4" Top Plate Swivel Caster with Glass-Filled Polypropylene Wheel - 170RT04201S

About This Caster - 170RT04201S

Pick this 4-inch Empire 170 swivel when a cart needs to steer through a wet or high-heat area on a tough, low-cost plastic wheel.

The wheel is glass-filled polypropylene, a stiff reinforced plastic that handles -20 to 250°F and resists washdown chemicals and corrosion, a practical pick for caustic or humid areas where steel rusts and rubber breaks down. It is hard with no cushioning, so it rolls easily on smooth floors but passes shock through and can mark, and at 4 inches it carries up to 800 pounds on a roller bearing sized for manual pushing. The swivel turns on a kingpinless welded raceway with no central pin to loosen, bolts on a 4 by 4-1/2-inch top plate at a low 5-5/8-inch mount height, and wears a zinc-plated finish.

Ideal applications

• 4-inch economical Empire 170 black glass-filled poly swivel up to 800 lb
• Steering corners on washdown carts needing a corrosion-proof plastic wheel
• Maneuverable high-heat carts up to 250°F where rubber would break down

For a fixed wheel that tracks straight, the 170RT04201R is the rigid version.

Pairs with: two RT rigids on the fixed end and two of these swivels on the steering end of a cart.
