The unit weighs 20 g and is available with steel, stainless steel or nylon balls in steel, galvanized steel, chrome-plated steel or stainless steel cases.
Part of the SP Series range, used in Warehouse and Distribution Centres.
Key Benefits
- Carries 8 kg per unit in normal service and 15 kg at peak load
- Stud mount with M5 thread allows secure attachment to worktables and benches
- Fine machined ball and housing reduce rolling resistance under light load
- Steel, stainless steel or nylon ball options suit different surface protection needs
- Multiple case materials for dry, wet or corrosive environments
Application Scenarios
- Transfer points on assembly lines where small trays or components need to be repositioned
- Feeding systems in packaging machinery requiring smooth, omnidirectional movement
- Processing tables where light parts are rotated or aligned by hand
- Workbenches with fixed mounting points for consistent ball transfer unit placement
- Curved work surfaces on router tables or band saws where directional change is needed
Who It Is For
- Conveyor system integrators building light-duty transfer zones
- Packaging machinery builders needing small omnidirectional transfer points
- Industrial equipment makers integrating ball transfer units into workstations
- Production line designers for small part handling with fixed mounting options
Problems It Solves
- Light loads that stick or drag when moved across a fixed surface
- Need for directional change in a small footprint without powered diverters
- Inconsistent mounting methods that lead to loose or misaligned units
- Surface damage from hard balls on painted or polished work surfaces
- Lack of compact, stud-mounted units for tight workbench installations
Technical Features
- 8 mm diameter ball with fine machined seat for smooth rotation under light load
- Stud mount with M5 thread for direct screw attachment to worktables
- Ball material selected from steel, stainless steel or nylon to suit surface contact
- Case material available in steel, galvanized steel, chrome-plated steel or stainless steel
- Compact dimensions of 20 mm diameter and 23.1 mm height for space-constrained setups
Materials
- Steel ball for general light-duty use with standard work surfaces
- Stainless steel ball for wet or corrosive environments
- Nylon ball to protect painted, polished or soft surfaces from marking
- Steel case for standard industrial use
- Galvanized or chrome-plated steel case for improved corrosion resistance
Quality Control
- Load capacity verified against the 8 kg working load rating
- 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 M5 size and engagement
Customization Options
- Ball material selected between steel, stainless steel and nylon
- Case material selected between steel, galvanized steel, chrome-plated steel and stainless steel
- Other SP Series models available for different load ratings or mounting styles
Use Guide
- Ensure the load per unit does not exceed 8 kg in normal operation
- Keep peak or impact loading below the 15 kg maximum load limit
- Mount the unit on a flat, rigid surface so the ball sits level with adjacent units
- Use nylon ball when the load surface must not be marked or scratched
- Choose stainless steel case and ball for washdown or high-moisture environments

Compared With Other Options
| Flange mount ball transfer units | Stud mount SP-8FL is faster to install on pre-drilled tables, while flange mount allows easier removal for maintenance |
|---|---|
| Press fit ball transfer units | Stud mount provides a more secure attachment than press fit, especially under vibration or repeated use |
| Higher load SP Series units | The SP-8FL is designed for 8 kg loads, so heavier applications require a larger model with higher capacity |
