Cart Wheels & Casters - 4 Size Brackets, 600-9

This collection holds Cart Wheels Casters with phenolic, pneumatic and TPR wheels, built for shop carts, equipment, and material handling carts that move heavier loads. Casters in this collection range from 600 to 900 lb per caster. Wheels in this category range from 4 up to 10 inches in diameter with 2 to 3 in tread widths. The collection includes swivel, rigid, and brake models. Phenolic rolls easily on smooth floors and handles dry heat, oil, and grease, but it is not made for water or washdown. It suits warehouse carts, toolboxes, and tool carts, and it is loud on rough floors. Air filled and flat free tires cushion the load and roll over gravel, grass, cracks, and debris. Thermoplastic rubber (TPR) is quiet, will not mark floors, and rolls over chips and grit. Choose swivel casters when the cart must turn in place and rigid casters for straight travel. Phenolic aisle: phenolic casters. Wheel hub: replacement wheels.

Choosing cart wheels and casters

Load: plan on three casters carrying a four-caster cart [S2]; at 900 lb each, a common rating here, that is about 2,700 lb, and the 900 lb top rating covers about 2,700 lb.
Mount: most cart wheels and casters use a 4 x 4-1/2 in top plate; measure bolt hole centers on the old plate and compare.
Floor: on cart wheels and casters, polyurethane, pneumatic and rubber are kinder to tile and finished floors; phenolic rolls easier under heavy loads on smooth concrete.
Rig: swivel and rigid cart wheels and casters are listed, with side lock brake and top lock brake options.
