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
This 50mm swivel castor features a grey rubber tyre bonded to a polypropylene wheel centre, mounted on a zinc plated pressed steel top plate with four fixing holes. Rated to 60 kg per castor, it is designed for light-duty mobility applications including shop fitting, retail display units, office furniture, trolleys, and workshop equipment. The swivel action delivers smooth, responsive directional control across hard and semi-hard floor surfaces, while the rubber tyre provides a degree of floor protection and quiet running.

Frequently Asked Questions
What is the maximum weight this castor can support?
Each castor is rated to 60 kg. When fitting a set of four castors, the combined maximum load is calculated on a three-point loading basis, giving a practical set capacity of 180 kg. Always ensure the load is evenly distributed across all castors.
Will this castor scratch or mark my floor?
The grey rubber tyre is designed to be non-marking on most hard floor surfaces including wood, laminate, vinyl, and tile. It also provides a degree of cushioning and quiet running compared to hard plastic wheels.
How do I fit this castor to my equipment?
The castor uses a 4-hole top plate measuring 60 mm × 60 mm, with hole centres at 48 mm / 38 mm and a hole diameter of 6 mm. It can be bolted directly to a flat surface using M5 or M6 bolts (not supplied). The dual-pitch hole pattern provides compatibility with a wide range of standard fittings.
Is a braked version of this castor available?
This listing is for the swivel castor without a brake. A braked swivel version with the same wheel specification and plate dimensions is available separately in our castor range — ideal for applications where the equipment needs to be locked in position.
