Hello everyone,
I have a somewhat specific request and hope there are people here with experience: Does anyone have replacement wheels or compatible casters for older KALLAX models from IKEA?
Specifically, I’m looking for the wheels attached to the bottom of the older KALLAX shelves, which unfortunately are no longer available from IKEA. The standard wheels for newer models do not fit without significant modifications, and I want to make the shelves mobile while keeping them as close to the original design and as stable as possible.
Has anyone found a source, alternative, or perhaps their own solution that works with little effort and can support the weight of fully loaded shelves? I look forward to your tips and experiences!

Hello Dapu1,
From my experience, the following approach works well when replacing older KALLAX casters:
1. First, accurately measure the old casters (diameter, mounting holes, height of the caster).
2. Then search hardware stores or online shops for replacement casters with matching screw dimensions.
3. If the holes or mounting types do not match, create small adapters from MDF or plywood and attach them to the shelving unit with screws.
4. The adapter plate is necessary because many new casters use different mounting dimensions.
As far as I know, ready-made adapters are not available, so DIY is usually the quickest solution.
Important: Measure the load capacity beforehand, as KALLAX shelves can become too heavy when fully loaded.
For verification, I tested the casters after installation using a luggage scale to avoid potential overload.
If you want, I can also provide measurements and sources.

Good morning,
I would like to provide a more detailed explanation regarding replacement casters for older KALLAX models:
The main challenge lies in the mounting technology. Older models often use an Allen screw with a specific thread size and a flat, rectangular mounting plate, whereas newer models mostly use round threads or completely different mounting brackets.
I recommend first measuring the mounting plate: length, width, hole spacing, and the depth of the recess.
After that, you can try to find industrial furniture casters with similar dimensions, preferably with a ball-bearing axle for smooth rolling.
Using an adapter plate is often the best solution. This adapter plate can be made from plywood or HDF, cut to size, and drilled precisely.
When designing, also consider that the casters should not add too much height, otherwise the overall shelving height will change significantly.
Finally, if you want to stay true to the original, you often have no choice but to use used original casters, as industrial casters usually differ visually.
Do you already have more specific information, such as the model number or pictures of the old mounting? That would greatly simplify the search.

Unfortunately, I cannot post pictures, but the model is likely from the first KALLAX generation around 2012. The casters are attached with a rectangular metal plate fixed by four screws to the bottom shelf. The screw spacing is approximately 5cm x 1.5cm (2 inches x 0.6 inches). The casters have a diameter of about 4.5cm (1.8 inches).
The casters themselves have a short threaded stem that screws into this plate.
I have already checked some replacement casters at the hardware store regarding diameter and load capacity, but they failed due to the mounting system. Without an adapter plate and modified screws, it won’t work.
Can someone please provide information on the recommended load ratings and suitable materials for the adapter?

Can someone please provide more details about the recommended load ratings and suitable materials for the adapters?You should definitely assume a load of at least 50 kg (110 lbs) per caster. A fully loaded KALLAX shelf can easily exceed 200 kg (440 lbs), especially when storing heavy books or binders.
For the adapter material, plywood or multiplex sheets with a thickness of 15-18 mm (0.6-0.7 inches) are ideal because they are stable, resist warping, and are easy to work with. MDF would be problematic under higher humidity or load.
For the screws used with the adapters and casters, I would recommend using at least M6 size to ensure sufficient stability.

If you’re building an adapter, make sure to securely fasten the threaded insert in the wood; otherwise, it may loosen over time and the shelving unit could become unstable.
Using a washer between the caster and the adapter plate also improves stability and protects the material.
If someone provides a manufacturer’s part number, I can check whether I still have the parts in stock 🙂

For those who care about aesthetics: black furniture casters usually match black KALLAX shelves better. There are even casters with plastic caps that cover the screw, significantly enhancing the overall look.
I’m curious if anyone else here will share their DIY solution :-)
