Welcome to Linqing Xinshengdi Bearing Co., Ltd.
32310/55 Non-Standard Tapered Roller Bearing (55mm Bore)
- Custom Bore Dimensions: 55mm Bore x 110mm OD x 42.25mm Total Width
- Replaces the standard 50mm bore with an enlarged 55mm inner ring while retaining the heavy 32310 outer cup profile.
- Eliminates the need to remachine the outer housing when upgrading to a thicker 55mm shaft.
- High-purity steel matrix engineered to withstand extreme rotational shock.
32310/55, Custom 32310-55, 32310 Modified Bore, Special 55x110x42.25mm Bearing
Standard metric catalogs often limit engineering options when upgrading shaft diameters. The 32310/55 is a highly specialized, non-standard tapered roller bearing designed to bridge this gap. Featuring an enlarged 55mm internal bore instead of the standard 50mm, it preserves the robust 110mm outer diameter of the classic 32310 series. This precise geometric modification allows mechanical rebuilders to install a thicker, higher-torque shaft directly into the existing equipment housing, drastically minimizing machining downtime.
