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
100mm Pressed Steel Fixed Castor Wheel — Grey Rubber on Pressed Steel — 75kg Load Capacity
A robust, top-plate fixed castor engineered for demanding industrial, commercial, and institutional environments where directional stability and floor protection are equally critical.
This 100mm fixed castor features a grey rubber tread bonded to a pressed steel centre wheel, mounted on a zinc-plated pressed steel top plate with a ball journal bearing. Designed for straight-line movement on trolleys, carts, shelving units, and mobile workstations, it delivers a reliable 75kg load capacity per castor — supporting up to 220kg across a four-castor configuration. The rubber tread absorbs vibration, reduces rolling noise, and protects sensitive floor surfaces, making it a practical choice for warehouses, workshops, retail back-of-house, healthcare facilities, and hospitality settings.
- Load Capacity (per castor) 75 kg — dependable support for heavy trolleys and mobile equipment
- Max Load (4-castor set) 220 kg — suitable for fully loaded carts and platform trucks
- Wheel Material Grey rubber tread on pressed steel centre — balances grip, resilience, and floor protection
- Tread Hardness 85 Shore A — firm enough for heavy loads, compliant enough to absorb surface irregularities
- Bearing Type Ball journal — smooth, low-effort rolling under sustained load
- Castor Type Fixed (non-swivel) top-plate — ideal for straight-line directional control
- Finish Zinc-plated pressed steel plate — corrosion-resistant for indoor and light-duty environments
Technical Specifications
Typical Applications
Warehousing & Logistics
Ideal for platform trolleys, picking carts, and mobile racking systems that travel fixed routes across warehouse floors.
Workshops & Manufacturing
Suited to tool trolleys, parts bins, and mobile workbenches where straight-line stability under load is essential.
Healthcare & Institutional
The rubber tread minimises noise and floor marking, making it appropriate for hospital trolleys and catering equipment.
Retail & Hospitality
Suitable for back-of-house trolleys, display units, and service carts where a clean, quiet roll is required.
Frequently Asked Questions
What is the difference between a fixed castor and a swivel castor?
A fixed castor is mounted in a set direction and does not rotate on a vertical axis, so it only moves in a straight line. A swivel castor can rotate 360°, allowing multi-directional movement. Fixed castors are typically used in combination with swivel castors — for example, two fixed at the rear and two swivel at the front — to provide both directional control and manoeuvrability.
How many castors do I need, and what is the total load they can support?
For most trolleys and carts, four castors are used. This 75kg-per-castor model supports a maximum combined load of 220 kg across a four-castor set. When calculating your requirements, always account for the weight of the equipment itself in addition to the intended load, and apply a safety margin of at least 20–25%.
Is the rubber wheel suitable for use on hard floors such as tiles, concrete, or vinyl?
Yes. The grey rubber tread at 85 Shore A hardness is well suited to smooth hard floors including concrete, ceramic tile, vinyl, and sealed timber. The rubber compound provides adequate grip and absorbs minor surface vibrations without marking or scuffing the floor surface under normal operating conditions.
How do I fit this castor using the top plate?
The top plate measures 100 mm x 85 mm with four bolt holes of 10 mm diameter. The hole centres are spaced at 60 mm and 80 mm widths, accommodating standard bolt patterns. Secure the plate to your equipment using M10 bolts (not supplied), ensuring the mounting surface is flat and structurally sound to achieve the rated load capacity.
