4" Stainless Steel Top Plate Rigid Caster with Hi-Temp Polypropylene Wheel - D4.04108.831 RW SS

About This Caster - D4.04108.831 RW SS

Choose this 4-inch Defender D4 rigid when a hot wash-down line needs a caster with nothing to grease or corrode.

It pairs a stainless steel frame with Colson's blue hi-temp polypropylene wheel, the same heat-and-chemical-tolerant tread that handles retort and sterilization cycles up to 250°F, and runs it on a Delrin plain bearing. That bearing is the maintenance-free choice: no grease to flush out in a wash-down, nothing to seize when sprayed, and quiet running at the lighter loads it is sized for. The rigid mount tracks in a straight line for the back of a cart. As a hard plastic wheel it gives no cushioning and can scuff a soft floor, so it suits heat, moisture, and chemicals rather than a smooth or quiet ride.

Ideal applications

• Hot wash-down and sterilization lines needing a grease-free bearing
• Stainless carts sprayed with water and cleaning chemicals daily
• Lighter-duty straight-tracking corners in damp, high-heat areas

Keep the load within the Delrin bearing class and confirm the 5-5/8-inch mount height before ordering.

Pairs with: the hi-temp precision-ball rigid 49G41G42G-02 where faster tow-line roll matters more than grease-free duty.

Wrong fit? Heavier loads at slow speed? See the hi-temp roller rigid 49G41I42G-02 in the Colson collection.
