Description
Zinc Plated Fixed Castors with Grey Thermoplastic Rubber Wheel
These zinc plated fixed castors are fitted with a grey thermoplastic rubber (TPR) wheel mounted on a polypropylene centre, delivering quiet, floor-friendly movement across a wide range of commercial and institutional surfaces. Available in four wheel diameters — 60mm, 80mm, 100mm, and 125mm — with load ratings from 40kg up to 100kg per castor, this range is engineered for retail displays, medical trolleys, office furniture, warehouse equipment, and light-duty industrial applications where a fixed, straight-line castor is required.
Each castor features a zinc plated top plate for corrosion resistance, a plain bearing for low-maintenance operation, and a grey TPR tread rated at 88 Shore A hardness — firm enough for durability, yet compliant enough to protect sensitive flooring. Select the size that matches your load requirement and mounting plate dimensions from the variant options above.
Available in Multiple Castor Wheel Sizes & Types
Explore this castor wheel range in different types. Available in multiple sizes with different load capacities.

This size is a popular choice for retail trolleys, catering equipment, and office storage units where moderate loads need to be moved reliably and quietly.
Key Features
- 80mm wheel diameter for improved roll over uneven surfaces
- 50kg load capacity per castor — suitable for moderate loads
- Total castor height of 107mm
- 22mm tread width for balanced stability

100mm Fixed Castor — Grey TPR Wheel — 80kg Load Capacity
The 100mm fixed castor is the mid-to-heavy option in this range, rated to 80kg per castor and built for applications where heavier loads must be moved with control and minimal floor impact. The larger 95mm x 70mm plate provides a more secure mounting footprint, and the 30mm tread width distributes weight more evenly across the floor surface. At 134mm overall height, this castor suits warehouse trolleys, industrial shelving units, and heavy retail fixtures that require dependable straight-line movement.
Key Features
- 100mm wheel diameter for smooth movement under heavier loads
- 80kg load capacity per castor
- Total castor height of 134mm
- 30mm tread width for improved load distribution
- Grey TPR wheel on polypropylene centre
- 88 Shore A tread hardness
- Larger 95mm x 70mm zinc plated top plate

Frequently Asked Questions
What is the difference between a fixed castor and a swivel castor?
A fixed castor is mounted in a rigid bracket that allows movement in one direction only — straight forward or backward. It does not rotate on a vertical axis. Fixed castors are typically used in combination with swivel castors on trolleys and carts: the fixed castors provide directional stability and straight-line tracking, while the swivel castors at the opposite end allow steering. If you need full 360-degree manoeuvrability from a single castor, a swivel castor would be the appropriate choice.
How do I choose the correct castor size for my application?
Two factors determine the correct size: load capacity and overall height. First, calculate the total weight of the loaded equipment and divide by the number of castors — the result must not exceed the per-castor load rating. Second, check the overall castor height against the clearance available on your equipment. Larger wheel diameters also roll more easily over minor floor imperfections and reduce rolling resistance under heavier loads. Use the combined specification table at the top of this page to compare all four options side by side.
Are these castors suitable for use on hard floors such as tiles, vinyl, or laminate?
Yes. The grey thermoplastic rubber tread is non-marking and floor-safe on hard surfaces including ceramic tile, vinyl, laminate, polished concrete, and hardwood. The 88 Shore A hardness rating means the tread is firm enough to roll efficiently under load without deforming, while remaining compliant enough to avoid scratching or scuffing sensitive floor finishes. These castors are not intended for outdoor use or heavily contaminated surfaces.
How are these castors mounted, and what fixings are required?
All four variants use a top plate (also known as a face plate) mounting system. The plate is bolted directly to the underside of the equipment using the pre-drilled hole pattern. The 60mm and 80mm models use a 65mm x 50mm plate with 6mm diameter holes on 50mm x 36mm centres. The 100mm and 125mm models use a larger 95mm x 70mm plate with 8mm diameter holes on dual centres of 76/70mm x 50/44.5mm, providing compatibility with a wider range of equipment frames. Standard M6 or M8 bolts and washers (not supplied) are used to secure the plate.
