4. When the labyrinth seal is used, the inner and outer seals are respectively loaded into the rollers to avoid sealing deformation and affect performance.
5. Lithium-based lubricating esters occupying 2/3 of the gap between the inner and outer seals of the bearing should be added.
6 The direction of bearing installation shall be such that the nylon cage opening is outward. After the bearing is loaded into the roller, proper axial clearance shall be maintained and shall not be crushed. Each piece of the roller is flexible and can be transferred to the next process.
