4" x 1-1/4" High-Temp Glass-Filled Nylon Swivel Caster – 350 lb | 7/16" x 1-3/8" Grip Ring Stem

This 4" x 1-1/4" High-Temp Glass-Filled Nylon Swivel Caster – 350 lb is rated to 350 lbs per caster. Size a set by dividing the total load by the number of casters, and for uneven floors assume 3 of 4 casters carry the load. Keep continuous-use loads within about 75-80% of the rating.

This caster runs a Nylon wheel with a 1-1/4" tread width. Nylon resists chemicals and moisture and carries high loads, which suits washdown and wet environments.

This caster uses a Grip Ring Stem mount (4" x 1-1/4" stem). Stem casters press or thread into a socket - verify the stem diameter and length match your existing setup before ordering.

This is a Swivel caster. Swivel casters rotate 360 degrees for full maneuverability. For most mobile equipment we recommend 2 swivel + 2 rigid, or 4 swivel with at least 2 brakes.

Rated for -45°F to 475°F. Operating outside the rated range can reduce wheel life and load capacity, so match it to your environment (wash-down, freezer, oven-adjacent, etc.).

The Nylon wheel performs best on smooth, hard industrial floors. For non-marking or clean-environment needs, ask us about matching tread options.

The overall height (floor to top of plate or stem) is 5-1/8". Account for it when checking equipment clearance, dock height, and ergonomic working height.
