Guidance on the Characteristics of Industrial Castors

Conceptually we are used to a castor as a mechanical assembly which lets us to replace sliding motion by rolling motion, often with an inbuilt turning mechanism to permit both easy forward movement as well as modest changes of direction.

It is valuable to consider the ubiquitous castor in its elements and to identify the characteristics of those elements as well as the results of their interactions in order to optimally stipulate a castor installation. We use the following international standards, nomenclature and characteristic descriptions to aid our customer references.You can visit hovair.com/information-files/machine-machinery-skates.htm to get load moving equipments.

• Tread

The tread is the wheel's outer surface, i.e. the part that comes in contact with the ground. It can be smooth or etched with raised patterns to increase its grip on the ground.

• Covering

The covering, or rolling strip, is the outer ring. It is made of different materials and characterizes the appearance of the wheel. The covering is secure when joined with the wheel centre body as a single solid piece (using an adhesive or through a mechanical connection) or fitted when mechanically assembled on the wheel centre body.

• Wheel centre body

The wheel centre body is the wheel part that connects the covering to the bore. It comes in numerous shapes and is made of different materials; it can be a single piece or two or more parts joined together.
