E.r. Wagner 3F09B4B25000101 Swivel Caster 275 Lb

Product Description

The E.R. WAGNER 3F09B4B25000101 is a stem mount swivel caster designed for light-to-medium duty rolling applications. It features a 4-inch diameter polyurethane wheel with a 1-1/4-inch wide tread, a Delrin bearing, and a zinc-finished hardened, heat-treated construction. The overall assembly height is 5 inches, and mounting is accomplished via a 7/16-inch by 1-3/8-inch friction stem. With a 275-pound load capacity, this caster is suited for use on carts, workbenches, and mobile equipment where smooth, controlled movement is required. Installation is typically handled by maintenance technicians or equipment fabricators.

This caster is rated for use on carpeted surfaces, making it a practical choice for facilities, shops, and light industrial environments where carts or portable equipment must roll across carpet without damaging floor coverings or losing maneuverability. The polyurethane wheel offers good resistance to wear and provides a non-marking, relatively quiet ride. The friction stem mount allows direct installation into pre-drilled socket holes or stem receivers on standard caster-mount frames and equipment bases without additional hardware.

Key Features

• 4-inch diameter polyurethane wheel rated for carpeted surface applications
• 275-pound load capacity per caster
• Delrin bearing for smooth, low-friction swivel rotation
• 7/16-inch by 1-3/8-inch friction stem for tool-free or simple press-fit installation
• Zinc-finished, hardened and heat-treated construction for corrosion resistance and durability
• 5-inch overall assembly height (OAH) with 1-1/4-inch wide wheel tread

Compatibility

Designed as an OEM-style replacement or new-install stem mount swivel caster for carts, benches, and mobile equipment frames that accept a 7/16-inch friction stem and require a 4-inch wheel with a 5-inch overall height.

Installation Notes

Installation is performed by inserting the friction stem into the receiving socket on the equipment base. Ensure the socket bore matches the 7/16-inch stem diameter before installation. Power down or de-energize any motorized equipment before performing caster replacement or installation. Verify the total load per caster does not exceed the 275-pound rating when calculating caster quantity for the application.
