- Industrial equipment builders designing workbenches with adjustable positioning
- Packaging machinery manufacturers needing smooth load rotation
- Material handling equipment makers installing ball transfer units in processing lines
- Industrial distributors stocking ball transfer units by load rating and mounting type
Problems It Solves
- Loads that stick or drag when moved across a fixed deck plate
- Transfer points where product must change direction without powered diverters
- Operators struggling to rotate or align a load by hand at the end of a line
- Inconsistent movement caused by mismatched ball height or loose mounting
- Marking of painted or polished surfaces due to hard steel ball contact

Use Guide
- Divide the load by the number of units in contact to ensure no more than 50 kg per unit
- Keep peak and impact loading below the 60 kg maximum load figure
- Mount units on a flat deck plate so all balls sit at the same height
- Choose the nylon ball where the load surface must not be marked
- Choose stainless steel ball and case where the deck is washed down or exposed to moisture

Compared With Other Options
| Flange mount ball transfer units | Stud mount uses two screws and is easier to remove for service, while flange mount bolts from above and is more secure for heavy decks |
|---|---|
| Lower rated D Series units | The D-6HR suits 50 kg loads, so lighter applications are better served by a smaller unit that rolls with less effort |
| Plain conveyor rollers | Ball transfer units allow movement in any direction, while rollers only move product along one axis |
