TAPERED ROLLER BEARINGS

Timken offers the most extensive line of tapered roller bearings in the world.Tapered bearings are uniquely designed to manage both thrust and radial loads onrotating shafts and in housings. We manufacture nearly 26,000 bearing combinations – in single, double and four-row configurations. Sizes range from an8mm (0.31496”) bore to a 2,222.5 mm (87.5”) outside diameter (OD). Customized geometries and engineered surfaces can be applied to these bearings to further enhance performance in demanding applications.

Single-Row Bearings

Single-row tapered roller bearingsconsist of four independent components: the cone (inner ring), the cup (outer ring), the tapered rollers and the cage. The tapered angles allow the bearings to handle a combination of radial and thrust loads. Timken
® single-row tapered bearings are commonly applied in wheels, transmissions, gear reduction units and a wide array of rotating industrial equipment.Single-row tapered roller bearingshave positive roller alignment that ensures true rolling motion and generates a “seating force” that pushes the roller against the cone large rib. This seating force prevents the rollers from skewing off apex, thereby keeping them positively aligned and located against the cone large rib. During assembly, tapered bearings can be preset to required clearance (end play) or preload conditions for optimum performance.TS bearings are the most widelyused design. TSF bearings are single- row tapered bearings that have flanged cupsto facilitate axial location and accurately align seats in through-bored housings.TSL bearings are similar to TSvarieties but feature DUO-FACE
