4" Stainless Steel Top Plate Rigid Caster with Performa Rubber (Flat/Grey) Wheel - D4.04108.459 SS WB29

About This Caster - D4.04108.459 SS WB29

Pick this 4-inch Defender D4 rigid when a quiet, non-marking cart needs to carry near the top of the soft-rubber range, pushed slowly.

The roller bearing is the highest-capacity of the three bearings offered, so it lets the grey flat-tread Performa wheel work toward its load limit as long as travel stays slow and steady. Performa is Colson's quiet institutional rubber that protects finished floors and leaves no marks, and the flat profile puts more rubber on the ground for a stable, planted roll. The stainless steel frame handles corrosive, sprayed-down bays. Even with the roller bearing, soft rubber tops out below a hard poly wheel, so this is for noise-sensitive areas that want a bit more load, not for true heavy haulage. Rigid means it tracks straight. It serves from -45 to 180°F.

Ideal applications

• Quiet carts needing the top of the soft-rubber load range
• Stainless wash-down rigs in noise-sensitive clinical areas
• Straight-tracking rear corners under slower, heavier pushing

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

Pairs with: the flat-grey roller swivel 49MI42V-02 up front so the cart steers under load.
