50mm Light Duty Swivel Castors With Grey Rubber Wheel — Bolt Hole M8 & M10
50mm Wheel Diameter | Plain Bearing | M8 or M10 Bolt Hole Fixing | Swivel Action | UK Stock — Ready to Dispatch
These 50mm light duty swivel castors are compact, reliable bolt hole castors fitted with a grey rubber-treaded polypropylene wheel. Designed for straightforward single-bolt fixing directly through a pre-drilled hole in your equipment frame, they are available in two bolt hole sizes — M8 and M10 — to suit a wide range of standard fittings. The swivel head allows full 360-degree rotation, making them ideal for any application where frequent directional changes and easy repositioning are required.
With a 50kg load capacity per castor and a combined maximum of 150kg across a set of four, these castors are well suited to light duty mobile equipment in retail, commercial, and light industrial environments. The grey rubber tread provides quiet, floor-friendly rolling on smooth and semi-smooth surfaces, reducing noise and protecting floor finishes during everyday use.

The M8 bolt hole variant is the most widely compatible option for light duty mobile equipment with standard 8mm pre-drilled fixing points. The single bolt hole design allows for a clean, secure installation without the need for a top plate, making it particularly suited to slim-profile frames, shelving units, and display fixtures where space around the fixing point is limited. The 20mm tread width provides a slightly broader contact footprint, contributing to stable, smooth rolling across a variety of floor surfaces.
- 50mm wheel diameter — compact profile suitable for low-clearance equipment
- 70mm total castor height — consistent ground clearance for standard light duty frames
- 20mm tread width — broader contact area for stable rolling
- 52mm swivel radius — responsive turning in confined spaces
- M8 (8mm) bolt hole — direct fixing through pre-drilled holes, no plate required
- 50kg load capacity per castor — reliable support for light duty loads
- Grey rubber tread on polypropylene core — quiet, floor-friendly operation
- Plain bearing — low-maintenance, smooth rotation for everyday use
- Full 360-degree swivel — unrestricted directional movement
- Retail Display Fixtures: Ideal for repositioning gondola shelving, display stands, and point-of-sale units in retail environments where M8 fixings are standard.
- Shop Fitting & Fit-Out: Suited to mobile display cases, clothing rails, and modular shop furniture that require frequent repositioning.
- Light Duty Trolleys & Carts: Appropriate for picking trolleys, mail room carts, and general-purpose utility trolleys in offices and light commercial settings.
- Hospitality & Catering Equipment: Suitable for mobile service trolleys, bar carts, and catering equipment in hotels, restaurants, and event venues.
- Workshop & Storage Units: Useful for mobile tool cabinets, parts bins, and storage units in light workshop environments.
- Medical & Healthcare Furniture: Compatible with lightweight mobile medical furniture and equipment trolleys where quiet, smooth rolling is required.

The M10 bolt hole variant is designed for equipment with larger 10mm fixing points, which are commonly found on heavier-gauge steel frames, industrial trolleys, and commercial furniture where a more robust bolt fixing is specified. Sharing the same 50mm wheel diameter, 70mm total height, and 50kg load capacity as the M8 option, this variant delivers identical performance characteristics with the added security of a larger diameter bolt fixing. The 17mm tread width gives a slightly narrower contact profile, making it well suited to harder, smoother floor surfaces.
- 50mm wheel diameter — consistent compact profile matching the M8 variant
- 70mm total castor height — uniform ground clearance across both variants
- 17mm tread width — narrower profile suited to smooth, hard floor surfaces
- 52mm swivel radius — identical manoeuvrability to the M8 option
- M10 (10mm) bolt hole — suits heavier-gauge frames with larger pre-drilled fixings
- 50kg load capacity per castor — consistent light duty load rating
- Grey rubber tread on polypropylene core — quiet, floor-protective rolling
- Plain bearing — simple, maintenance-free rotation
- Full 360-degree swivel — unrestricted directional movement
- Commercial & Industrial Trolleys: Suited to heavier-gauge trolleys and carts with M10 pre-drilled fixing points in warehousing and light industrial environments.
- Retail & Warehouse Fixtures: Appropriate for mobile racking units, stock room trolleys, and warehouse picking carts where M10 fixings are specified.
- Hospitality Equipment: Compatible with commercial catering trolleys, linen carts, and housekeeping equipment in hotels and large hospitality venues.
- Office & Facilities Management: Useful for mobile filing units, AV trolleys, and facilities management equipment with M10 bolt hole frames.
- Display & Exhibition Equipment: Suitable for exhibition stands, mobile display boards, and event furniture requiring a secure M10 bolt fixing.
