How does the SFPR58-4 flange kit improve wheel stability?

The flange provides a precise mating surface between the buffing wheel’s centerplate and the machine spindle, reducing wobble and uneven wear. Proper flange engagement keeps the wheel concentric under load, which helps produce consistent polishing results.

• Fits 3" centerplates to support wheel seating.
• Designed for 5/8" arbor shafts for secure attachment.
