Low-profile stem casters deliver high capacity in a small form factor thanks to a shorter offset and lower overall height. The 3-inch O3 Series supports up to 500 pounds per caster while staying under 4 inches tall. Wide polyolefin or nylon wheels roll smoothly and resist chemicals, water, and wear. Roller bearings and zinc-plated double ball raceways ensure durable, corrosion-resistant swiveling under heavy loads. They are offered in stem installs.

Ideal for tight spaces like medical carts, server racks, and lab benches, these casters combine mobility with rock-solid stability. The compact design maximizes load capacity without sacrificing performance. Polyolefin or nylon tread handles harsh environments, while the short offset centers weight directly under the stem for superior strength. Install fast and move gear with confidence; big power fits where space is limited.
