Customer Questions

Is it possible to get ONE caster for a chair. 4 out of 5 are fine - one is broken. Nothing indicates that this can be done through you. If not is there anyone who sells them individually. September 16, 2016
Miles OnTimeSupplies.com

Master Caster does not offer single safety casters, but they sell them by the set of 4 or 5.  The main reason they do this is so the chair will sit evenly on the floor, and all casters will have the same "wear and tear."  Kind of like tires on a car.  Hope this makes sense.

Now the good news is that we have these casters in stock for same day shipping and your delivery will be there in 1-2 business days.  Plus we do offer a low flat rate shipping of $7.95 and if you order more than $75.00 we will provide FREE shipping!

I need to replace the casters on a used Ikea Verner office Chair. They are eating into my wood floors. I am not sure what size I need. The stem is 3/4" long. April 23, 2014
On Time Supplies Retailer

Hi Mike,

Thank you for your question about chair casters. I think we can help you.

First, we can narrow down wheel style. All wood floors require soft wheel casters. These won't damage your floor, and and prevent your chair from sliding around too much on the smooth surface.

Figuring out the right stem is a little trickier. The first thing to do is check out the chair base. Is it wood, metal, or wood clad (metal with a wood or simulated wood cover)? 

If your chair has a wooden base, you'll need W stems. You can order soft wheel W Stem Casters here

If your chair has a metal or wood clad base, you'll have to remove one of your current casters and measure the stem. The best way to measure the diameter is to wrap a string around the stem, then measure that length. Most stems have either a 7/16" or 3/8" diameter. After measuring the diameter, measure the length to get the proper stem type. 

C, K and B Master Caster Stems

If your current stem is longer than the options in the diagram, that's ok. You can use a stem shorter than your original. Only the diameters have to match.  

Hope this answers your question!


Does anyone make low rider casters for short people whose feet won't reach the floor in an office chair with standard casters? September 17, 2014
Frankye OnTimeSupplies.com

Low profile casters are not available. If you need to lower the height of your chair, try low-profile bell glides MAS70179 or MAS70178.

I was very happy with the website, product, and services. OnTimeSupplies.com had useful tools for the shopper so that I could understand the measurements, see the matching product and a description for use of the replacement wheels I purchased. I researched many websites trying to find replacement wheels and OnTimeSupplies.com offered everthing I needed to be a wise and precise shopper. They offered a set of 5 wheels for my special, dearly loved office chair. The wheels are a high quality and I will purchase from OnTimeSupplies.com again. Thanks so much for the quick delivery too.
