Definition, classification and characteristics of ordinary structure high temperature bearing

Characteristics, uses and matching skills of tapered roller bearings

Tapered roller bearings are separable bearings. Both the inner and outer rings of the bearing have tapered raceways, and the rollers are in the shape of a truncated cone. The rollers are in line contact with the raceway, which can bear heavy combined radial and axial loads, and can also bear pure axial loads. The larger the contact angle, the higher the axial load carrying capacity.
