* When using a set of 4 castors, a safety derating factor applies. The combined rated load of 4 units (4 x 75kg = 300kg) is reduced to 225kg to account for uneven load distribution across all four mounting points.

Frequently Asked Questions

What surfaces are polypropylene castor wheels suitable for?

Polypropylene wheels perform best on smooth, hard floor surfaces such as concrete, tile, vinyl, laminate, and sealed timber. They are not recommended for heavily textured, uneven, or soft surfaces where a rubber or pneumatic wheel would be more appropriate. For indoor commercial and industrial environments with hard flooring, this wheel type offers an excellent balance of durability and rolling ease.

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

When fitting a set of 4 castors, the total safe working load is not simply 4 times the individual castor rating. A standard safety derating factor is applied to account for uneven load distribution ? typically resulting in a combined capacity of 75% of the theoretical maximum. For this castor, 4 units provide a combined safe working load of 225kg. Always ensure your total load (including the weight of the equipment itself) falls within this figure.

What fixings do I need to mount this castor?

This castor uses a 4-hole top plate measuring 60mm x 60mm, with hole centres of 48mm and 38mm and a hole diameter of 6mm. You will need four M6 bolts, washers, and nuts (or suitable self-tapping screws for timber applications) to secure the plate. Fixings are not included and should be selected based on the substrate material and thickness of the equipment being fitted.

Can this castor be used outdoors?

This castor is primarily designed for indoor use. The zinc-plated top plate offers a degree of corrosion resistance, but prolonged exposure to moisture, rain, or outdoor conditions may reduce the service life of the pressed steel components. For outdoor or wet-environment applications, a stainless steel or nylon-bodied castor with a suitable wheel material would be a more appropriate choice.

Our team brings deep product knowledge and a genuine commitment to reliable supply. If you need guidance on selecting the right castor for your specific application ? load, floor type, environment, or fitting method ? we are here to help you make the right choice with confidence.
