What fixed castors are for

A fixed castor, also called a rigid castor, has a fork that does not swivel, so it rolls only forwards and backwards. On its own it cannot steer a trolley. Together with swivel castors it keeps the trolley on track, so it runs straight on long runs without constant correction. We press the forks in Postojna from sheet steel and zinc plate them without chromium(VI).

With two fixed castors, the trolley is pushed from the swivel castor end. The brakes go there too, where the foot reaches the pedal.

Matching fixed and swivel castors

On one trolley, fixed and swivel castors should share the same wheel: same diameter, same tread, same load capacity. Check the overall height in the specifications as well. If the heights differ, the trolley rocks and one castor carries more than its share. A top plate with the same hole pattern means one drilling pattern for both castors.

Wheel, bearing and load capacity

Choose wheel and bearing as for the swivel castor. Elastic rubber and polyurethane protect smooth factory floors; polyamide and cast iron carry more but are hard. A ball bearing pays off when the trolley is pushed often and far. The catalogue load capacity is per castor at 4 km/h; with four castors, divide the weight of trolley plus load by three. For high loads, the heavy duty range includes fixed castors.

Fixed castors with brake or central brake

Usually the braked swivel castors hold the trolley. Where that is not enough, for example on equipment without swivel castors, we make fixed castors with a brake and with a central brake as special versions. Ask us with the load, wheel diameter and fitting. If you are replacing a castor, send us the drawing or the dimensions and we confirm the match.

Frequently asked questions

What is a fixed castor?

A castor with a rigid fork that does not swivel, also called a rigid castor. It rolls only straight and keeps a trolley on track.

Where do fixed castors go on a trolley?

Usually two fixed castors at the end away from the handle and two swivel castors at the handle end. The trolley then runs straight and still turns.

Are fixed castors available with a brake?

Yes, as special versions with a brake and with a central brake. Ask us with the load, wheel diameter and fitting.

What should I check when combining fixed and swivel castors?

Both should have the same wheel, the same overall height and the same top plate hole pattern. Otherwise the trolley rocks and one castor carries more than intended.

What load capacity do I need per fixed castor?

Divide the weight of the trolley plus load by three when four castors are fitted. The catalogue figure is per castor at 4 km/h.
