6201ZZ vs 6202 Ball Bearings: Which One for Your Electric Motor?

The 6201ZZ ball bearing and the 6202 are two of the most common bearings in small electric motors. They look similar, but the size difference matters when you are matching a bearing to a shaft. Here is a quick comparison.

Dimensions

Both are single-row deep-groove bearings in the 6200 series. The key difference is the bore: the 6201 runs on a 12 mm shaft (32 mm OD, 10 mm wide), while the 6202 runs on a 15 mm shaft (35 mm OD, 11 mm wide). Always match the bearing bore to the motor shaft diameter.

Sealing: ZZ vs 2RS

The suffix tells you how the bearing is sealed. ZZ means a metal shield on both sides (low friction, good for higher speed); 2RS means a rubber contact seal on both sides (better dust/moisture protection). The 6201ZZ is double-shielded, while our 6202 2RS is rubber-sealed.

Which should you choose?

• Choose 6201ZZ for a 12 mm shaft, higher speed, sealed-for-life motor end shields.
• Choose 6202 2RS for a 15 mm shaft or dustier operating conditions.

Both handle radial and moderate axial load and both suit fans, pumps, power tools and BLDC motors. Not sure which fits?
