Single row deep groove ball bearings.

Simple structure, easy to use, high output, low price; and the friction coefficient is small, high speed, so it is the most widely used in the market.

Z               2Z

Z：Single side deep groove ball bearing with dust shield.

2Z：Deep groove ball bearings with dust shield on both sides.

Dust can be prevented from entering the bearing interior, without cleaning or adding grease before use.

RS：Deep Groove ball bearings with single side seal (contact).

2RS：Deep groove ball bearings with seal on both sides (contact).

The sealing lip is in contact with the edge of the inner ring, which has a good sealing effect, but the friction resistance is large and the speed is relatively low.

RZ：Deep groove ball bearings with single side seal (non-contact).

2RZ：Deep groove ball bearings with seal on both sides (non-contact).

The sealing lip does not contact the edge of the inner ring. For a non-contact seal, the bearing does not need to be cleaned and lubricated during installation and use.

N

N：Deep groove ball bearing with snap ring groove on the outer ring.

Bearings with snap ring grooves are installed with upper snap rings to prevent axial movement of bearings.
