S40 Series Heavy Duty Kingpinless Swivel Caster – 8" × 2" Donut Polyurethane on Aluminum – 2,000 lb Capacity


This S40 Series caster pairs a kingpinless swivel raceway (built for impact and abuse) with the most commonly spec’d ergonomic polyurethane-on-aluminum wheel used across manufacturing, automotive, and plant environments where reduced push/pull force, quiet rolling, and long service life matter.

Product Highlights

  • Swivel Design: Kingpinless for higher durability in shock-load, impact, and rough-floor environments
  • Wheel: 8" × 2" donut polyurethane tread on aluminum core for high capacity + smoother rolling
  • Capacity: 2,000 lb per caster (verify total capacity based on # of casters and load distribution)
  • Ergonomics: Polyurethane tread helps reduce push/pull effort versus hard steel/iron wheels on many floors
  • Debris Handling: Donut profile helps reject small debris and maintain roll performance in real-world plants
  • Noise: Quieter operation than metal wheels in many industrial settings
  • Bearings: Select bearing option for your speed, duty cycle, and floor conditions
  • Top Plate Options: Multiple plate sizes available to match equipment patterns
  • Common Uses: Carts, fixtures, racks, heavy assemblies, tow-line and plant material handling

Why Kingpinless Swivel?

Kingpinless casters are preferred in heavy-duty plants because they eliminate the kingpin failure point. This improves resistance to shock loads, side impacts, and continuous abuse that can loosen or deform traditional kingpin swivel assemblies over time.

Kingpinless benefits in plain terms
  • Higher impact tolerance: better for docks, thresholds, and rough concrete
  • Less swivel play over time: maintains tracking and handling longer
  • Better reliability under abuse: reduces “caster wobble” failure modes common in kingpin designs

Wheel Performance (Ergonomic Industrial Standard)

Polyurethane-on-aluminum is a widely used “workhorse” configuration for facilities that need industrial capacity without the noise and floor harshness of steel wheels. The donut tread profile is designed to keep rolling more consistently when floors are not perfectly clean.

What this wheel is best at
  • Reduced push/pull effort compared to hard metal wheels on many floors
  • Quiet rolling in production and assembly environments
  • High durability for continuous daily movement
  • Floor-friendlier than steel/iron wheels in many applications
How to spec the right plate size & bearing

Confirm your equipment’s bolt-hole pattern and required overall height before ordering. Choose bearing type based on duty cycle, speed, floor condition, and exposure (debris, washdown, chemicals). If you share your cart weight, load type, and floor conditions, we can recommend the best configuration.

Frequently Asked Questions

What does “2,000 lb capacity” mean in real use?

It is the rated capacity per caster under proper load distribution and typical operating conditions. Total system capacity depends on how many casters are used and how evenly the load is carried.

Why choose polyurethane-on-aluminum vs steel wheels?

Polyurethane wheels typically roll quieter and can reduce push/pull force while still handling heavy loads. Steel wheels can be loud and harsh on floors but may be preferred for extreme heat or certain chemical environments.

Is kingpinless worth it?

If your carts see impacts, rough floors, dock plates, thresholds, or continuous abuse, kingpinless is usually the more reliable long-term swivel design because it removes the kingpin as a failure point.

Frequently Asked Questions

What is the load capacity of this caster?+

This 8" x 2" Polyurethane on Aluminum Swivel Kingpinless Caster – 2,000 lb is rated to 2000 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 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. 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 caster. Swivel casters rotate 360 degrees for full maneuverability. 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 -20°F to 180°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 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 9-1/2". 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).
