- Nylon ball option protects painted or polished surfaces from marking
- Stainless steel ball and case option for wet, washdown or corrosive environments
Application Scenarios
- Transfer points on a flat deck where trays or flat components need to be moved in any direction
- Workbenches in assembly lines where a fixture must be repositioned by hand
- Feeding systems in packaging or processing machinery where flat items are aligned
- Curved work surfaces on router tables or band saws requiring omnidirectional movement
- Material handling decks where multiple units are used to move heavy flat loads
Who It Is For
- Conveyor system integrators building transfer decks with stud-mounted ball units
- Industrial equipment builders designing workbenches with manual repositioning
- Packaging and processing machinery manufacturers needing omnidirectional transfer
- Material handling equipment makers building flat decks for tray or panel handling
- Industrial distributors stocking ball transfer units by load rating and mounting type
Problems It Solves
- Flat loads that cannot be rotated or repositioned easily on a fixed deck
- Transfer points where product must change direction without powered diverters
- Operators struggling to push or align heavy flat items by hand
- Decks requiring multiple units with consistent load rating and mounting size
- Workbenches needing secure attachment without press-fit installation
Technical Features
- Fine machined ball and seat rather than a pressed or stamped housing
- Stud mount with M10 diameter for secure bolted attachment to the deck
- Main ball supplied in nylon, steel or stainless steel to suit the load surface
- Case supplied in steel or stainless steel for dry or wet environments
- Unit weight of 230 g for deck load and shipping calculations
Materials
- Nylon main ball for non marking contact with painted or polished surfaces
- Carbon steel ball and case for general industrial decks
- Stainless steel ball and case for wet, washdown or corrosive areas
Quality Control
- Load capacity checked against the 100 kg rating before packing
- Ball rotation checked by hand for free movement in all directions
- Material grade confirmed against the ball and case option ordered
Customization Options
- Ball material selected between nylon, steel and stainless steel
- Case material selected between steel and stainless steel
- Other D Series load ratings available where 100 kg is not the right size
Use Guide
- Divide the load by the number of units in contact to check the 100 kg per unit rating
- Keep peak and impact loading below the 150 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

Compared With Other Options
| Flange mount ball transfer units | Stud mount bolts through the deck and allows easier removal for service, while flange mount is fixed from above |
|---|---|
| Lower rated D Series units | The D-8HN suits 100 kg loads, so lighter decks 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 |
