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

Enter the weight of the item plus its heaviest load. This castor is rated 140 kg each.

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

Pressed Steel Fixed Castors With Blue Rubber on Black Polypropylene Wheel — 100mm & 125mm

Top Plate Fitting  |  Ball Journal Bearing  |  UK Stock


These pressed steel fixed castors are engineered for reliable, straight-line movement across a wide range of commercial and light industrial environments. Each castor features a blue rubber tread bonded to a black polypropylene wheel core, mounted within a robust pressed steel bracket and secured via a four-hole top plate. The fixed (non-swivel) design ensures directional stability, making these castors the preferred choice wherever controlled, linear travel is required — from warehouse trolleys and workshop benches to distribution racking and institutional equipment.

Available in two wheel diameters — 100mm and 125mm — each size is independently rated for load capacity and optimised for its intended application. Select the size that best matches your equipment's weight requirements and floor clearance needs using the comparison table and detailed specification cards below.

* Load ratings are per individual castor. To calculate the required load capacity per castor, divide the total equipment weight (including contents) by the number of castors fitted — typically four. Always apply an appropriate safety margin to account for dynamic loads, uneven weight distribution, and floor surface conditions.

Detailed Specifications and Applications by Size

100mm Pressed Steel Fixed Castor — Blue Rubber on Black Polypropylene Wheel

120kg Load Capacity per Castor  |  360kg Maximum for a Set of Four
Product Overview

The 100mm fixed castor delivers dependable, straight-line mobility for everyday commercial and light industrial use. Its blue rubber tread provides a smooth, quiet roll while protecting floor surfaces from marking and abrasion. The pressed steel bracket offers a rigid, low-profile housing, and the four-hole top plate allows straightforward bolt-on installation to compatible equipment frames. With a 120kg individual load rating, this size is well suited to trolleys, benches, and mobile storage units operating in moderate-duty environments.

Applications

The 100mm option is the go-to choice for moderate-duty applications where floor protection and quiet operation are priorities. Its compact height of 127mm makes it ideal for low-clearance equipment, and the 32mm tread width distributes load effectively across smooth and semi-smooth surfaces.

  • Warehouse picking trolleys and order fulfilment carts requiring directional stability
  • Workshop benches and tool storage units moved periodically across concrete or tiled floors
  • Retail display units and mobile shelving in shop-floor environments
  • Light assembly line equipment and production support trolleys
  • Office and hospitality furniture requiring occasional repositioning without floor damage
  • Mail room and print room trolleys in commercial office buildings

125mm Pressed Steel Fixed Castor — Blue Rubber on Black Polypropylene Wheel

140kg Load Capacity per Castor  |  420kg Maximum for a Set of Four
Product Overview

The 125mm fixed castor steps up in both wheel diameter and load capacity, making it the preferred choice for heavier equipment and more demanding operational environments. The larger 125mm wheel rolls more easily over minor floor irregularities and transitions, reducing rolling resistance and operator effort. At 157mm total height, it provides additional ground clearance suitable for heavier trolleys, institutional carts, and industrial support equipment. The 37.5mm tread width and 75 Shore A rubber compound maintain excellent floor protection while supporting loads up to 140kg per castor.

Applications

The 125mm option is engineered for environments where higher load ratings and improved floor-obstacle clearance are essential. The wider tread and larger diameter combine to deliver a noticeably smoother push across uneven or textured surfaces, reducing fatigue in high-frequency handling operations.

  • Distribution centre goods trolleys and heavy-duty picking carts handling dense stock
  • Industrial workshop equipment including welding benches and heavy tool storage
  • Healthcare and institutional laundry trolleys, linen carts, and catering equipment
  • Hospitality service trolleys in hotels, conference centres, and large catering operations
  • Logistics and freight handling equipment in loading bays and sorting facilities
  • Education and laboratory mobile benching requiring stable, directional movement
Frequently Asked Questions
What is the difference between the 100mm and 125mm options, and how do I choose the right size?
The primary differences are wheel diameter, total castor height, tread width, and load capacity. The 100mm castor stands 127mm tall and supports up to 120kg per unit (360kg for a set of four), making it well suited to lighter trolleys, benches, and display units. The 125mm castor stands 157mm tall and supports up to 140kg per unit (420kg for a set of four), offering greater ground clearance and improved rolling performance over minor floor irregularities. As a general rule, choose the 100mm for moderate-duty, low-clearance applications and the 125mm where heavier loads or slightly uneven floors are involved. Always divide your total equipment weight (including contents) by four and apply a safety margin before selecting your load rating.
Will these castors mark or damage my floors?
These castors are fitted with a blue rubber tread rated at 75 Shore A — a hardness level that balances load-bearing performance with floor protection. The rubber compound is formulated to be non-marking on smooth and semi-smooth surfaces including sealed concrete, vinyl, ceramic tile, and hardwood. For particularly sensitive or polished floors, we recommend confirming suitability with a short rolling test before full deployment. The wider tread on the 125mm option (37.5mm versus 32mm on the 100mm) distributes load over a greater contact area, further reducing the risk of surface indentation under heavy loads.
How are these castors fitted, and what fixings are required?
Both sizes use a four-hole top plate measuring 100mm x 85mm, with hole centres of 80mm (length) x 60mm (width) and a plate hole diameter of 10mm. This is a standard top plate configuration compatible with a wide range of commercial and industrial equipment frames. Fitting requires four M8 or M10 bolts (depending on your equipment's thread specification), washers, and locking nuts — these are not supplied and should be sourced separately to match your specific application. Ensure the mounting surface is flat, clean, and structurally sound before installation.
Are these fixed castors suitable for use alongside swivel castors on the same equipment?
Yes — fixed castors are commonly paired with swivel castors in a four-castor configuration to achieve both directional stability and manoeuvrability. The standard arrangement is to fit two fixed castors at the rear of the equipment (to maintain a straight travel line) and two swivel castors at the front (to allow steering and turning). Both the 100mm and 125mm fixed castors in this listing share the same top plate dimensions (100mm x 85mm) and hole pattern as many compatible swivel castor options, making mixed configurations straightforward. Always ensure all castors in a set share the same wheel diameter to maintain a level, stable platform.
* Load ratings stated are per individual castor under controlled static conditions. For dynamic applications — including equipment that is pushed, pulled, or subject to impact loading — apply a minimum safety factor of 1.5 to 2 times the calculated per-castor load. Consult a qualified engineer if your application involves continuous heavy-duty use, ramp transitions, or uneven floor surfaces.
