The below capacity ranges indicate the working (dynamic) load that each caster will support. A safety factor should be included in your formula to determine your required load rating per caster.
W/(C-1)=R W is total weight needed to move. C is total number of casters required. R is ideal load rating, with safety factor built in. Divide the total load weight by one less caster than you will use to safely determine load rating.
Plate dimensions shown are overall mounting plate size. When replacing existing casters, select the closest plate size and verify bolt-hole compatibility. BHP = Bolt Hole Pattern, shown under each plate.

How to Choose Chair Casters
1. Match the Stem Type First
90 percent of U.S. office chairs use a 7/16-inch grip-neck stem with a smooth shaft and small ring near the top. The caster press-fits into the chair leg socket. Verify your existing caster has the same stem before ordering. If your chair has a threaded stem instead, you need a threaded stem caster.
2. Wheel Material for Your Floor
Hardwood, tile, polished concrete: soft TPR rubber or polyurethane to avoid scratching. Carpet: hard nylon for easier rolling. Mixed floors: polyurethane is the universal default.
3. Wheel Diameter for Comfort
Larger 75mm (3") wheels roll easier and clear larger floor transitions. Smaller 50mm wheels are quieter and fit lower-profile chairs. 60mm is the sweet spot for most office and dining chairs.
4. Self-Braking for Standing Desks
Self-braking casters lock automatically when the chair is loaded (someone sits down). Released when the chair is empty. Critical for standing-desk users who want the chair to stay put when stepping away.

Frequently Asked Questions
Will these fit my office chair?
Yes if your chair uses the standard 7/16-inch grip-neck stem — about 90 percent of U.S. office chairs do (Herman Miller, Steelcase, Haworth, Hon, IKEA, Costco, Staples). Check your existing caster's stem: smooth shaft with grip ring = these fit.
Are these safe for hardwood floors?
Yes — choose polyurethane or soft TPR rubber wheels for hardwood. Avoid hard nylon (designed for carpet). Polyurethane is non-marking and quiet on hardwood, tile, and laminate.
What's the difference between hard and soft wheels?
Hard nylon wheels roll easier on carpet but can damage hardwood. Soft TPR/polyurethane wheels are gentle on hard floors (hardwood, tile, laminate) but harder to roll on plush carpet. Match the wheel hardness to your floor type.
Do chair casters come in sets?
Yes — office chair caster sets of 5 (one per leg of a standard 5-leg chair base) are the most common. We also stock sets of 4 for dining chairs and individual replacements.
How do I replace chair casters?
Pull the old caster straight out of the chair leg (firm pull, may need a rocking motion). Push the new caster into the socket until it seats fully (you'll feel a click). No tools required. Total time: 30 seconds per caster.
What are self-braking chair casters?
Self-braking (also called weight-activated locking) casters lock when the chair is loaded (someone sits) and unlock when empty. Critical for standing-desk users who want the chair to stay put when stepping away.
Will these scratch my floor?
Polyurethane and TPR rubber casters are non-marking and floor-safe. Hard nylon can scratch hardwood — only use on carpet. Verify the product description says "non-marking" or "floor safe" before installing on hardwood.
What about gaming chairs?
Most gaming chairs use the same 7/16-inch grip-neck stem as office chairs. Verify by checking the existing caster — if it pulls straight out without unscrewing, it's grip-neck. Replace with same-type casters.
How many do I need to order?
Standard 5-leg office chair: 5 casters (we sell as sets of 5). 4-leg dining chair: 4 casters. Bar stool: usually 5. Some heavy-duty office chairs have 6 legs.
How fast do chair casters ship?
99 percent of orders ship same or next business day from our Mansfield, TX facility via FedEx Ground or USPS for small orders. Cutoff 2pm Central.
