Select the right caster

How to proceed

Casters are like sand on the sea, endlessly different. It is therefore difficult to find the right castors for a construction or a project, and above all the right ones. The questions below should help you to make the right choice.

  1. Application site: Where should the caster be used?
  2. Place of use: Do special regulations exist at the place of use which must be observed (food industry, chemical laboratory etc.)?
  3. Application site: Do special environmental conditions exist at the application site (tropical climate, high salt content, etc.)?
  4. Load capacity: What is the maximum weight the roll should withstand?
  5. Material: Which material is required (stainless steel, ESD capable, high temperatures etc.)?
  6. Floor texture: What does the floor texture look like (industrial hall, parquet, carpet, gravel floor etc.)?
  7. Accessories: Which type of castor do you need (swivel castor, swivel castor with brakes, fixed castor)?
  8. Mass: Do specifications exist with regard to installation dimensions (height, fixing points, etc.)?

Assembly of casters

Fastening points

The mounting points of a caster are decisive for installation. A distinction is made between the following mounting options:

  • with plate
  • with pin
  • with back hole

For a caster with plate standard dimensions exist in the industry. In Europe, for example, this is a hole spacing of 80 x 60 mm. A machine manufacturer knows exactly how to dimension the fixing points on the machine so that a standard caster with plate fits perfectly. This makes the construction somewhat simpler. In furniture construction, the size of the panel does not play such a big role, since, for example, a caster with a panel can easily be attached to wood. In the medical sector, on the other hand, other panel sizes predominate. A caster with plate has four holes, which can be fastened to the corresponding object with four screws (example for a castor with special plate: heavy-duty castor ACMT-600F with minimum overall height).

A caster with pin (also called caster with threaded pin) does not require an additional screw for fastening, but the caster can be connected directly to the furniture or trolley using the threaded pin.

For a caster with back hole an additional screw is required with which the caster can be attached to the desired object (example: steering roller A 3202 with large back hole and low overall height).
