Frequently Asked Questions

What is the load capacity of this wheel?+

This 3310 Cast Semi-Steel Three Wheel Dolly 3" Phenolic Wheels – 750 lb is rated to 750 lbs per wheel. Divide the total load across the number of wheels in your rig and keep working loads within about 75-80% of the rating for continuous use.

What wheel material is this, and where does it perform best?+

This is a Phenolic wheel. Phenolic carries high loads on smooth, hard floors and tolerates heat, but transmits more shock than an elastomer tread.

What are the wheel dimensions and bore?+

3". Verify your axle diameter and hub/bore length against your existing wheel before ordering.

Can this wheel be supplied in a caster rig?+

Yes. Most wheels can be paired with a swivel or rigid rig to build a complete caster. Tell us your mount and load and we will spec the rig - request it on our bulk pricing page.

What temperature range is it rated for?+

Rated for Up to 250°F. Operating outside the rated range can shorten wheel life and reduce capacity.

How do I order, and what are the terms?+

We accept purchase orders and offer Net 30 on approved accounts, ACH, and all major cards, plus tax-exempt ordering with a resale or exemption certificate. Volume discounts apply automatically; request a bulk quote for large or recurring orders. Stock items carry a 30-day return policy in unused condition (made-to-order items are non-returnable once production starts).
