Swivel Stem Caster 4 in 350 lb

This ZORO SELECT swivel stem caster fits wheelbarrows, carts and similar yard equipment that require a 4 inch wheel. It carries a 350 lb load rating and mounts on a 7/16 in by 1-29/32 in friction-ring stem. The steel frame has a zinc-plated finish and the polyurethane tread is non-marking.

Thermals noise and power draw

As a passive wheel component the caster generates no heat, noise or electrical draw during normal movement. The Delrin bearing and polyurethane tread roll quietly over hard surfaces without vibration. No power source or cooling is involved in its operation.

Sustained load behaviour

Under continuous loads up to 350 lb the polyurethane tread resists flat-spotting and the zinc-plated frame maintains structural integrity. The friction-ring stem holds securely in its socket during prolonged use. California Proposition 65 warnings apply for chemical content.

Highlights

Questions about this item

How do I install the 7/16 in stem with its friction ring, and what step is often missed?

Press the stem into the mounting hole until the friction ring snaps into the groove; the step people skip is verifying the ring is fully seated so the caster cannot pull out.

What maintenance or replacement will this caster need over time?

The Delrin bearing runs without lubrication, so only the polyurethane tread wears; replace the caster when the wheel no longer rolls smoothly or shows flat spots.

What limit appears first when the caster runs continuously at its 350 lb rating?

Heat buildup in the polyurethane tread is the first limit; sustained loads at the 350 lb rating can soften the material and accelerate wear.
