40 Series Casters with A1 Top Plate (2-3/8" × 3-5/8") are dependable, light-to-medium duty casters for carts, racks, shop equipment and everyday material handling. One listing, five wheel choices, so you can match the wheel to your floor and load.

Wheel types

• Infiniti (Annular Bearing) – Grey or Blue. Smooth, easy rolling under load; helps protect floors and resists wear in busy areas.
• Polyurethane on Polyolefin (Centered Bearing) – Red, Black or Grey tread on a grey core. Quieter than hard wheels, floor-friendly and long wearing.
• Hard Rubber – economical, all-around wheel.
• Soft Rubber – quiet rolling and extra floor protection.
• Cast Iron (Semi-Steel) – durable choice for rough floors and shop use.

Every caster uses the A1 top plate (2-3/8" × 3-5/8") for simple bolt-on installation. Choose your wheel type, size and caster style (Swivel, Rigid, or Swivel with Top-Lock Brake) from the dropdowns.
