Where the D4.04109.935-KW-BRK4-SS fits in your application

  • Hospital and medical equipment
  • Food processing carts (NSF compliant where applicable)
  • Polished concrete plant floors
  • Cleanroom and ESD-sensitive equipment
  • Office and lab cart applications
  • Quiet-roll material handling

Engineer Tip — Jordan Wilson

I spec Colson on standard-duty industrial carts where bearing life and quiet roll matter more than maximum capacity. The D4.04109.935-KW-BRK4-SS earns its place when smooth-roll quiet operation and floor protection are the controlling spec. Pair 4" on the steered axle with a matching rigid version on the trailing axle for true four-position cart kinematics. If your floor has expansion joints over 1/2" wide, step up to a larger wheel diameter.

FAQs

What does the Colson part number D4.04109.935-KW-BRK4-SS mean?

Colson encodes its part numbers by series, wheel material, wheel diameter, plate size, bearing type, and mount style. The D4.04109.935-KW-BRK4-SS is decoded by your CasterHQ engineer at order time — call us at 844-439-4335 for a full breakdown.

What is the load capacity of the D4.04109.935-KW-BRK4-SS?

700 lbs per caster dynamic. On a 4-caster cart with even load distribution and a 1.3x safety factor for moving loads, that yields the rated working capacity per cart.

Will the D4.04109.935-KW-BRK4-SS work on rough concrete?

Yes for cast iron and steel wheels. 4" diameter rolls over expansion joints and seams cleanly. For polished or epoxy floors, ask us about poly-on-iron or thermoplastic options.

Frequently Asked Questions

What is the load capacity of this caster?+

This Colson D4.04109.935-KW-BRK4-SS 4" x 2" K Solid Polyurethane Caster — 700 lb is rated to 700 lbs per caster. Size a set by dividing the total load by the number of casters, and for uneven floors assume 3 of 4 casters carry the load. Keep continuous-use loads within about 75-80% of the rating.

What wheel does this caster use?+

This caster runs a Solid Polyurethane wheel with a 2" tread width. Polyurethane protects finished floors, rolls quietly, and resists most chemicals while carrying heavy loads.

What plate size and bolt pattern does it use?+

This caster uses a top-plate mount with a 4" x 4-1/2" plate and a 3" x 3" bolt pattern. Measure your existing mounting holes before ordering; if you are replacing casters, match the bolt pattern - most standard patterns interchange across brands.

Is this a swivel or rigid caster, and how does the brake work?+

This is a Swivel with Total Lock Brake caster with a wheel brake. Swivel casters rotate 360 degrees for full maneuverability. The brake locks the wheel to hold the load in place. For most mobile equipment we recommend 2 swivel + 2 rigid, or 4 swivel with at least 2 brakes.

What temperature range can this caster handle?+

Rated for -40°F to 600°F. Operating outside the rated range can reduce wheel life and load capacity, so match it to your environment (wash-down, freezer, oven-adjacent, etc.).

What floors and applications is it best for?+

The Solid Polyurethane wheel performs best on smooth to semi-smooth floors including sealed concrete, tile, and epoxy. For non-marking or clean-environment needs, ask us about matching tread options.

What is the overall mounted height?+

The overall height (floor to top of plate or stem) is 5.63". Account for it when checking equipment clearance, dock height, and ergonomic working height.

How do I order, and what are the terms?+

We accept purchase orders and offer Net 30 on approved accounts, ACH, and all major cards, plus tax-exempt ordering with a resale or exemption certificate. Volume discounts apply automatically; request a bulk quote for large or recurring orders. Stock items carry a 30-day return policy in unused condition (made-to-order items are non-returnable once production starts).
