8"x 2" Stainless Steel Top Plate Swivel Caster with Performa Rubber (Round/Conductive) Wheel - D4.08109.555 COND SS

About This Caster - D4.08109.555 COND SS

Choose this 8-inch Defender D4 swivel when a steering cart must drain static in an ESD-sensitive or flammable area and roll easily over the roughest floors.

The swivel head guides the cart through tight bays, with a 6.375-inch swivel radius to allow, while the conductive round-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. Its round profile keeps rolling resistance low and the soft rubber rolls quietly, though the conductive compound can mark a light surface. The tallest 8-inch wheel clears the widest cracks and big obstacles, and the pedestal precision ball bearing keeps wheel and swivel turning smoothly, on a stainless steel frame for corrosion. It serves from -45 to 180°F.

Ideal applications

• 8-inch ESD-sensitive carts that steer, drain static, and roll over obstacles
• Flammable or solvent bays needing low-resistance static control
• Round-tread front corners that clear the biggest obstacles

Verify the conductive resistance spec and that the wheel and swivel both carry the path to ground, plus the 6.375-inch swivel radius, before ordering.

Pairs with: matching conductive Defender D4 casters on all four corners so the whole cart stays grounded, from the Colson collection.

Wrong fit? No static concern, just a quiet non-marking swivel? See the 8-inch grey round-tread precision-ball swivel D4.08109.555 in the Colson collection.
