Description:
Deep Groove Ball Bearings are one of the most widely used rolling bearings.
Low friction, high speed limit, cost-effective ball bearings, almost maintenance-free.
Suitable for all kinds of industrial equipment, micro motors, small rotary motors, office equipment, etc.

Selection Guide:
Shield (specify suffix Z/ZZ) - high speed. Prevents dirt and debris.
Seal (Designation Suffix RS/2RS) - Made of steel sheet reinforced NBR (oil and liquid resistant). Lower speed limit than Shield bearing.

1. ABEC-1: The basic level of the national standard. The dimensional accuracy is less than ±0.05mm, and the speed is less than 500rpm, which is suitable for low-speed and low-requirement environments.

2. ABEC-3: National standard P0Z2 level or above. The dimensional accuracy is less than ±0.01mm, the hand feels smooth, the speed is less than 6000rpm, the noise is low, and the service life is long.

3. ABEC-5: National standard P6 or above. The dimensional accuracy is less than ±0.005mm, the hand feels smooth, the speed is greater than 6000rpm, low noise, and long service life.
