Key Benefits
- 200 kg working load and 250 kg maximum load per unit for heavy-duty handling
- Stud mount with M16 threaded hole allows secure attachment to a fixed deck plate
- 30.16 mm diameter ball enables smooth omnidirectional movement of flat items
- Multiple ball and case material options suit different environments and surface needs
- Compact size of 55 mm diameter and 66.5 mm height fits into tight deck spaces
Application Scenarios
- Transfer points on a conveyor line where a tray must be rotated or repositioned by hand
- Workbenches in packaging or assembly lines requiring 360-degree load movement
- Feeding systems where flat components need to be aligned or turned without powered guidance
- Processing machinery tables where tools or fixtures are moved laterally during operation
- Router tables or band saw setups requiring smooth, stable movement of flat stock
Who It Is For
- Conveyor system integrators building transfer and alignment points into production lines
- Industrial equipment builders designing worktables with manual load repositioning
- Packaging machinery manufacturers needing reliable ball transfer units for tray handling
- Assembly line builders integrating manual rotation or alignment stations
- Industrial distributors stocking ball transfer units by load and mounting type
Problems It Solves
- Flat loads that stick or drag when moved across a fixed deck plate due to high friction
- Need for manual repositioning of trays or fixtures without powered diverters
- Inconsistent movement caused by loose or poorly mounted transfer units
- Lack of a consistent range of stud mount units with matching load and mounting specs
- Difficulty in replacing units on a fixed deck when a press-fit or flange mount is not suitable
Technical Features
- Machined ball and housing for consistent fit and load distribution
- Stud mount with M16 threaded hole for secure, fixed installation on a deck plate
- 30.16 mm diameter ball allows smooth rolling of flat, smooth objects
- Omnidirectional movement enabled by a spherical ball inside a restraining fixture
- Two screw holes around the bearing for additional attachment security
Materials
- Carbon steel ball and case for general industrial use
- SUS304 stainless steel ball and case for wet or corrosive environments
- Nylon ball for non-marking contact with painted or polished surfaces
- Galvanized steel case for improved corrosion resistance in moderate environments
- Chrome plated steel case for a smoother finish and better wear resistance
Quality Control
- Load capacity verified against the 200 kg working load rating
- Ball rotation checked by hand for free movement in all directions
- Mounting hole thread inspected for correct M16 specification
- Material grade confirmed against the ball and case option ordered
- Unit weight measured to ensure 410 g tolerance
Customization Options
- Ball material selected between steel, stainless steel and nylon
- Case material selected between steel & galvanized, steel & chrome plated, or stainless steel
- Other SP Series models available for different load ratings and mounting types
- Mounting stud size can be adjusted if required for specific deck hole standards
Use Guide
- Ensure the deck plate has a properly sized M16 threaded hole for the stud mount
- Distribute the load across multiple units to stay within the 200 kg per unit working load
- Avoid using on uneven or soft-bottomed items such as cloth-wrapped goods
- Choose nylon ball if the load surface must not be marked
- Select stainless steel case for wet, washdown or high-corrosion environments

Manufacturing Process
Step 1
Machining of the case and ball housing

Step 3
Drilling and threading of the stud mount hole
Step 4
Surface treatment applied to case (galvanizing, chrome plating, or polishing)
Step 5
Load test and final inspection before packing
Compared With Other Options
| Flange mount ball transfer units | Stud mount is fixed via a threaded stud, while flange mount bolts from above; stud mount is better for decks with limited access from above |
|---|---|
| Press fit ball transfer units | Stud mount allows for removal and replacement without damaging the deck, unlike press fit which is harder to service |
| Lower load SP Series units | The SP-30FL suits 200 kg loads, so lighter applications may benefit from a smaller unit with less rolling resistance |
