Tapered roller bearings consist of four independent components: the cone(the inner ring); the cup(the outer ring); the tapered roller(the rolling elements); and the cage(the roller retainers). This type bearings are designed to accommodate both radial and axial loads.

Taper roller bearings are produced by HRT bearing in many designs and sizes to match their many uses. These can be grouped as follows:

• Single-row taper roller bearings
• Double-row taper roller bearings TDO
• Double-row taper roller bearings TDI
• Four-row taper roller bearings TQO
• Four-row taper roller bearings TQI
• Paired single roww taper roller bearings DB
• Paired single roww taper roller bearings DF
• Paired single roww taper roller bearings DT
• Special taper roller bearings
