A firm connection

Between the castor and the equipment a good and firm connection has to be made. The type of attachment and the dimensions dependent on the application and equipment. Various forces can be of influence on the fixing unit.

When assembling you should make sure that the castor is mounted against a flat and firm surface, to ensure a rigid support for the complete top plate area of our castors. Only then the given load ratings (capacities) apply.

The following types of connections can be used:

Central bolt hole fitting

The assembly of the castor takes place with a screw through the center of the hole in the swivel head. Pay attention! The specified load capacities only apply if the mounting plate of the castor is completely and evenly loaded.

Threaded pin fitting

Here, the swivel fork is equipped with a threaded pin that comes out of the central part of the swivel head. This threaded pin is screwed into a internal thread hole of a trolley or machine. Threaded pin fittings are mainly used for furniture or institutional devices (lighter applications).

Expanders (fitting for tubes)

The wheel is mounted, through a (plastic and / or metal) expander in a round (EXR), or square (EXV) pipe of a trolley or machine. By tightening the bolt the plastic and / or metal element expands and is clamped against the inside of the tube.

Mounting Plate fitting

The assembly of the castor takes place, through a plate fastened by bolts and nuts against a flat surface. The dimensions of the bolt holes are ISO normalized. Mounting plate fitting is available for swivel and fixed castors. Castors with a directional lock must be mounted to the plate with the short side facing the trailing direction.
