Ball Bearing (Spindle/Arbor Side)
This bearing supports the main arbor shaft where the blade is mounted. Over time, sawdust particulates penetrate the bearing seals, resulting in abrasive wear of the internal race and ball bearings, which leads to blade runout and vibration.

Armature Ball Bearing (Fan/Drive End)
Located on the motor armature, this bearing operates at very high RPMs and is subject to significant thermal stress. Failure occurs when the lubricant dries out or is displaced by centrifugal force, leading to 'whining' noises and increased motor friction.

Grooved Ball Bearing (Glide Arm Linkage)
These bearings are part of the Axial Glide articulating arm system. While more robust than motor bearings, they can develop 'stiction' or play if the saw is used in extremely dusty environments without proper dust extraction, causing the arm to feel stiff or inaccurate.
