure, the upper and lower joint part, intermediates and other parts are completely made of high quality forged alloy steel. Going through strict heat treatment after roughing process, then adopts refined processing, which make the swivel with perfect comprehensive mechanical property, strong wear-resistant and long life.
2. The inner bearing parts adopt imported bearings, SKF, FAG, excellent performance and long life.
3. The sealing elements are completely made of imported seal, NOK, which make it integrates anti-corrosion, not easy aging and good sealing property,make sure the oil in the inner cavity is not easy to leak, and the peripheral mud sundries cannot enter the inner cavity of bearing easily, so as to ensure the normal operation of the bearing .
