4" Stainless Steel Top Plate Rigid Caster with Polyurethane (hi-Tech) Wheel - D4.04108.929 SS WB29

About This Caster - D4.04108.929 SS WB29

Pick this 4-inch Defender D4 rigid when a heavy wash-down cart has to be floor-friendly and is pushed at a slow, steady pace.

The roller bearing is the heavy-haul choice in this group, carrying more weight than a ball or Delrin bearing as long as travel stays slow, which suits a loaded transfer cart. It runs Colson HI-TECH polyurethane on a polyolefin core, a non-marking tread that takes far more load than rubber, resists abrasion, and will not flat-spot under a parked weight, while protecting a finished floor instead of scarring it. The stainless steel frame stands up to corrosive, sprayed-down bays. Rigid means it tracks in a straight line at the back of the cart. It serves from -45 to 180°F. This is weight plus floor protection, without the noise of a hard wheel.

Ideal applications

• Heavily loaded wash-down carts moved at walking pace
• Stainless rigs that must carry weight without marking floors
• Straight-tracking rear corners under sustained heavy loads

Confirm the roller-bearing load class and the 5-5/8-inch mount height before ordering.

Pairs with: the HI-TECH poly Delrin rigid 49JH42G-02 on lighter, grease-free lines.
