Xr/Jxr Series High Precision Cross Tapered Roller Bearing Xr496051 for Machine Tool Rotary Table

Xr/Jxr Series High Precision Cross Tapered Roller Bearing Xr496051 for Machine Tool Rotary Table. Tapered rollers cross vertically at 90 inside V-shaped raceway. One single bearing supports radial load, bidirectional axial load & overturning moment altogether, replacing traditional double-bearing. Nylon separators between rollers prevent direct contact, reducing friction and wear. Pure rolling without sliding friction enables higher rotating speed vs cylindrical cross roller bearing. Nylon spacer features low inertia & low starting torque, low heat generation for medium-high sp. Slim cross-section same as single row bearing, two roller rows integrated in limited space, save housing material & equipment layout space, cut clients overall production cost. Carburized bearing steel & 42CrMo raw material, wear & fatigue resistant. Comprehensive pre-sales technical support and after-sales service. Mass production capability with stable delivery schedules.
