Login4" to 5" 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
-
These wheels will typically outlast rubber wheels
-
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. |
