Replacing an old castor? Measure between the centres of two fixing holes along the long edge, then across the short edge, and compare with the hole centres above. Allow the swivel radius as clear space around each castor so it can turn freely.
Load check
How we work it out: on a real floor one castor is often carrying little or nothing, so we share the weight across one fewer castor than you fit (with 3 castors, across all 3). Tick the box to add a 30% margin for rough use.
Floors & use
Nylon / polypropylene wheel
- Very easy to push, even when loaded
- Resists water, oil and many chemicals
- Hard-wearing and easy to wipe clean
- Best on smooth concrete and hard floors
- Noisier than rubber or polyurethane
- Hard tread can mark or damage soft and delicate floors
- Rolls poorly over debris and cables
Details & FAQs
Heavy Duty Low Profile Top Plate Castor
This compact 50mm heavy duty swivel castor carries up to 200kg per castor while standing only 71mm tall. A solid black nylon wheel on a ball bearing rolls easily under load, and the black finished pressed steel housing gives a neat, low profile look under machinery, cabinets and heavy furniture.
The 71 x 55mm top plate with four 6mm holes bolts flat under bases where space is tight, and the 55mm swivel radius lets the castor turn in a small footprint. Solid nylon will not flatten or split and shrugs off oil and most chemicals.
Why Choose This Castor
- ✓ 200kg load capacity per castor
- ✓ Low 71mm overall height
- ✓ Solid nylon wheel that resists flat spots, oil and chemicals
- ✓ Ball bearing for smooth rolling under load
- ✓ Black finished pressed steel housing
- ✓ Compact 71 x 55mm top plate and 55mm swivel radius
Load capacity is per castor. For a set of four, allow for uneven floors by planning on three castors carrying the load.
Where It Works Best
Machine bases, workbenches, heavy cabinets, server and equipment racks, low dollies and stage or display platforms that need a strong castor with a low fitted height. Best on smooth hard floors such as sealed concrete, vinyl and epoxy.
Frequently Asked Questions
How much weight can this castor carry?
Each castor is rated at 200kg. A set of four is best used for loads up to around 600kg, allowing for uneven floors.
How low is it?
The overall height from floor to top plate is 71mm, so fitted units stay close to the floor.
What size bolts do I need?
The 71 x 55mm top plate has four 6mm holes on 50 x 35mm centres, so M5 or M6 bolts are a good fit.
Will a nylon wheel mark my floor?
Nylon is a hard wheel that rolls easily and does not leave black marks, but it suits smooth hard floors best. For delicate floors a rubber or polyurethane wheel is quieter.
Is there a braked version?
Many users fit two swivel and two braked castors of the same size and height so the unit can be held in place.
