The basic dimensions of tapered roller bearings are listed in the size data sheet,
Single-row tapered roller bearings:
Inner diameter range: 20mm ~ 1270mm
Outer diameter range: 40mm ~ 1465mm
Width range: 15mm ~ 240mm
Double row tapered roller bearings:
Inner diameter range: 38mm ~ 1560mm
Outer diameter range: 70mm ~ 1800mm

Tapered roller bearings generally use steel plate stamping, basket cage, but when the size is larger, it is also used to make solid pillar cage.
1. When the bearing outer diameter D≤650mm, the steel plate stamping cage is used, and the code behind the cage is not marked
2. When bearing outer diameter D> At 650mm, the steel solid pillar cage is used, and the rear code of the cage is not marked
