The loading plate holds the mast roller securely on the stub shaft, and also pre-loads the bearing assembly.
Extremely high capacity mast rollers utilizing two opposed tapered roller bearing assemblies.
This series is recommended when side loading is an issue.
The opposed tapered roller bearings can withstand combined radial and axial loads.
We supply these with all required spacers and seals; no further shimming or adjusting should be required.
The inner spacer is typically drilled radially to allow for re-lubrication through the stub shaft.
We offer custom sizes, coatings, greases, etc. with very low minimum production runs.
