SKL single-row tapered roller bearings are usually composed of inner rings, outer rings, tapered rollers and cage components, with a single row of tapered rollers and a separable design. They are typically used in conjunction with another set of tapered roller bearings, capable of withstanding high radial loads, and each set of bearings can bear unidirectional axial loads. Classified by dimensional units, they are divided into metric tapered roller bearings and inch tapered roller bearings.
