E.r. Wagner 3F09B9B27000101 Swivel Caster 250 Lb

Product Description

The E.R. WAGNER 3F09B9B27000101 is a stem mount swivel caster designed for light-to-medium duty material handling applications. It features a 3.5-inch diameter polyolefin wheel that is 1.25 inches wide and rides on a Delrin bearing for smooth, low-friction rotation. The overall assembly height is 4.5 inches. A 7/16-inch diameter friction stem, 1.375 inches long, provides the mounting interface. The zinc-finished hardware and hardened, heat-treated construction give the unit durability in regular service. Licensed trades and facilities maintenance personnel commonly install this type of caster on carts, equipment bases, and mobile workstations.

This caster is rated for carpeted surfaces and carries an NSF certification, making it suitable for use in food service, healthcare, and commercial facility environments where sanitation standards apply. The polyolefin wheel compound resists moisture and common cleaning agents without marking finished floors. The swivel head allows full 360-degree directional movement, making it appropriate for equipment that requires frequent repositioning. Typical applications include utility carts, light shelving units, and service equipment in commercial or institutional settings.

Installation Notes

Friction stem casters are installed by pressing the stem directly into a pre-drilled or factory-installed stem socket in the equipment base - no tools are typically required, but a rubber mallet may help seat the stem fully. Verify the socket inner diameter matches the 7/16-inch stem before installation to ensure a secure fit. Inspect the stem socket for wear or damage before installing a replacement caster. Confirm the load rating of all casters on the assembly meets or exceeds the total loaded weight of the equipment.
