Key Benefits
- Carries 5 kg per unit in normal service and 6 kg at peak load
- Stud mount with M6 thread allows secure attachment to a tapped hole in a worktable
- Fine machined ball and seat reduce rolling resistance under light load
- Nylon ball option protects painted or polished surfaces from marking
- Stainless steel ball and case option for use in wet or washdown environments
Application Scenarios
- Transfer points on a flat worktable where a tray or panel must be moved in any direction
- Feeding systems in packaging machinery where a flat item needs to be repositioned
- Processing machinery with a curved work surface requiring omnidirectional movement
- Assembly stations where a fixture is rotated by hand between operations
- Conveyor integration points where a light load must be transferred between lines
Who It Is For
- Conveyor system integrators building light-duty transfer points
- Material handling equipment builders designing worktables with movable decks
- Industrial distributors stocking ball transfer units by load rating
- Assembly line builders needing low-friction movement for small components
Problems It Solves
- Light loads that stick or drag when pushed across a fixed deck plate
- Transfer points where a flat item must be repositioned without powered guidance
- Operators struggling to align a small panel or tray by hand at a workbench
- Worktables requiring a compact, low-profile mounting solution with minimal deck penetration
Technical Features
- Fine machined ball and seat for consistent rolling under light static load
- Stud mount with M6 thread for secure attachment to a tapped hole
- Ball diameter of 6.35 mm (0.25 inch) for precise fit and smooth motion
- Case and ball materials selected from steel or stainless steel to suit environment
- Unit weight of 35 g for deck load and shipping calculations
Materials
- Nylon ball for non marking contact with painted or polished surfaces
- Carbon steel ball and case for general industrial use
- Stainless steel ball and case for wet, washdown or corrosive environments
Quality Control
- Load capacity checked against the 5 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 5 kg is not the right size
Use Guide
- Divide the load by the number of units in contact to check the 5 kg per unit rating
- Keep peak and impact loading below the 6 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 fits into a tapped hole and is more compact, while flange mount bolts from above and allows easier removal |
|---|---|
| Lower rated D Series units | The D-2H suits 5 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 |
