4" Stainless Steel Caster w/ Performa Rubber (Flat/Conductive) Wheel - D4.04109.459 COND SS WB29

About This Caster - D4.04109.459 COND SS WB29

Reach for this 4-inch Defender D4 swivel when a heavier cart must both steer and drain static in an ESD-sensitive or flammable workspace.

The swivel guides the front of the cart through tight bays, with a 3.375-inch swivel radius to allow, while the roller bearing gives that swivel the highest capacity of the three bearings, carrying weight at a slow, controlled pace. The conductive flat-tread Performa wheel carries static charge from the cart down through the caster to ground, protecting electronics and reducing spark risk near solvents or dust. The flat profile gives a stable footprint, and the soft rubber rolls quietly and stays easy on floors, though the conductive compound can mark a light surface. The stainless steel frame suits wash-down duty. Soft rubber holds the load class modest, so static control leads. It serves from -45 to 180°F.

Ideal applications

• Heavier ESD-sensitive carts that must drain static while steering
• Flammable or solvent bays needing maneuverable static control under load
• Front steering corners with a stable conductive footprint

Verify the conductive resistance spec and that the wheel and swivel both carry the path to ground, plus the 3.375-inch swivel radius, before ordering.

Pairs with: matching conductive Defender D4 casters on all four corners so the loaded cart stays grounded, including the conductive roller rigid 49MI42GT-02.

Wrong fit? No static concern, just a quiet non-marking swivel? See the grey flat-tread roller swivel 49MI42V-02 in the Colson collection.
