33215 Tapered roller bearings 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

When single-row tapered roller bearings are used in pairs (the basic dimensions can be different), the additional axial force caused by the radial load must be taken into account when calculating the equivalent dynamic load of the bearing. The additional axial force S of a single row tapered roller bearing can be approximately calculated as follows: S= Fr/2Y
