4" to 5" Forged Steel Wheels

For the toughest applications...the most demanding floor surfaces

  • Forged steel wheels are hot-forged from medium carbon steel, providing maximum strength and durability—even under extremely heavy loads

  • Forged Steel wheels are virtually indestructible within their capacity range

  • Use them in the toughest applications and on the most demanding floors, with the heaviest load

  • Temperature range: -50º to 800º

Straight Roller Bearings

Straight roller bearings consist of a cage-type roller assembly and a split outer race.  These bearings turn on hardened and ground spanner bushings which provide a long wearing precision inner race.  Press fit combination metal retainer/thrust washers hold the bearings in place.  Straight roller bearings have a high radial capacity, but minimal side thrusting load rating.

Tapered Bearings

Tapered roller bearings are true precision bearings designed for the heaviest loads, and/or high-speed operation.  In addition to great radial capacity, they have a side thrust load rating of 60% to 90% of radial capacity rating.  The assembly consists of an outer race or cup and a tapered cone roller assembly held in position with closures.  Spacers are provided to tighten the caster legs against the bearing assembly.  Two bearings are installed per wheel.
