FAQ
What is four‑point‑contact in slewing bearings?
Four‑point‑contact means each steel ball forms four contact points against the inner and outer gothic‑arch raceways. This special raceway geometry enables a single slewing bearing to accommodate bidirectional axial loads, radial loads, and tilting moments at the same time.
How to maintain four‑point‑contact ball slewing bearings?
Regular maintenance includes regreasing every 100‑200 operating hours, verifying bolt tightening torque, checking seals for wear or damage, and watching out for abnormal noise and excessive play during operation.
Can your bearings replace Rothe Erde, SKF or IMO?
Yes. Our four‑point‑contact ball slewing bearings follow standard dimensional specifications and are interchangeable with Rothe Erde, SKF, IMO, INA, Kaydon and other mainstream brands. Kindly provide your original part number for cross‑reference checking.
