Pressed Steel Braked Swivel Castors With Grey Rubber on Black Polypropylene Wheel

Available in 50mm, 75mm & 100mm  |  4-Hole Pressed Steel Top Plate  |  Dispatched from UK Stock


These pressed steel braked swivel castors are a reliable, floor-friendly mobility solution for a wide range of indoor applications. Each castor features a grey rubber tread bonded to a black polypropylene wheel core, mounted on a full 360-degree swivel head with an integrated foot-operated brake. The pressed steel top plate provides a secure, bolt-on fixing point compatible with standard furniture and equipment frames.

Designed for shop fitting, office furniture, light industrial trolleys, retail display units, and general material handling, these castors combine smooth, quiet rolling with the ability to lock firmly in position at the press of a foot. Available in three wheel diameters — 50mm, 75mm, and 100mm — each size carries a different load rating, allowing you to select the right castor for your specific application. All three share the same 60mm x 60mm top plate footprint for straightforward interchangeability.

* Load capacities are stated per individual castor. To calculate the minimum combined rating required, divide the total loaded weight of your equipment by the number of castors fitted and ensure each castor's rated capacity exceeds that figure. Always apply an appropriate safety margin.

50mm Braked Swivel Castor — Grey Rubber on Black Polypropylene Wheel — 60kg Load Capacity

4-Hole Pressed Steel Top Plate  |  Total Height: 72mm  |  Swivel Radius: 80mm

The 50mm braked swivel castor is the most compact option in this range, making it the natural choice for lower-profile furniture, lightweight trolleys, and shop display units where ground clearance is limited. Its grey rubber tread rolls quietly across hard floors and smooth tiles without marking, while the foot-operated brake locks the wheel and swivel head firmly in place whenever the unit needs to remain stationary. At 72mm total height, it integrates neatly beneath standard furniture frames and retail fixtures.

75mm Braked Swivel Castor — Grey Rubber on Black Polypropylene Wheel — 70kg Load Capacity

4-Hole Pressed Steel Top Plate  |  Total Height: 100mm  |  Swivel Radius: 92mm

The 75mm braked swivel castor sits at the mid-point of this range, offering a balanced combination of manoeuvrability and load-bearing capability. With a 70kg per-castor rating and a 100mm total height, it is well suited to medium-weight equipment that needs to be moved regularly but must remain firmly locked when in use. The wider 92mm swivel radius gives this size a particularly smooth, arc-free turning action, making it easy to navigate around corners and through doorways.

100mm Braked Swivel Castor — Grey Rubber on Black Polypropylene Wheel — 80kg Load Capacity

4-Hole Pressed Steel Top Plate  |  Total Height: 122mm  |  Swivel Radius: 83mm

The 100mm braked swivel castor is the largest and most capable option in this range, designed for heavier loads and applications where a taller overall height is required. With an 80kg per-castor rating, a set of four can support up to 240kg — making this size appropriate for loaded trolleys, heavier retail fixtures, and industrial support equipment. The larger wheel diameter also rolls more easily over minor floor imperfections and threshold strips, reducing the effort required to move loaded equipment across busy working environments.

How do I choose the right castor size for my application?
Start by calculating the total loaded weight of your equipment, then divide that figure by the number of castors you intend to fit — typically four. The result is the minimum load rating required per castor. Choose the next size up to allow a safety margin. For low-profile furniture or display units, the 50mm (60kg) option is ideal. For medium-weight trolleys and shelving, the 75mm (70kg) is the most versatile choice. For heavier loaded equipment or where a taller overall height is needed, the 100mm (80kg) provides the greatest capacity and rolls most easily over uneven floor surfaces.
Will these castors mark or damage hard floors?
No. The grey rubber tread is a non-marking compound, meaning it will not leave scuff marks or black streaks on hard floors including wood, laminate, vinyl, ceramic tile, and polished concrete. The rubber tread also absorbs minor vibration and rolls quietly, making these castors well suited to retail, office, and hospitality environments where floor appearance and noise levels matter.
How does the brake mechanism work, and does it lock the swivel as well as the wheel?
The brake is a foot-operated lever positioned at the base of the castor housing. Pressing it down with your foot engages a locking mechanism that simultaneously prevents the wheel from rotating and locks the swivel head, stopping the castor from turning in any direction. To release, simply lift the lever with your foot. This dual-lock action keeps equipment firmly in position on flat surfaces and is particularly useful in busy environments where accidental movement could be a hazard.
What fixings do I need, and will these castors fit my existing equipment?
All three sizes share the same 60mm x 60mm pressed steel top plate with four fixing holes of 6mm diameter. The hole centres are provided at two spacings — 48mm and 38mm — in both length and width directions, which means the plate is compatible with a wide range of standard furniture and equipment frames. You will need four M6 bolts, washers, and nuts (or self-tapping screws into timber) to secure each castor. If your existing equipment uses a different plate size or stem fitting, please check the dimensions carefully before ordering.
All castors are dispatched from UK stock and are ready for immediate despatch. Load capacities stated are per individual castor. Always ensure the combined load rating of your chosen castors exceeds the maximum loaded weight of your equipment, with an appropriate safety margin applied. For sets of four castors, multiply the individual load rating by four to obtain the maximum combined capacity.
