Ball Units Load Requirements

Correct ball unit selection is important for any project, and choosing a unit with sufficient load capacity is key to this. 

Load capacity required per ball unit

A minimum of 3 ball units should be in contact with the load at any time, therefore load ÷ 3 = load per ball unit.

However on a totally level surface, this number may often be more in practice. 

NOTE: Reduced Load Capacities apply for some ball units when used in a ball down position or any other angle apart from Ball Up. 

Spacing / pitch between ball units (ball up use only)

Correct spacing ensures that at least 3 ball units are beneath the narrowest part of the load at any one time. Calculate spacing as follows:

Smallest dimension of load ÷ 3.5 = spacing between ball centres (pitch)

e.g. 350mm ÷ 3.5 = 100mm pitch

Depending on the shape of the article to be conveyed, either a square, diamond, or elongated pitch can be used as appropriate.

What is the Ball Unit Identifier?

The Alwayse Ball Unit Identifier allows you quickly identify suitable units based on 2 key criteria. By choosing from the options listed you will be given a variety of ball transfer products which meet your needs.

If you know the Alwayse part number enter it and you will be taken directly to the appropriate information. You can also enter other companies’ part numbers to find the Alwayse equivalent.

Fixing Method

Choose the appropriate fixing for your application if known.

Load Capacity

Choose the maximum load capacity required. Please note that these are for a load up orientation. For load down or other orientations please note that the maximum load capacity may be reduced.
