- 172mm overall length × 16mm diameter
- 6.77" overall length × approximately 5/8" diameter
- Do not select a spindle solely by the nominal roller width, as different roller brackets can require different spindle lengths.
Signs the Roller Spindle Needs Replacing
- Replace the spindle when it shows bending, heavy corrosion, deep wear grooves, shaft deformation, damaged retaining points or excessive wear where the roller rotates. Inspect the roller bore and bracket at the same time for excessive movement or wear.
