1. Match the inner diameter of the radial bearing with the shaft, match under normal load without impact, and choose H7 tolerance grade for the recommended shaft with an inner diameter less than 100.

2, the matching of radial bearing outer diameter and bearing seat, the matching of normal load without impact, the recommended bearing seat with outer diameter less than 120 choose H7 tolerance level.

3, choose a clean, dry place before installation, and keep the workplace and tools clean.

4, before the installation, open the bearing packaging, bearings do not need to be cleaned.

5. When installing bearings, under no circumstances can you directly tap the bearing ring, cage, rolling element or seal. The force must not pass from the inner ring to the outer ring or the outer ring to the inner ring through the rolling element, otherwise it may cause damage to the raceway.

6, with a sleeve in contact with the inner and outer ring end face at the same time, the contact surface must be on the same plane, the outer diameter of the sleeve is less than the outer diameter of the bearing, the inner diameter of the sleeve is greater than the inner diameter of the bearing, and by hammering or hydraulic method, to ensure that the pressure acts on the inner and outer rings of the bearing at the same time. Install the bearing in place. When tapping, it should be acted on the bearing ring as evenly as possible to prevent the bearing from tilting or skewing.
