Replace the rollerhead bearings and shafts if you notice decreased smooth movement, unusual noises, or excessive play in the saw head. A loose yoke or reduced cutting accuracy also indicates wear or broken bearings. Regular inspections will help you spot these signs early to maintain optimal performance and safety.

Carefully inspect the shafts. If you notice rust, bending, damage from set screws, or a stripped hex Allen socket on the eccentric pin, it’s best to order the Rollerhead Bearing and Shaft Kit for a complete replacement.

Follow a regular maintenance routine to extend the life of your Radial Arm Saw’s rollerhead bearings and shafts. Clean moving parts, keep the saw track free of debris, and use denatured alcohol or brake cleaner with a clean rag to wipe down the tracks.

If replacing the rollerhead bearings and shafts doesn’t improve your saw’s performance, other underlying issues may exist. Try these troubleshooting tips: Inspect the track and arm: Ensure they are clean and free from dirt or damage, as buildup or wear can affect movement and alignment. Check for loose or misaligned components: Confirm all bolts, screws, and fasteners are properly tightened and aligned. Loose parts can cause vibration and affect cut accuracy. Examine the motor and blade assembly: If performance issues persist, check for wear or damage in the motor or blade. Make sure the blade is sharp and balanced.
