UAV bearing specification

Select for the
operating conditions.

RHD imports and distributes miniature and standard deep-groove ball bearings for UAV motor applications. Motor RPM is not a bearing speed rating: suitability must be validated for the series, size, load, lubrication, clearance, fit, temperature and duty cycle.

RHD V4 bearing range

Low-vibration bearings for UAV motors.

Series, internal clearance, lubricant and closures are matched to the motor design and operating conditions.
