- The double-row deep-groove ball bearing is dust-proof or hardened with carbon steel or cast iron on both the housing and nipple sides.
- It has a structure with sufficient strength against complex loads such as thrust, radial, and bending moment.
- By providing ball insertion plugs in one or two places and performing integrated processing with the ball race, it has a structure that does not completely interfere with smooth rotation.
