6"X2" Stainless Steel Top Plate Rigid Caster with White Nylon Wheel - D4.06108.539 WN SS WB29

About This Caster - D4.06108.539 WN SS WB29

Pick this 6-inch Defender D4 rigid when a heavy sanitary cart carries weight slowly, clears thresholds, and needs a hard wheel that ignores moisture.

The roller bearing carries the most weight of the three bearings at a slow pace, and the white nylon wheel resists chemicals and moisture, stays stable when wet, and wipes clean. The taller 6-inch wheel rolls over door tracks and joints with the least effort, on a stainless steel frame for corrosion. Nylon leaves no color mark, but it is a hard wheel that gives no cushioning and can scratch a soft floor. Rigid means it tracks straight at the rear. It serves from -20 to 180°F.

Ideal applications

• Heavy 6-inch sanitary carts pushed slowly over thresholds
• Stainless transfer rigs needing an easy-clean hard wheel at capacity
• Rear corners on hard flooring under sustained heavy loads

Confirm the roller-bearing load class and that the floor accepts a hard nylon tread before ordering.

Pairs with: the 6-inch white nylon precision-ball rigid D4.06108.535 WN on faster lead corners.

Wrong fit? Need a quiet non-marking tread instead? See the 6-inch Performa grey flat-tread roller rigid D4.06108.459 in the Colson collection.
