Application guide — sizing, models and mounting advice from the manufacturer
A welding table has to be dead flat and rock solid while you are striking an arc — and movable the moment the shop layout changes. A leveling caster does both. Roll the table into position, wind each pad down until it takes the load and lifts the wheels off the floor, and the table is standing on four rigid feet instead of four springy wheels.
A table on four plain casters rocks as you lean into a weld, because wheels are never perfectly matched to the floor. The leveling pad bypasses the wheel completely and puts the load into a solid foot.
Any twist in the table shows up in the part. Because every pad adjusts independently, you can level the top on an uneven shop floor with a spirit level, and it stays there between jobs.
No pallet truck, no crane, no cleared aisle. Useful when a table has to move between bays or be pushed out of the way for a large weldment.
Wheels left under a static load for months take a set and develop flat spots. Because the pad carries the weight, the wheels stay round and the table still rolls smoothly a year later.
Work out the load per caster first — it decides everything else. Divide the total table weight by the number of casters, then add 30–50% for uneven weight distribution and the operator leaning on one corner. A 1,200 kg table on four casters needs at least 300 kg per caster, so specify 400–500 kg. A 3,000 kg fabrication table on four casters needs 750–1,000 kg per caster. If the table is long and carries a heavy fixture at one end, go up a size rather than adding casters in the middle — the centre casters will not share load evenly.
| Model | Per caster | Mounting | Why it suits |
|---|---|---|---|
| DC-80F | 500 kg (1,100 lb) | Top plate | Small and mid-size weld tables; the workhorse size for a one- or two-man shop |
| DC-100F | 750 kg (1,655 lb) | Top plate | Large fabrication tables and heavy steel tops; 73 mm wheel rolls over swarf |
| DC-100FH | 750 kg (1,655 lb) | Thick top plate | Same rating as DC-100F with a thicker plate for high-torque bolting |
| DCT-80 | 1,100 kg (2,425 lb) | Top plate | Very heavy tables where a low mounting height matters |
| DC-150F | 1,500 kg (3,305 lb) | Top plate | Extreme duty tables, die carts and large weldments; 92 mm wheel |
For a welding shop, nylon (PA6) is usually the right wheel: it rolls easily under load, resists oil and metal swarf, and does not mark the floor. Polyurethane is quieter and kinder to epoxy floors but costs more. Rubber gives the best grip but wears fastest on grit. One honest caveat: welding spatter damages every caster wheel eventually, so keep the wheels out of the spatter zone, or accept that they are a consumable. The bracket on our DC-F range is die-cast ADC12 aluminium — noticeably lighter than cast iron at the same rating, so more of the rated capacity goes into holding your table up instead of holding the caster itself up.
Yes, in most cases. You need a flat surface to bolt the top plate to and enough material to take four bolts per caster. Send us a photo of the leg or frame with the dimensions and we will tell you honestly whether it will hold — and if it will not, what to add.
Replace the plain casters with leveling casters and wind the pads down until the wheels come off the floor. The table then stands on four fixed feet and cannot rock, because the wheels are no longer touching the ground.
750 kg per caster is more than you need. 1,200 kg over four casters is 300 kg each, and with a 50% margin that is 450 kg — so DC-80F at 500 kg is the right size. Choose DC-100F at 750 kg if the table is long, top-heavy or likely to grow.
Yes. Tell us the model you are considering and we will send the dimension sheet, 2D CAD drawing and 3D model so your fabricator can drill before assembly.
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.
