The E.R. WAGNER 3F09B9D04000101 is a stem mount swivel caster built for hard surface applications requiring controlled mobility and a moderate load rating. The wheel measures 3.5 inches in diameter and 1.25 inches wide, with an overall assembly height of 4.5 inches. It carries a rated capacity of 155 pounds and rolls on a soft rubber wheel that protects finished floors and hard surfaces from scuffing or damage. The Delrin bearing provides smooth, low-friction rotation suited to frequent repositioning. The zinc-finished yoke uses hardened, heat-treated construction for durability under repeated load cycles. This caster is a standard choice for light-duty equipment carts, workbenches, and mobile fixtures in shop, warehouse, and commercial environments.
This caster is designed for use on hard floor surfaces including concrete, tile, and sealed wood. The friction stem mount - 7/16 inch diameter by 1.375 inches long - installs directly into pre-drilled stem sockets without fasteners, making it well-suited for furniture, utility carts, and light commercial equipment where tool-free wheel replacement is preferred. The swivel action provides full-circle rotation for tight maneuvering in confined spaces. It is appropriate for both shop and light industrial settings where a 155-pound-per-caster load rating meets the application requirement.
Designed as an OEM-style replacement or direct-fit caster for equipment using a 7/16 inch friction stem socket, rated for hard surface use at up to 155 pounds per caster.
Friction stem casters are installed by pressing or tapping the stem into a matching stem socket on the equipment leg or frame - no tools or fasteners are required in most applications. Verify the socket inside diameter matches the 7/16 inch stem before installation. Ensure the equipment is fully supported and stationary before swapping casters. Do not exceed the rated 155-pound per-caster load capacity in service.
