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
Rubber tread
- Cushions the load and soaks up vibration
- Quiet on most surfaces
- Copes with uneven floors, thresholds and outdoor use
- Good grip on smooth floors
- Takes more effort to push than nylon under heavy loads
- Oils and solvents shorten tyre life
Details & FAQs
Pressed Steel Swivel Castors With Grey Rubber on Black Polypropylene Wheel
Available in 50mm, 75mm & 100mm | 4-Hole Top Plate | UK Stock | Ready to Dispatch
These pressed steel swivel castors are fitted with a grey rubber tread bonded onto a black polypropylene wheel centre, delivering quiet, smooth-rolling mobility across hard floors and smooth surfaces. Designed for light-duty commercial and industrial use, they are mounted via a 4-hole pressed steel top plate that bolts directly to the underside of trolleys, furniture, shelving units, and equipment frames.
Available in three wheel diameters — 50mm, 75mm, and 100mm — each size offers a different load capacity and overall height, allowing you to select the right castor for your specific application. The plain bearing construction keeps maintenance minimal, while the rubber tread protects floor surfaces from marking and scuffing. All three options share the same 60mm x 60mm top plate footprint with dual hole-centre options, making them straightforward to fit across a wide range of standard equipment.

* Load capacities stated are per individual castor. For a set of 4, divide the total equipment weight by 4 to confirm each castor remains within its rated capacity. Always allow a safety margin.
50mm Swivel Castor — Grey Rubber on Black Polypropylene Wheel — 4-Hole Top Plate
60kg Load Capacity per Castor | 180kg Maximum Load (Set of 4)The 50mm swivel castor is the most compact option in this range, making it well suited to lighter equipment, small trolleys, and furniture where floor clearance is limited. Despite its modest wheel diameter, it delivers reliable rolling performance on smooth hard floors and offers a non-marking grey rubber tread that keeps surfaces scratch-free. The pressed steel top plate provides a rigid, stable mounting point that bolts securely to the underside of the equipment frame.

75mm Swivel Castor — Grey Rubber on Black Polypropylene Wheel — 4-Hole Top Plate
70kg Load Capacity per Castor | 210kg Maximum Load (Set of 4)The 75mm swivel castor sits in the middle of this range, offering a balanced combination of manoeuvrability and load-bearing capability. Its larger wheel diameter rolls more easily over minor floor irregularities compared to the 50mm option, and the increased swivel radius of 70mm allows for smooth directional changes even when the equipment is loaded. This size is a popular choice for medium-weight trolleys, mobile shelving, and institutional equipment across retail, logistics, and light industrial environments.

100mm Swivel Castor — Grey Rubber on Black Polypropylene Wheel — 4-Hole Top Plate
80kg Load Capacity per Castor | 240kg Maximum Load (Set of 4)The 100mm swivel castor is the largest and highest-capacity option in this range, providing the greatest ground clearance and the smoothest roll over uneven or slightly textured floor surfaces. With a total castor height of 122mm and a swivel radius of 83mm, it is well suited to larger trolleys, heavy-duty mobile equipment, and applications where the equipment needs to travel longer distances across a facility. The 80kg per-castor load rating supports a combined maximum of 240kg across a set of four, making it the preferred choice for more demanding light-to-medium duty tasks.
