Tolerances for single row tapered roller bearings
ZYSL single row tapered roller bearings have common tolerances, and also provide P6X, P6, P5, P4, P2 tolerance products, all in line with GB307.1.
Inch tapered roller bearings have common tolerances, and CL2, CL3, CL0, CL00 tolerance products are also available upon request.
Radial clearance of single row tapered roller bearings
ZYSL single row tapered roller bearings have play only after installation and can only be determined after adjustment with another bearing positioned in the opposite direction.

Cages for single row tapered roller bearings
Tapered roller bearings generally use steel stamping and basket-shaped cages, but when the size is larger, a car-made solid strut cage is also used.
1. When the bearing outer diameter D≤650mm, the steel stamping cage is used, and the rear code of the cage is not marked
2. When the bearing outer diameter D>650mm, the steel solid pillar cage is used, and the rear code of the cage is not marked

Tolerance of single row tapered roller bearings
Equivalent Dynamic Load
P=Fr KN] When Fa/Fr≤e
P=0.4Fr +YFa [KN] When Fa/Fr>e
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 single row tapered roller bearings can be calculated approximately as follows: S= Fr/2Y
