75mm Pressed Steel Fixed Castor Wheel - White Nylon Wheel & 4-Bolt-Hole - 75kg Load Capacity

75mm Pressed Steel Fixed Castor Wheel ? White Nylon Wheel, 4-Bolt Top Plate, 75kg Load Capacity What it is: A 75mm diameter fixed castor constructed with a pressed steel top plate and a white nylon wheel, designed for straight-line directional movement without swivel. What it?s used for: Engineered for trolleys, workshop benches, shelving units, retail display stands, and light industrial equipment where a fixed rolling direction is required. The nylon wheel rolls quietly and cleanly across hard floors, tiles, and smooth concrete, making it equally at home in commercial, retail, and light warehouse environments. Fixed Castor 75kg Load Rated White Nylon Wheel Zinc Plated Plate Plain Bearing Key Features Wheel Diameter 75mm ? an efficient mid-range diameter that balances rolling ease with compact overall height. Load Capacity 75kg per castor (225kg maximum for a set of four, using three load-bearing castors as standard practice). Wheel Material White nylon ? hard-wearing, low-noise, and resistant to oils, greases, and general workshop fluids. Tread Width 22mm ? provides a stable contact footprint without excessive rolling resistance. Top Plate Construction Pressed steel with a zinc-plated finish for corrosion resistance in damp or humid environments. Bearing Type Plain (bore) bearing ? maintenance-free and well-suited to moderate-duty, consistent-load applications. Castor Type Fixed (non-swivel) ? ideal where straight-line movement and directional stability are priorities. Mounting 4-bolt top plate ? secure, rigid attachment to equipment frames, bases, and platforms.

Always consult a qualified engineer for safety-critical applications. Typical Applications Warehouse & Storage Trolleys, picking carts, and mobile shelving units where straight-line tracking is essential for aisle navigation. Workshop & Industrial Tool carts, workbenches, and equipment stands requiring a stable, fixed-direction rolling base. Retail & Display Display plinths, gondola units, and promotional stands that need repositioning without swivel drift. Commercial Furniture Office and hospitality furniture bases, catering trolleys, and AV equipment stands on hard floor surfaces. Frequently Asked Questions What is the difference between a fixed castor and a swivel castor? A fixed castor rolls in one direction only, providing straight-line movement and greater directional stability. A swivel castor rotates 360? to allow multi-directional movement. Fixed castors are typically used at the rear of a trolley or cart, paired with swivel castors at the front, to give both manoeuvrability and control. Is this castor suitable for use on hard floors such as tiles or concrete? Yes. The white nylon wheel is specifically well-suited to hard, smooth floor surfaces including ceramic tiles, sealed concrete, vinyl, and hardwood. It rolls quietly and leaves no marks, making it a practical choice for both industrial and commercial interiors. How do I calculate the total load capacity I need for my application? As a general guide, divide the total weight of the loaded equipment by three (not four), as it is standard practice to assume only three of the four castors bear the full load at any one time due to floor irregularities. For this castor, the maximum recommended load for a set of four is 225kg. Always apply an appropriate safety margin and seek professional advice for critical load-bearing applications. What fixings do I need to mount this castor? This castor uses a 4-bolt top plate with a plate size of 67mm x 60mm and hole centres of 48mm x 38mm. Each hole accepts an M6 bolt (6mm diameter). Standard M6 bolts, washers, and nuts are widely available and are not supplied with the castor. Ensure the mounting surface is flat, rigid, and of sufficient thickness to support the intended load.
