18" to 20" Urethane on Iron Wheels

High capacity, resistant to abrasion, chemicals, and oils

  • Urethane on Iron wheel is liquid cast and chemically bonded to machined, cast-iron cores

  • Capacities rival those of steel wheels (listed wheels up to 3,000 pounds each)

  • Careful attention is paid during the bonding process to assure that each wheel meets high performance standards

  • UI wheels are non-marking, resistant to abrasion, chemicals, and oil

  • All 18" and 20" wheels have a 5-1/2" hub length

  • Temperature range: -40º to 180º F

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.
