Radial

Pertaining to directions or movements that extend outward from a central point or axis, commonly used in describing mechanical parts or forces.

Thrust Loads

Forces applied parallel to the axis of a bearing, shaft, or axle, pushing against its lengthwise direction.

Roller Bearings

Bearings that use cylindrical rollers to maintain the separation between moving parts of a bearing, reducing friction and supporting radial and axial loads.
