SELECTING THE RIGHT UNIT - QUANTITY & CAPACITY
High capacity  Medium duty Light duty
Consideration must be given to the spacing and loading of units, and the method of mounting.
The load capacity of ball transfer units is optimized when all the units are flat, horizontal, and the conveyed goods have a suficiently hard carrying surface. (The surface of the item to be transferred must be capable of withstanding brinelling under load.) Therefore, depending on the condition of the conveyor or of the conveyed goods, the quantity of ball transfer units may need to be increased.
When assessing the quantity and capacity of Omnitrack units required for any installation it is recommended that a safety factor of 3 is allowed.
To determine ball units' capacity, the weight of the article to be conveyed should be divided by 3. The result gives the maximum load which any single ball transfer unit may have to support.

PEAK TEMPERATURE RANGE
High capacity - Autotrack range from -30°C to 100°C
Medium duty - Metric range from -10°C to 50°C
Light duty - General range from -10°C to 40°C

The distance between the ball units depends upon the sizes and shape of the items to be transferred. The maximum distance between ball transfer units should not be grater than 33% of the item's smallest dimension in the transfer plane. This will ensure that there will be 3 units always supporting the smallest dimension.
