ProductsInch single row tapered roller bearings are different from the metric bearings in structure, mounting dimension and rotate speed precision.
Inch single row Tapered roller bearings are generally of separable design and have tapered cone and cup raceway between which tapered roller are arranged, their design makes Inch single-row tapered roller bearings particularly suitable for carrying combined (radial and axial ) load.
WRT tapered roller bearings have single, double and four-rows. WRT manufacture both metric and inch size tapered roller bearings
