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 — Blue Rubber on Polypropylene Wheel, 120kg Max Load
A heavy-duty fixed castor engineered for stable, directional movement across industrial, commercial, and workshop environments. Fitted with a 100mm blue rubber-on-polypropylene wheel and a zinc-plated pressed steel top plate, this castor delivers a rated load capacity of 120kg per unit — making it the dependable choice for trolleys, shelving units, workbenches, display stands, and warehouse equipment where controlled, straight-line mobility is essential.
- Fixed (non-swivel) design — provides straight-line directional stability, ideal for guided trolleys and racking systems
- 120kg load capacity per castor — supports up to 360kg across a standard 3-castor working load configuration
- 100mm blue rubber tread on polypropylene core — absorbs vibration, protects floor surfaces, and reduces operational noise
- Pressed steel top plate with zinc plating — corrosion-resistant finish suited to damp or demanding environments
- Ball journal bearing — ensures smooth, low-effort rolling even under sustained load
- 4-bolt-hole top plate — straightforward bolt-on installation to a wide range of equipment frames

Typical Applications
This fixed castor is well suited to any application where directional control and load stability are priorities:
- Industrial trolleys and platform trucks — fixed castors at the rear maintain straight-line tracking
- Warehouse shelving and racking units — stable base movement without unwanted rotation
- Workshop benches and tool cabinets — repositionable yet directionally controlled
- Retail display stands and gondola units — floor-friendly rubber tread protects hard and tiled surfaces
- Medical and catering equipment — smooth, quiet rolling with vibration dampening
Frequently Asked Questions
What is the difference between a fixed castor and a swivel castor?
A fixed castor has a rigid bracket that allows the wheel to roll in one direction only — forward and backward. A swivel castor rotates 360° to allow multi-directional movement. Fixed castors are typically used in combination with swivel castors: fixed at the rear for straight-line guidance, swivel at the front for steering. This castor is a fixed type.
How many castors do I need, and what is the total load capacity?
Most equipment uses four castors, but the industry-standard working load calculation is based on three castors bearing the load (to account for uneven surfaces). With a 120kg rating per castor, the recommended maximum working load for a set of four is 360kg. Always ensure your total equipment weight — including contents — does not exceed this figure.
Is the blue rubber tread suitable for use on hard floors such as tiles, concrete, or wood?
Yes. The blue rubber tread at 75 Shore A hardness is designed to provide grip and floor protection across a range of hard surfaces including concrete, ceramic tile, vinyl, and sealed timber. The rubber compound absorbs minor surface irregularities and reduces rolling noise, making it appropriate for both industrial and light commercial settings.
How do I install this castor — what fixings are required?
This castor mounts via a 4-bolt-hole top plate. The plate measures 100mm x 85mm with hole centres of 60mm and 80mm, and a hole diameter of 10mm. Standard M10 bolts, washers, and nuts (not supplied) are required. Ensure the mounting surface is flat, structurally sound, and capable of bearing the intended load before installation.
