4" Stainless Steel Top Plate Rigid Caster with Maxim Nylon Glass filled Wheel - D4.04108.539 SS WB29

About This Caster - D4.04108.539 SS WB29

Reach for this 4-inch Defender D4 rigid when a chemical-area cart is loaded to the limit and pushed slowly.

This is the highest-capacity build in the Maxim glass-filled nylon line: the roller bearing carries the most weight of the three bearings offered, suited to slow, sustained pushing, and the Maxim wheel matches it with glass-fiber reinforcement that takes heavy point loads while resisting chemicals and moisture. The stainless steel frame holds up in corrosive, sprayed-down bays, and the rigid mount keeps the load tracking straight at the rear. Glass-filled nylon is hard with no cushioning, so it transmits floor shock and can mark a soft surface, making this a pure strength-and-capacity caster for hard floors. It serves from -20 to 180°F.

Ideal applications

• Maximum-load chemical-area carts pushed slowly down a line
• Stainless transfer rigs at the top of the nylon capacity range
• Straight-tracking rear corners under the heaviest sustained loads

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

Pairs with: the Maxim roller swivel 49XI42V-02 up front so the heavy cart steers.
