Suitable Applications

Before ordering, measure the existing overall spindle length, shaft diameter, roller bore and bracket width. The critical measurements for M-121070 are
- 240mm overall length × 18mm diameter
- 9.45" overall length × approximately 23/32" diameter
- The roller bore must be slightly larger than the spindle to provide adequate running clearance and allow the roller to rotate freely.
Signs the Roller Spindle Needs Replacing
- Replace the spindle if it shows bending, heavy corrosion, deep wear grooves, excessive shaft wear, damaged retaining points or deformation. Also inspect the roller bore and bracket for excessive wear before fitting a new spindle.
