Key Benefits
- Carries 30 kg per unit in normal service and 40 kg at peak load
- Stud mount with M8 thread allows secure attachment to a deck plate with a tapped hole
- 25 mm diameter ball enables smooth movement of flat, rigid items across a deck
- Available with steel, stainless steel or nylon ball and multiple case finishes for different environments
- Compact size of 31 x 31 x 55 mm fits into tight deck layouts
Application Scenarios
- Transfer points between two conveyor lines where a tray must be rotated or repositioned by hand
- Assembly line stations where a fixture or tray is turned between operations
- Feeding systems in packaging or processing machinery where precise positioning is needed
- Workbenches with curved or angled surfaces where omnidirectional movement is required
- Deck sections where space is limited and a low-profile mounting solution is needed
Who It Is For
- Conveyor system integrators building transfer and rotation points into automated lines
- Material handling equipment builders designing tray handling or positioning decks
- Industrial distributors stocking ball transfer units by load and mounting type
- Production line builders needing consistent, low-friction movement for flat components
Problems It Solves
- Trays or fixtures that jam or bind when pushed 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
- Need for a compact, low-profile mounting solution in tight deck spaces
- Lack of consistent mounting and load rating across multiple component suppliers
Technical Features
- 25 mm diameter ball for smooth, omnidirectional movement of flat items
- Stud mount with M8 thread for secure attachment to a tapped hole in the deck
- Pressed ball housing with no machining, reducing cost and weight
- Ball and case materials selected from steel, stainless steel or nylon to suit the application
- Unit weight of 130 g for deck load and shipping calculations
Materials
- Carbon steel ball and case for general industrial use
- Stainless steel ball and case for wet, washdown or corrosive environments
- Nylon ball for non-marking contact with painted or polished surfaces
Quality Control
- Load capacity verified against the 30 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
- Stud thread inspected for correct M8 size and depth
Customization Options
- Ball material selected between steel, stainless steel and nylon
- Case material selected between steel & galvanized, steel & chrome plated, and stainless steel
- Other CY Series models available for different load ratings or mounting types
Use Guide
- Divide the load by the number of units in contact to ensure the 30 kg per unit rating is not exceeded
- Keep peak and impact loading below the 40 kg maximum load figure
- Mount the unit in a tapped hole so the stud is fully engaged and the case sits flush with the deck
- Choose the nylon ball where the load surface must not be marked
- Choose stainless steel ball and case where the deck is exposed to moisture or cleaning agents

Compared With Other Options
| Flange mount ball transfer units | Stud mount fits into a tapped hole and is more secure for high vibration environments, while flange mount allows easier removal for service |
|---|---|
| Pressed ball units with press fit mounting | Stud mount provides a more secure attachment than a press fit, especially under repeated loading |
| Lower rated CY Series units | The CY-25D suits 30 kg loads, so lighter applications are better served by a smaller unit that rolls with less effort |
