Frequently Asked Questions
Which size should I choose — 50mm or 75mm?
The 50mm castor is best suited to lighter equipment and compact furniture where a lower overall height is preferred, with a load capacity of 65kg per castor (195kg for a set of four). The 75mm castor is the better choice for heavier or larger items, offering a 75kg per castor rating (225kg for a set of four) and a greater total height of 100mm, which improves rolling performance over minor floor irregularities. If your equipment is borderline in weight, always select the larger size to maintain an adequate safety margin.
Are these castors suitable for use on hard floors such as tile, laminate, or concrete?
Yes. The white nylon wheel is specifically designed for use on smooth, hard floor surfaces including ceramic tile, vinyl, laminate, polished concrete, and hardwood. Nylon offers excellent rolling resistance and durability on these surfaces. It is not recommended for use on soft or carpeted floors, as the hard wheel will not roll freely and may cause damage to delicate floor coverings.
How do I calculate the correct load capacity I need?
To determine the required load capacity per castor, divide the total weight of the equipment — including its maximum contents — by the number of castors being fitted (typically four). For example, a trolley with a maximum loaded weight of 200kg fitted with four castors requires each castor to support 50kg. Always add a safety margin of at least 25–30% above the calculated figure to account for dynamic loads, uneven weight distribution, and floor surface variations. On this basis, the 65kg-rated 50mm castor would be appropriate for that example.
How are these castors fitted, and what fixings are required?
Both the 50mm and 75mm castors are fitted using a four-hole pressed steel top plate measuring 60mm x 60mm. The plate features dual hole-centre dimensions of 48mm and 38mm (length and width), providing compatibility with a wide range of equipment bases. The fixing holes have a diameter of 6mm, accepting standard M6 bolts or equivalent fasteners. No specialist tools are required — a standard spanner or socket set is sufficient for installation. Ensure the mounting surface is flat, rigid, and of adequate thickness to support the intended load.
* Load ratings stated are per individual castor under static conditions on a flat, level surface. Always calculate total equipment weight including maximum contents and divide by the number of castors fitted. Apply a minimum safety margin of 25% above the calculated figure. These castors are intended for use on smooth, hard floor surfaces only.
