Description
Electric Motor Deep Groove Ball Bearing
An electric motor deep groove ball bearing is the workhorse bearing that supports the rotor shaft inside almost every electric motor. Its deep raceway grooves let it carry radial load, thrust load in both directions and combined loads at high rotational speed — all with very low friction, which is exactly what an efficient, long-life motor needs.
Why deep-groove bearings suit electric motors
Because the balls sit in a deep, closely-conforming groove, this bearing type runs cool and quiet even at the high RPM of a running motor. Shielded and sealed versions hold their grease for life, so the motor’s end shields stay clean and maintenance intervals stretch out. That combination of low noise, low heat and long service life is why deep-groove ball bearings are the default choice for fan, pump and appliance motors.

Frequently asked questions
Why are deep-groove ball bearings the standard for electric motors?
Deep-groove ball bearings handle radial AND axial (thrust) loads, run at high speeds, have low friction, need minimal maintenance and are the lowest-cost precision bearing type — the ideal match for the load profile of a typical electric motor shaft.
Which size do I need for a 1 HP motor?
Most 1 HP single-phase and small 3-phase motors use 6205 (25 mm bore) as the drive-end bearing and 6203 (17 mm) or 6204 (20 mm) as the non-drive-end. Check your motor shaft diameter to confirm.
ZZ (shielded) or 2RS (sealed)?
ZZ for higher-RPM / drier motors (ceiling fans, industrial motors). 2RS for wet/dusty conditions (pumps, outdoor motors). See our deep-groove bearings guide.
