Application guide — sizing, models and mounting advice from the manufacturer
A fixture table is only as good as its plane. If the top twists between setups, every jig you build on it inherits the error. Leveling casters let you move the table between cells and then put it back onto a flat, repeatable plane — every time, without shimming.
The pad lifts the wheels clear, so the table stops moving on its own and the top plane stays where you set it. Moving the table does not mean re-shimming it from scratch.
Factory floors slope towards drains and vary between pours. Independent pad adjustment lets you take that out at the table instead of fighting it with steel shims.
A fixture table that can be pushed to the weldment saves a crane lift and keeps a bay clear for the next job.
Shims under a table leg are a permanent maintenance item: they compress, they get kicked out, and they do not stop the table creeping. A threaded pad does not move once it is wound down.
Fixture tables are usually heavier than they look, because the top is a thick plate and the base is a fabricated steel frame. Divide the total weight by the number of casters and add 30–50%. A 2,000 kg modular table on six casters is 333 kg each — so specify 500 kg (DC-80F). A 4,000 kg table on six casters is 667 kg each, so step up to DC-100F at 750 kg. If the table is a long rail-mounted type with load concentrated at one end, size the end casters for the worst case, not the average.
| Model | Per caster | Mounting | Why it suits |
|---|---|---|---|
| DC-80F | 500 kg (1,100 lb) | Top plate | Mid-size fixture tables; the most common choice |
| DC-100F | 750 kg (1,655 lb) | Top plate | Heavy modular tables with thick plate tops |
| DC-120S | 1,000 kg (2,205 lb) | Threaded stem M16 | Where the frame already has threaded sockets and you want to avoid drilling |
| DCT-80 | 1,100 kg (2,425 lb) | Top plate | Low-profile mounting on very heavy fixture bases |
| DC-150F | 1,500 kg (3,305 lb) | Top plate | Extreme duty tables and heavy weldments |
Nylon is the default for a fixture shop: hard, low rolling resistance, unaffected by cutting fluid and resistant to swarf. Polyurethane if the table shares a floor with assembly or inspection and noise matters. Avoid soft rubber here — a heavy table on soft wheels feels unstable the moment you push it, and the tread takes a set under a static load.
The casters hold the table on four rigid feet so it cannot rock or creep, and each pad adjusts independently so you can take out floor slope. Whether the top is flat enough for your tolerance also depends on the table itself and how level you set it — use a precision level and check after every move.
Four is normal. Six or more is common on long tables, but remember that extra casters in the middle rarely share load evenly — it is usually better to fit four larger casters than six smaller ones.
Send us the plate dimensions and hole spacing you need, or the current caster you are replacing, and we will tell you which model matches. We can also supply a custom plate or stem for OEM runs.
Yes — STEP and IGES models, 2D drawings and dimension sheets are available. Request them through the CAD drawings page and we will send the files once we have confirmed your mounting.
Tell us the equipment weight, how many casters you plan to fit, the mounting you have and the floor it runs on, and we will come back with a model, a price and a lead time. Need the geometry first? Request the 2D drawing and 3D model and we will send them once your mounting is confirmed. If you are still choosing, the leveling caster buyer’s guide walks through load calculation and materials, and the applications index lists every scenario we build for. Factory profile, certifications and commercial terms are on the leveling caster manufacturer in China page, with quantities, MOQ and payment terms on the wholesale & OEM terms page.
