Deep groove ball bearing processing steps:

Kit fine hole: drill the stopper hole and oil hole on the surface of the kit, and prepare the inner surface of the roughing kit for the surface of the cold bore.

Cold expansion kit: For the cold groove expansion of the deep groove ball bearing ring channel, the core roller feed speed has 6 stages speed during the cold heading process, the speed range is 0.4mm/s~1.0mm/s, and the speed curve is one. The trajectory in the processing cycle is fast, slow, slow, until stopped; the rolling time is between 6s and 14s, and the helium pressure is 80KN;

Turning kit: chamfering the kit, sealing groove;

Fine grinding kit: fine grinding kit to improve the surface accuracy of the kit;

Install the bearing: place the ball between the ferrules, install the cage, inject grease, install the seals, and complete the assembly of the deep groove ball bearings.
