Part of the SP Series range, used in Warehouse and Distribution Centres.
Key Benefits
- Carries 140 kg per unit in normal service and 160 kg at peak load
- Stud mount with M10mm thread allows secure attachment to workbenches and decks
- Two screw holes around the housing provide strong, stable mounting
- Fine machined ball and seat reduce rolling resistance under load
- Available in nylon ball to protect delicate surfaces or stainless steel for wet environments
Application Scenarios
- Transfer points on a flat workbench where trays or flat components need to be repositioned in any direction
- Assembly lines with rotating stations where a fixture must be turned by hand
- Packaging machinery where flat items are aligned or rotated before sealing
- Feeding systems where flat parts are moved between processing stations
- Router tables or band saws where material needs to be shifted smoothly in all directions
Who It Is For
- Conveyor system integrators building manual transfer or rotation points
- Industrial equipment builders designing workbenches with omnidirectional movement
- Assembly line engineers adding hand-rotatable stations for part alignment
- Packaging machinery manufacturers integrating flat item positioning systems
- Industrial distributors stocking ball transfer units by load and mounting type
Problems It Solves
- Flat items that stick or drag when pushed across a fixed deck due to friction
- Workstations where a part must be rotated or repositioned without powered assistance
- Mounting systems that loosen over time due to vibration or repeated load
- Workbenches requiring multiple transfer points with consistent load capacity
- Surface damage from steel balls on painted or polished work surfaces
Technical Features
- Machined ball and housing for consistent fit and low rolling effort
- Stud mount with M10mm thread and two surrounding screw holes for secure attachment
- 22.23 mm diameter ball for compatibility with standard deck hole sizes
- Ball and case materials selected independently to suit the application environment
- Unit weight of 250 g for deck load and shipping planning
Materials
- Steel ball and case for general industrial use and high load applications
- Stainless steel ball and case for wet, washdown or corrosive environments
- Nylon ball for non-marking contact with painted, polished or sensitive surfaces
Quality Control
- Load capacity tested against the 140 kg working load 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 M10mm size and depth
- Mounting holes checked for alignment and clearance
Customization Options
- Ball material selected between steel, stainless steel and nylon
- Case material selected between steel & galvanized, steel & chrome plated, and stainless steel
- Other SP Series models available for different load ratings or mounting styles
Use Guide
- Divide the load by the number of units in contact to ensure no unit exceeds 140 kg working load
- Keep peak and impact loading below the 160 kg maximum load figure
- Mount the unit on a flat, rigid deck plate so all balls sit at the same height
- Choose 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

Compared With Other Options
| Flange mount ball transfer units | Stud mount is faster to install on a pre-drilled deck, while flange mount allows easier removal for maintenance |
|---|---|
| Press fit ball transfer units | Stud mount provides a more secure attachment and can be removed without damaging the deck, unlike press fit units |
| Lower rated SP Series units | The SP-22FL suits 140 kg loads, so lighter applications are better served by smaller units with less rolling resistance |
