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
This 125mm fixed castor is a robust, non-swivel wheel unit engineered for straight-line movement on industrial trolleys, workshop carts, shelving units, and heavy-duty mobile equipment. Constructed with a grey rubber tyre bonded to a pressed steel centre, it delivers reliable load-bearing performance up to 110kg per wheel while protecting hard floor surfaces from marking and impact damage. Suited to warehousing, manufacturing, retail, and hospitality environments where directional stability and floor care are equally important.

- ? Ball journal bearing — smooth, low-effort rolling under load
- ? Zinc-plated pressed steel top plate — corrosion-resistant finish for long service life
- ? 110kg load capacity per castor — suitable for medium to heavy-duty applications
- ? Floor-safe rubber tyre — non-marking on hard floor surfaces
Typical Applications
This fixed castor is widely specified across a broad range of commercial and industrial settings where controlled, straight-line movement is required:
- * Warehouse picking trolleys and goods transport carts
- * Workshop benches and tool storage units
- * Retail display fixtures and shelving units
- * Hospitality service trolleys and catering equipment
- * Healthcare and facilities management mobile equipment
Installation Note
This castor is supplied as a single unit. For a standard four-castor trolley or platform, a set of four is recommended — typically two fixed castors at the rear and two swivel castors at the front for optimal manoeuvrability. Fixing bolts are not included; M8 bolts are suitable for the 9mm fixing holes. Always verify the combined load capacity of all castors against the total loaded weight of the equipment before installation.
Frequently Asked Questions
What is the difference between a fixed castor and a swivel castor?
A fixed castor rolls in one direction only — it cannot rotate on a vertical axis. This makes it ideal for the rear wheels of trolleys and carts where straight-line stability is needed. A swivel castor can rotate 360 degrees, allowing the equipment to be steered and turned. Most mobile equipment uses a combination of both types for the best balance of control and manoeuvrability.
Will this castor mark or damage hard floor surfaces?
The grey rubber tyre is a non-marking compound, making it suitable for use on polished concrete, vinyl, ceramic tiles, hardwood, and similar hard floor surfaces. It will not leave black scuff marks or tyre residue under normal operating conditions.
How many castors do I need, and what total load can they support?
Each castor is rated to 110kg. A set of four castors provides a combined theoretical capacity of 440kg. In practice, it is recommended to apply a safety factor and not exceed 75–80% of the combined rated capacity to account for uneven load distribution and dynamic forces during movement. Always calculate based on the fully loaded weight of the equipment.
What fixings are required to fit this castor?
The top plate has four 9mm fixing holes on 80mm x 60mm hole centres. M8 bolts with appropriate washers and nuts are suitable for most installations. The bolts are not included with the castor. Ensure the mounting surface is flat, structurally sound, and capable of bearing the intended load before fitting.
