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

50mm Swivel Braked Castor Wheel — Grey Rubber on Polypropylene, 4-Hole Zinc-Plated Top Plate, 60kg Load Capacity
A compact, floor-friendly swivel castor fitted with a positive-locking brake mechanism and a grey rubber tread bonded to a polypropylene core. Designed for light-duty mobility applications where controlled movement and secure stationary positioning are equally important — including retail display units, office furniture, hospitality trolleys, and light workshop equipment.
This 50mm swivel braked castor combines a pressed steel, zinc-plated top plate with a smooth-rolling rubber wheel to deliver reliable, floor-safe mobility across a wide range of surfaces. The integrated brake engages directly on the wheel tread, locking the castor in place instantly — a practical requirement wherever equipment must remain stationary between uses. The grey rubber compound absorbs vibration and resists marking on hard floors, while the rigid polypropylene wheel centre keeps rolling resistance low and the overall unit weight minimal.
With a 60kg load rating per castor and a total height of 72mm, this unit is well suited to lighter equipment frames, trolleys, and furniture bases where a low-profile, non-marking solution is required. The four-hole top plate with standard 48mm x 38mm hole centres ensures straightforward fitment to most standard equipment frames without modification.
Key Features
- Swivel Action with Integrated Brake — Full 360-degree swivel for effortless steering, with a positive-locking brake that holds the castor firmly in place when engaged.
- Grey Rubber Tread on Polypropylene Core — Rubber compound provides quiet, smooth rolling and protects hard floor surfaces from scuffing and marking.
- Zinc-Plated Pressed Steel Top Plate — Corrosion-resistant finish suitable for indoor environments; four-hole configuration for secure, stable mounting.
- 60kg Load Capacity Per Castor — Rated for light-duty applications; a set of four supports a combined maximum of 180kg under standard conditions.
- Compact 72mm Total Height — Low-profile design integrates cleanly into furniture bases and equipment frames with minimal ground clearance requirements.
- Plain Bearing — Simple, maintenance-free bearing construction suited to light loads and moderate-frequency use.

Frequently Asked Questions
What surfaces are these castors suitable for?
The grey rubber tread is designed for use on hard, smooth floor surfaces including ceramic tile, vinyl, laminate, polished concrete, and hardwood. The rubber compound rolls quietly and does not leave marks or scuffs, making it a practical choice for retail, office, and hospitality environments where floor appearance matters.
How does the brake work, and does it lock the swivel as well?
The brake is a foot-operated, wheel-contact mechanism that presses against the rubber tread to prevent the wheel from rotating. This holds the castor — and therefore the equipment — firmly in position. Please note that this brake locks wheel rotation only; it does not lock the swivel head. If full swivel-and-wheel locking is required, a total-lock castor would be the appropriate choice.
What is the maximum load these castors can support?
Each individual castor is rated to a maximum of 60kg. When fitting a set of four castors, the combined maximum load capacity is 180kg under standard, evenly distributed conditions. For safety, it is recommended to work within 75–80% of the maximum rated load in dynamic or frequently moved applications.
What fixings are required to fit the top plate?
The four-hole top plate accepts M6 bolts (6mm diameter fixing holes) with hole centres of 48mm x 38mm across a 60mm x 60mm plate footprint. Standard M6 bolts, washers, and nuts are required for installation and are not included. Always ensure the mounting surface is flat and structurally sound to achieve the full rated load capacity.
