Tapered Roller Bearings
1. Description
Tapered roller bearings are separable bearings with tapered raceways on both the inner and outer rings. The rollers have a rounded shape, and the contact between the rollers and raceways is line contact. This design allows them to handle heavy radial and axial loads, as well as pure axial loads. The larger the contact angle, the higher the load capacity.
The taper of the rollers is designed so that the contact lines of the inner and outer raceways extend at the same point on the shaft, ensuring pure rolling. Based on the number of roller rows, these bearings can be classified into single-row, double-row, and four-row tapered roller bearings, with imperial sizes also available.
2. Structure
Single-row tapered roller bearing
Double-row tapered roller bearing with two outer rings
Tapered roller bearing with a large taper angle
Double-row tapered roller bearing with two inner rings
Single-row tapered roller bearing with capped edge on the outer ring
Four-row tapered roller bearing
Double-row tapered roller bearing with double inner rings
Imperial size tapered roller bearings
3. Cage
A steel stamping cage is typically used, while for bearings with diameters over 650mm, a roller-pillar welding cage is employed.
4. Features
High load capacity
Long service life
5. Applications
Single-row: Front and rear wheels of vehicles, machine spindles, railway vehicles, rolling mills, construction machinery, lifting equipment, printing machines, and various speed reducers.
Double-row: Machine spindles and rolling stock
Four-row: Rolling bearings
