50mm (2") Office Chair Caster

This listing is for one (1) piece of our 50mm or 2" diameter Twin Wheel Chair Caster. These casters are made to replace chair casters but can also be used on Dinette Chairs, Office Chairs, Home and Office Equipment, Furniture, and Store Display Stand Fixtures. The Nylon Twin Wheels are easy rolling and non-marking, great for all floor types including wood, vinyl, tile, carpet, cement, and more. The load capacity per Chair Caster is 90 lbs each meaning that a complete set of 5 Chair casters can support weight up to 450 lbs if your chair is able to support that much weight. You will need to check your chairs manual or specifications to see if the chair is capable of handling this much weight. Use the capacity of the chair or casters depending on which item can handle less weight to be safe. Grip Ring stem casters are extremely easy to remove and install on your chairs. Simply remove the old chair casters by pulling, popping, or prying the old ones out. Usually a good pull and the casters should pop out. To install, simple press in the grip ring stem directly into the hole until the casters sit flush on the base of the casters raceway or bottom of stem.

Frequently Asked Questions

What is the load capacity of this caster?+

This 2" Nylon Twin Wheel Grip Ring Stem Caster – 90 lb is rated to 90 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.

What wheel does this caster use?+

This caster runs a Nylon wheel. Nylon resists chemicals and moisture and carries high loads, which suits washdown and wet environments.

How does this caster mount to my equipment?+

This caster uses a Grip Ring Stem mount (7/16" x 7/8" stem). Stem casters press or thread into a socket - verify the stem diameter and length match your existing setup before ordering.

What temperature range can this caster handle?+

Rated for -40°F to 250°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.).

What floors and applications is it best for?+

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

What is the overall mounted height?+

The overall height (floor to top of plate or stem) is 2-3/8". Account for it when checking equipment clearance, dock height, and ergonomic working height.

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).
