Wide flanges resist rollover
High-strength steel and deep hardening virtually eliminate wear, shock loads, and bell mouthing
Sleeve bearings and large hardened shafts absorb impacts and deflection


Track Rollers & Bottom Rollers

Tractor-style rollers have an upset center shaft to absorb heavy thrust loading and offer at least 30% more wear life than excavator-style rollers. Best for machines that spend a lot of time traveling at high speeds.

Excavator-style rollers are better in high-impact conditions because of its heav-duty, large diameter shaft.

We provide the finest top quality Rollers which are guaranteed to be interchangeable with the original equipment manufacturer.

Roller shells are forged from a boron alloy steel and are through hardened. Some smaller excavator shells are induction hardened at the wear surface.
