Description
Pressed Steel Fixed Castors — Grey Rubber on Black Polypropylene Wheel
A robust, directionally fixed castor designed for controlled, straight-line movement of furniture, equipment trolleys, and industrial platforms. Constructed with a pressed steel top plate and a dual-compound wheel combining a grey rubber tread over a black polypropylene core, these castors deliver quiet, floor-friendly rolling performance across a wide range of indoor surfaces. Available in three wheel diameters — 50mm, 75mm, and 100mm — each size is load-rated and ready to dispatch from UK stock.

Construction & Materials
Each castor is built around a pressed steel top plate — a cold-formed steel bracket that provides a rigid, flat mounting surface for bolt-down installation. The plate features four pre-drilled bolt holes arranged in a standard pattern, allowing straightforward fitting to most furniture and equipment frames without specialist tooling.
The wheel uses a dual-compound construction: a black polypropylene (PP) core provides structural rigidity and impact resistance, while an outer grey rubber tread delivers grip, noise reduction, and protection for hard floor surfaces including timber, vinyl, tile, and sealed concrete. The rubber compound is non-marking under normal indoor conditions.
The fixed (non-swivel) yoke design locks the wheel in a single rolling direction, making these castors ideal for straight-line guided movement where directional stability is a priority — typically used in combination with swivel castors on the same platform.
Fitting & Installation Guide
These castors are designed for bolt-on top plate installation. The four-hole plate pattern is a widely adopted standard; however, always verify the hole spacing against your equipment frame before ordering. Use appropriately rated bolts and locking nuts to secure the plate firmly. For mixed configurations, pair fixed castors at the rear of a platform with swivel castors at the front to allow controlled directional steering.
* Always ensure the combined load rating of all fitted castors exceeds the maximum loaded weight of the equipment. Apply a minimum 25% safety margin above the expected working load.
