Frequently Asked Questions
How do I choose the right wheel diameter for my application?
As a general rule, a larger wheel diameter rolls more easily over longer distances and minor floor irregularities, while a smaller diameter is better suited to compact equipment in confined spaces. For light-duty retail or office use, the 80mm or 100mm options are typically sufficient. For warehouse trolleys and industrial carts carrying heavier loads, the 125mm, 150mm, or 200mm sizes offer greater rolling efficiency and load capacity. Always verify that the total castor height is compatible with the clearance available on your equipment frame before ordering.
What does the directional brake do, and how does it work?
The directional brake is a foot-operated mechanism that locks the wheel in a fixed position, preventing the castor from rolling when engaged. Unlike a total-lock brake — which also locks the swivel head — a directional brake allows the castor to continue swivelling freely while the wheel itself is held stationary. This is particularly useful on trolleys and carts where you want to prevent unintended movement without fully immobilising the unit. To engage, press the brake lever down with your foot; to release, lift it back to the open position.
Are these castors suitable for use on hard floors such as concrete, tile, or vinyl?
Yes. White nylon wheels with an 85 Shore A hardness rating are well-suited to smooth, hard floor surfaces including concrete, ceramic tile, vinyl, and sealed timber. The hard tread rolls efficiently with minimal resistance on these surfaces and does not leave marks or deposits. Nylon wheels are not recommended for use on soft or delicate flooring — where a softer polyurethane tread would be more appropriate — or on surfaces with significant debris or grit that could cause premature wear.
How do I calculate the total load capacity I need?
Divide the total weight of the fully loaded equipment — including its contents — by the number of castors being fitted, typically four. For example, a trolley with a total loaded weight of 480kg fitted with four castors requires each castor to be rated to at least 120kg. It is good practice to select a castor with a load rating above the calculated minimum to allow for dynamic loading, uneven weight distribution, and floor surface variations. The maximum combined load ratings for four castors in this range are: 360kg (80mm), 420kg (100mm), 480kg (125mm), 540kg (150mm), and 690kg (200mm).
