Mounting the plate fitting
Depending on the design of the equipment to which the casters are to be attached, different types of fitting are used.
The caster is mounted using nuts and bolts to a flat surface on the equipment. The mounting plate is located on the top of the caster. The dimensions of the plate and the area on the equipment to which it is to be attached are standardized and proportional to the diameter of the caster or wheel. The standard spacing between the holes is, for example, 80 x 60 mm for a diameter of 80 to 100 mm, and 105 x 80 mm for a diameter of 125 mm. The following dimensions must be taken into account when selecting the appropriate plate fitting:
+ Plate size
+ Bolt-hole spacing
+ Bolt-hole diameter
When mounting a plate fitting it is important that the caster and the equipment, or apparatus, are flush with each other. The equipment must rest exactly on the outer ball cover if the caster is to achieve its maximum load capacity and ensure long-term functionality.
