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 130 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 Swivel Castors with Black Rubber on Polypropylene Wheel — 80mm to 150mm
Top Plate Fixing | Ball Journal Bearing | Four Sizes Available | UK Stock
These pressed steel swivel castors are engineered for reliable, smooth-rolling mobility across a wide range of commercial, industrial, and domestic applications. Fitted with a black rubber tread bonded to a polypropylene centre wheel, they deliver quiet, floor-friendly movement with excellent grip on hard and semi-hard surfaces. The swivel head — constructed from pressed steel with a white zinc-plated finish — incorporates a double ball bearing race and a plastic dust guard for long-term performance. Mounting is via a standard four-hole top plate, making installation straightforward on trolleys, workbenches, storage units, display stands, and light industrial equipment. Available in four wheel diameters from 80mm to 150mm, with individual load ratings from 60 kg to 130 kg per castor.

* Load ratings are per individual castor. To calculate the required load rating 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 and uneven weight distribution.

Frequently Asked Questions
How do I choose the right castor size for my application?
Start by calculating the total weight of the equipment plus its maximum contents, then divide by the number of castors you intend to fit — typically four. Choose a castor whose individual load rating comfortably exceeds that figure, allowing a safety margin for dynamic loads such as pushing, pulling, and uneven surfaces. As a general guide: the 80mm castor suits light furniture and domestic use (up to 60 kg each); the 100mm is ideal for general commercial trolleys (up to 75 kg each); the 125mm handles demanding industrial use (up to 110 kg each); and the 150mm is suited to the heaviest loads (up to 130 kg each).
Are these castors suitable for use on hard floors such as tiles, concrete, or laminate?
Yes. The black rubber tread — rated at 85 Shore A — provides a firm yet slightly cushioned contact with hard floor surfaces. This hardness level offers good load-bearing capability while reducing the risk of marking or scuffing smooth floors such as tiles, sealed concrete, vinyl, and laminate. For very delicate or polished floors, we recommend testing on a small area first, as rubber compounds can occasionally leave marks under sustained static load.
What does the top plate fixing mean, and how do I fit these castors?
Top plate fixing means the castor is mounted using a flat steel plate bolted directly to the underside of the equipment frame — as opposed to a stem or bolt-hole fitting. Each castor features a 100 mm x 85 mm plate with four fixing holes of 10 mm diameter, arranged on hole centres of 80 mm (length) x 60 mm (width). To fit, simply align the plate with your equipment's pre-drilled mounting holes and secure with M10 bolts, washers, and nuts. This is the most common and secure mounting method for trolleys, workbenches, and storage units.
What is the difference between a swivel castor and a fixed castor, and do I need both?
A swivel castor rotates 360 degrees around its vertical axis, allowing the equipment to be steered and manoeuvred in any direction. A fixed castor only rolls in a straight line. For most trolleys and mobile equipment, a common configuration is two fixed castors at the rear (for straight-line stability) and two swivel castors at the front (for steering). However, four swivel castors can be used where maximum manoeuvrability in tight spaces is the priority. These castors are swivel type, making them suitable for either a full-swivel setup or a mixed configuration alongside fixed castors.
* Load ratings stated are per individual castor under static conditions. Always apply a suitable safety margin for dynamic or uneven loading. Ensure the mounting surface is structurally sound and that fixing bolts are tightened to the appropriate torque for your application.
