Inch four 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 four-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
