This 150mm fixed castor is engineered for professional environments where stability, load capacity, and straight-line movement are critical:

• Heavy-duty industrial trolleys and transport carts
• Mobile workstations and equipment stands
• Warehouse handling equipment and pallet trucks
• Manufacturing assembly line equipment
• Retail display units and merchandising fixtures
• Hospitality service trolleys and catering equipment
• Healthcare mobile storage and medical equipment
• Workshop tool cabinets and storage systems
• Indoor environments requiring controlled directional movement under heavy loads

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

A fixed castor only moves in a straight line along its mounting axis, providing stability and directional control. A swivel castor rotates 360 degrees, allowing for greater manoeuvrability. Fixed castors are typically used on the rear of equipment for stability, while swivel castors are placed at the front for steering.

Can this castor be used on all floor types?

Yes, the polyurethane on nylon wheel is suitable for most indoor floor surfaces including concrete, tile, vinyl, laminate, and sealed wood. The 85 Shore A hardness provides floor protection while maintaining excellent load-bearing performance. However, it is designed for indoor use and may not be suitable for outdoor or rough terrain applications.

How do I determine the correct load capacity for my application?

Calculate the total weight of your equipment plus the maximum load it will carry, then divide by the number of castors. Add a safety margin of 25-30% to account for uneven weight distribution and dynamic loads. For example, if your total weight is 400kg across 4 castors, each castor should be rated for at least 125-130kg. This 180kg castor provides ample capacity for such applications.

What are the benefits of a ball journal bearing?

Ball journal bearings provide smooth, low-friction rotation with excellent load distribution. They require minimal maintenance, offer superior rolling performance compared to plain bearings, and maintain consistent operation even under heavy loads. This results in easier movement, reduced operator fatigue, and extended service life.

How do I install this top plate castor?

Position the castor mounting plate on your equipment base, ensuring proper alignment. Mark the four hole positions using the plate as a template. Drill holes appropriate for your chosen fasteners (10mm diameter holes accommodate M8 or M10 bolts). Secure the castor using bolts, washers, and lock nuts, tightening evenly to ensure the plate sits flush and level.

Why choose polyurethane wheels over rubber or plastic?

Polyurethane offers superior load capacity, abrasion resistance, and floor protection compared to standard rubber or plastic wheels. It provides low rolling resistance for easier movement, operates quietly, resists oils and many chemicals, and maintains performance across a wide temperature range. The nylon core adds structural strength while keeping the wheel lightweight.

What does 85 Shore A hardness mean?

Shore A is a measurement scale for material hardness. 85 Shore A indicates a relatively hard polyurethane that provides excellent load-bearing capacity and wear resistance while still offering some cushioning. This hardness level is ideal for heavy-duty applications, providing durability and floor protection without excessive noise or vibration.

Can I mix fixed and swivel castors on the same equipment?

Yes, this is a common and recommended configuration. Typically, fixed castors are mounted at the rear for stability and straight-line tracking, while swivel castors are placed at the front for steering and manoeuvrability. This combination provides both directional control and ease of movement, making it ideal for trolleys, carts, and mobile equipment.
