Welcome to Linqing Xinshengdi Bearing Co., Ltd.
30224 Tapered Roller Bearing
- Dimensions: 120mm (d) x 215mm (D) x 43.5mm (T)
- Exceptional structural strength to endure continuous abrasive grinding.
- Thickened cup profile specifically optimized for vertical load vectors.
- Premium case-hardened steel prevents sudden fatigue failure under dust stress.
Power generation relies on the non-stop operation of heavy grinding mills. The 120mm bore 30224 bearing is specially heat-treated to operate inside coal pulverizers, where it absorbs relentless downward crushing pressure. Its optimized contact angle ensures uniform stress distribution, effectively combating the microscopic fatigue caused by coal dust infiltration and protecting the massive gear drives from catastrophic structural failure.
