Top Plate Mounting Details

This fixed castor wheel is specifically designed for environments requiring controlled directional movement and floor protection. The thermoplastic rubber wheel material provides excellent grip whilst remaining gentle on delicate flooring surfaces including vinyl, laminate, tile, and polished concrete.

Perfect for retail display units, shop fixtures, mobile shelving systems, point-of-sale stands, exhibition equipment, light warehouse trolleys, service carts, and any application where straight-line stability is essential. The zinc plated finish offers reliable corrosion resistance for indoor commercial settings.

What is the difference between a fixed castor and a swivel castor?

A fixed castor only moves in a straight line, providing directional stability and preventing unwanted rotation. Swivel castors rotate 360 degrees, offering greater manoeuvrability. Fixed castors are typically used in combination with swivel castors, or alone when straight-line movement is required.

Will this castor mark or damage my floors?

No, the grey thermoplastic rubber wheel is specifically designed to be non-marking and floor-friendly. It is suitable for use on vinyl, laminate, tile, polished concrete, and other smooth commercial flooring surfaces without leaving scuff marks or causing damage.

How much weight can this castor support?

This castor has a load capacity of 80kg. When using multiple castors on a single unit, calculate the total weight (equipment plus contents) and ensure it is distributed evenly across all castors. For example, four castors would support up to 320kg total when weight is properly distributed.

What are the mounting hole dimensions on the top plate?

The top plate measures 95mm x 70mm with a standard 4-hole fixing pattern. This is a common configuration compatible with most retail fixtures and mobile equipment. Ensure your mounting surface has adequate thickness and strength to support the fixing bolts and anticipated load.

Is this castor suitable for outdoor use?

This castor is designed primarily for indoor commercial environments. Whilst the zinc plated finish provides some corrosion resistance, prolonged exposure to moisture, rain, or harsh outdoor conditions may reduce its lifespan. For permanent outdoor applications, consider castors with enhanced weatherproofing.

What does the 88 Shore A hardness rating mean?

Shore A hardness measures the firmness of the rubber wheel material. An 88 Shore A rating indicates a relatively firm rubber that provides good load-bearing capability whilst still offering some cushioning and floor protection. This hardness level balances durability with noise reduction and smooth rolling performance.

Can I use these castors on carpet?

Whilst these castors will function on low-pile commercial carpet, they are optimised for hard, smooth flooring surfaces. On thick or high-pile carpet, rolling resistance will increase significantly and may affect manoeuvrability. For regular carpet use, consider larger diameter wheels or castors specifically designed for soft surfaces.

What is a plain bearing and how does it compare to ball bearings?

A plain bearing uses a simple sleeve design where the axle rotates within a bushing. Plain bearings are cost-effective, reliable, and suitable for light-to-medium duty applications with moderate rolling frequency. Ball bearings offer smoother rolling and greater load capacity but at a higher cost. For retail displays and occasional movement, plain bearings provide excellent value and performance.
