350 lb Swivel Stem Caster

This ZORO SELECT stem caster carries a 350 lb load rating and fits wheelbarrows, carts and similar yard equipment. The 3 in polyolefin wheel is non‑marking and mounted in a zinc‑plated steel frame. A 3/4‑10 threaded stem measuring 1 in long secures the caster in place. The unit stands 3 7/8 in tall at its mounting height.

Replaces fixed or lower‑rated casters

Swapping a rigid wheel or a caster rated below 300 lb for this 350 lb swivel model adds steering freedom and a higher weight ceiling. The upgrade is worthwhile when the existing hardware cannot turn sharply or when loads regularly approach the old limit. The polyolefin tread resists flat‑spotting better than many softer rubber wheels.

Sustained load behaviour

Under continuous weight the polyolefin wheel maintains its shape and the ball bearing swivel keeps rotating without binding. The zinc‑plated frame resists corrosion during long outdoor exposure. The non‑marking tread prevents stains on paved surfaces even after prolonged stationary periods.

Questions about this item

What stem size fits the 3 in swivel caster?

The caster uses a 3/4 in.-10 threaded stem that is 1 in long, so the mounting hole must match that thread and depth.

How do I install the threaded stem caster without stripping the threads?

Thread the stem straight into the tapped hole by hand until snug, then tighten with a wrench on the stem flats — forcing it crooked is the common mistake.

When should I replace the polyolefin wheel on this 350 lb caster?

Replace the wheel when the tread shows flat spots, cracks, or no longer rolls smoothly, since the polyolefin material cannot be repaired.
