Frequently Asked Questions
What is the difference between a fixed castor and a swivel castor?
A fixed castor only moves in a straight line, providing stable directional movement ideal for the rear of trolleys or equipment that travels along defined paths. Swivel castors rotate 360 degrees, offering manoeuvrability and are typically used on the front of equipment for steering.
How much weight can this castor support?
Each castor has a load capacity of 160 kg. When using four castors on a trolley or cart, the combined maximum load capacity is 480 kg. Always distribute weight evenly across all castors for optimal performance and safety.
Is this castor suitable for use on smooth floors?
Yes, the polyurethane on nylon wheel with 85 Shore A hardness is specifically designed to protect smooth floor surfaces including tiles, polished concrete, and epoxy coatings. The material provides excellent grip while minimising floor marking and damage.
How do I install this top plate castor?
The castor features a 100mm × 85mm top plate with four 10mm diameter mounting holes positioned at 60mm × 80mm centres. Simply align the plate with your equipment base, mark the hole positions, drill pilot holes, and secure using appropriate bolts or screws (not included).
What type of bearing does this castor use?
This castor is equipped with a ball journal bearing, which provides smooth, low-friction rolling performance under load. Ball bearings are ideal for medium to heavy-duty applications, offering durability and consistent operation over extended use.
Can this castor be used outdoors?
This castor is primarily designed for indoor use in commercial and industrial environments. While the pressed steel construction and polyurethane wheel are durable, prolonged outdoor exposure to moisture and weather may affect longevity. For outdoor applications, consider castors with additional corrosion protection.
What is the total height of this castor?
The total castor height from the base of the wheel to the top of the mounting plate is 157mm. This measurement is important when calculating ground clearance for your trolley or equipment.
