These light duty braked bolt hole swivel castors are engineered for equipment that demands controlled, reliable mobility on smooth, dry, level surfaces. Fitted with a black polypropylene wheel and secured via a single M10 bolt hole, each castor delivers straightforward installation and a firm, stable connection to the host equipment. The integrated brake mechanism locks the wheel in position when stationary, preventing unwanted movement and improving operational safety.

Available in three wheel diameters — 50mm, 75mm, and 100mm — these swivel castors are suited to a broad range of light duty commercial and industrial applications including shop fitting, retail display, office furniture, exhibition stands, and light warehouse use. Select the size that matches your load requirements and floor clearance needs. Before ordering, always confirm that the individual castor load rating meets or exceeds one quarter of the total loaded equipment weight, with an appropriate safety margin applied.

About This Option

The 50mm bolt hole braked swivel castor is the most compact option in this range, making it well suited to lower-profile equipment and applications where minimal floor clearance is required. With a total height of just 72mm and a swivel radius of 80mm, it manoeuvres easily in confined spaces. The plain bearing construction keeps rolling resistance low on smooth surfaces, while the integrated brake provides reliable hold when the equipment is stationary.

Typical Applications
  • Shop fitting — moving display units, shelving bays, and retail fixtures
  • Exhibition and event stands — repositioning lightweight display structures
  • Light furniture — office chairs, small trolleys, and mobile storage units
  • Hospitality — bar stools, service trolleys, and front-of-house furniture
  • Domestic and light commercial appliance movement on smooth flooring

About This Option

The 75mm option strikes the ideal balance between compactness and load-bearing capability, offering a 75kg per castor rating and a total height of 100mm. The wider swivel radius of 92mm gives this size excellent directional control across larger floor areas, making it a popular choice for retail, warehousing, and workshop environments. The braked mechanism engages cleanly to hold equipment firmly in place during loading, unloading, or stationary use.

Typical Applications
  • Retail and shop fitting — gondola shelving, display stands, and mobile counters
  • Light warehousing — picking trolleys, stock cages, and packing benches
  • Workshop environments — mobile workstations and tool storage units
  • Office furniture — mobile pedestals, printer stands, and reconfigurable desks
  • Catering and hospitality — service trolleys and mobile preparation tables

About This Option

The 100mm castor is the largest and highest-capacity option in this range, rated at 85kg per castor and offering a total height of 122mm. The increased wheel diameter reduces rolling resistance over longer distances and provides greater ground clearance, making it the preferred choice for heavier light duty loads and equipment that is moved regularly across open floor areas. The 97mm swivel radius ensures responsive directional control even when the equipment is fully loaded.

Typical Applications
  • Light warehousing and distribution — picking trolleys, roll cages, and mobile racking
  • Manufacturing support — component trolleys and assembly line mobile units
  • Facilities management — janitorial trolleys, equipment carts, and mobile storage
  • Retail back-of-house — stock movement, goods-in trolleys, and mobile shelving
  • Domestic and light commercial use — appliance movement and furniture repositioning
Frequently Asked Questions
How do I calculate the correct load capacity for my equipment?
Divide the total loaded weight of your equipment by the number of castors you intend to fit. The result must not exceed the rated load capacity of each individual castor. It is strongly recommended to apply a safety margin of at least 25–30% above the calculated per-castor load to account for uneven weight distribution, dynamic loads during movement, and floor surface variations. For example, if your equipment weighs 200kg and you are fitting 4 castors, each castor must be rated for at least 50kg — and ideally 65kg or above when a safety margin is applied.
What does the bolt hole fixing mean, and how is it installed?
A bolt hole castor is fixed to the equipment using a single bolt passed through a pre-drilled hole in the mounting surface. These castors use an M10 bolt hole (10mm diameter). The bolt is inserted through the equipment leg or base plate and secured with a nut and washer on the underside of the castor housing. This fixing method provides a strong, rigid connection and is commonly used on tubular steel furniture legs, equipment frames, and fabricated bases where a top plate fitting is not suitable.
Are these castors suitable for outdoor use or wet environments?
These castors are designed for use on smooth, dry, level indoor floor surfaces. The polypropylene wheel performs well in clean, dry conditions. They are not recommended for outdoor use, wet or damp environments, or surfaces with significant debris, as these conditions can affect rolling performance, braking effectiveness, and the longevity of the plain bearing. For outdoor or wet-area applications, a castor with a more robust bearing type and a suitable tread material should be selected.
Which size should I choose — 50mm, 75mm, or 100mm?
The right size depends on three factors: load requirement, floor clearance, and the distance the equipment will be moved. The 50mm castor (65kg rated, 72mm total height) suits compact, lower-profile equipment moved over short distances. The 75mm castor (75kg rated, 100mm total height) is the most versatile option and works well across retail, office, and light warehouse settings. The 100mm castor (85kg rated, 122mm total height) is best for heavier loads or equipment moved regularly over longer distances, as the larger wheel rolls more easily and reduces effort. If in doubt, select the next size up to ensure adequate capacity and ease of movement.
All castors are dispatched from UK stock. Load capacities stated are per individual castor. Always ensure the combined rated capacity of your chosen castors exceeds the maximum loaded weight of your equipment, with an appropriate safety margin applied.
