E.r. Wagner 3F09B4B27000103 Swivel Caster 4 in 275 Lb

Product Description

The E.R. WAGNER 3F09B4B27000103 is a stem-mount swivel caster built for mobile equipment and material-handling applications requiring a compact, load-bearing wheel assembly. The caster features a 4-inch diameter polyolefin wheel that is 1-3/8 inches wide, with an overall assembly height of 5 inches. A Delrin bearing supports smooth rotation under load, and the zinc-finished hardware resists corrosion in light-duty service environments. Load capacity is rated at 275 pounds. The friction stem measures 7/16 inch in diameter and 1-29/32 inches in length, providing a press-fit mount into compatible stem sockets. Hardened, heat-treated construction adds durability to the swivel mechanism.

This caster is suited for use on carpeted surfaces and is appropriate for light commercial or industrial carts, racks, and mobile furniture where a swivel wheel provides directional control. The polyolefin wheel material is gentle on floor coverings and performs well in environments where hard rubber or metal wheels would cause surface damage. Installation is straightforward for maintenance technicians and equipment assemblers working with standard stem-socket caster mounts. The NSF listing makes this caster acceptable for food-service or food-adjacent equipment applications where sanitation standards apply.

Key Features

• 4-inch diameter polyolefin wheel rated for 275 pounds load capacity
• Delrin bearing provides smooth, low-friction swivel rotation
• Friction stem mount: 7/16 inch diameter x 1-29/32 inches length
• Hardened and heat-treated swivel construction for extended service life
• Zinc finish on metal components for corrosion resistance

Compatibility

Designed for use with equipment accepting a 7/16-inch friction stem socket mount. Rated for carpeted surface applications. Verify stem-socket bore diameter and depth before installation to confirm fitment.

Installation Notes

Installation is performed by maintenance technicians or equipment assemblers. Press the friction stem firmly into the receiving socket until fully seated - no tools beyond hand pressure or a rubber mallet are typically required. Confirm the socket bore matches the 7/16-inch stem diameter before pressing to avoid damaging the socket. Inspect swivel action and load rating before returning equipment to service.
