PRODUCT CODE: S40-S-820-DUA
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.
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.
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.
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.
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.
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.
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.
