4" x 2" Polyurethane Casters

These 4 in blue solid poly casters fit shop carts, equipment, and material handling carts that move heavier loads. Casters in this collection are rated 750 lb per caster. Wheels are 4 x 2 in swivel, rigid, and brake models. Solid polyurethane (poly or urethane) is quiet, floor safe, and resists water and many chemicals. Softer polyurethane or soft rubber or TPR tread is the better pick when the floor has chips or grit. Match the 4 x 4-1/2 in plate, bolt pattern, and overall height before you order. Choose swivel casters when the cart must turn in place, rigid casters for straight travel, and add a brake when the cart needs to stay put. Read the listing for the exact wheel size, overall height, and mount shown. Confirm the load rating printed on the title before you order. Measure the old wheel or caster before you buy. Polyurethane wheel aisle: polyurethane wheels. Plate aisle: plate casters.

Mount: most 4 x 2 in blue polyurethane casters use a 4 x 4-1/2 in top plate; measure bolt hole centers on the old plate and compare.
Floor: on 4 x 2 in blue polyurethane casters, polyurethane protects finished floors and runs quietly; check the rating if the cart also crosses rough concrete.
Rig: swivel and rigid 4 x 2 in blue polyurethane casters are listed, with total lock brake options.
