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 directional stability and controlled movement. Swivel castors rotate 360 degrees, offering greater manoeuvrability. Fixed castors are typically used in pairs with swivel castors to balance stability and steering capability.
Will this castor mark my floors?
No, the grey thermoplastic rubber wheel is specifically designed to be non-marking, making it safe for use on polished concrete, vinyl, laminate, tile, and other sensitive floor surfaces commonly found in retail and commercial environments.
How do I calculate the total load capacity for my trolley?
Multiply the load capacity of a single castor (100kg) by the number of castors you plan to install. For example, four castors would provide a total capacity of 400kg. Always distribute weight evenly and include a safety margin for dynamic loads and uneven surfaces.
What fixings do I need to install this castor?
You will need four bolts or screws with an 8mm diameter (or M8 bolts) to fit through the mounting holes. The length depends on your base material thickness. Ensure fixings are appropriate for your application and material type for secure installation.
Can this castor be used outdoors?
While the zinc-plated construction offers some corrosion resistance, this castor is primarily designed for indoor retail and commercial use. For outdoor applications or harsh environments, consider castors with enhanced weatherproofing and corrosion protection.
What does 88 Shore A hardness mean?
Shore A hardness measures the firmness of rubber materials. An 88 Shore A rating indicates a relatively firm rubber that provides excellent durability and load support while still offering good floor protection and noise reduction. This hardness level is ideal for medium-duty applications.
How do I maintain these castors?
Regularly inspect castors for wear, damage, or debris buildup. Clean wheels with a damp cloth to remove dirt and debris. Check mounting bolts periodically to ensure they remain tight. Lubricate plain bearings occasionally with light machine oil to maintain smooth operation.
What is the total height added to my equipment?
The total castor height is 162mm, which is the distance from the floor to the top of the mounting plate. This measurement helps you determine the final height of your equipment once the castors are installed.
