Bearing

Bearings support rotating parts and reduce friction with rotating parts.

Motor Bearings

The bearings in motors are generally ball bearings, which provide smooth rotation and a longer service life.
The life of the motor is affected by the life of the bearings, and if the load and temperature applied to the bearings exceed the specification range, the life of the motor will be shortened.

Load Applied to Bearing

The loads applied to the bearing include loads applied in the axial direction to the motor shaft and loads applied in the direction perpendicular to the motor shaft.
The former is called "axial load" and the latter "radial load in motor and gear specifications, and each product has different permissible values.
