Part of the SP Series range, used in Warehouse and Distribution Centres.
Key Benefits
- Carries 450 kg per unit in normal service and 500 kg at peak load
- Press mount fixes the unit into a deck plate with no external fasteners
- 45 mm diameter ball provides stable support for heavy flat loads
- Steel, stainless steel or nylon ball options suit different surface and environment needs
- Case options include galvanized, chrome plated or stainless steel for corrosion resistance
Application Scenarios
- Transfer points between two straight conveyor lines where product must change direction
- Assembly stations where a heavy panel or tray needs to be rotated by hand
- Packaging lines where flat containers are repositioned for labeling or sealing
- Machine feeding tables where a flat workpiece is aligned before processing
- Processing machinery where a large flat component is moved between operations
Who It Is For
- Conveyor system integrators building high-load transfer points
- Material handling equipment builders designing flat deck transfer zones
- Industrial automation contractors installing manual rotation points
- Production line builders needing consistent load ratings across a system
- Industrial distributors stocking ball transfer units by load and mounting type
Problems It Solves
- Heavy flat loads that jam when pushed across a fixed deck plate
- Transfer points where product must change direction without powered diverters
- Operators struggling to rotate or align a heavy panel by hand at the end of a line
- Inconsistent mounting methods that lead to loose or misaligned units
- Lack of a single supplier for ball transfer units with matching load and mounting type
Technical Features
- 45 mm diameter main ball for high load capacity and stability
- Press mount design allows direct insertion into a deck plate without bolts
- Fine machined ball seat ensures smooth rotation under heavy static load
- Main ball available in steel, stainless steel or nylon to match surface requirements
- Case available in steel, galvanized steel, chrome plated steel or stainless steel for durability
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
- Galvanized or chrome plated case for improved corrosion resistance in dry areas
Quality Control
- Load capacity verified against the 450 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
- Press fit dimensions checked to ensure proper insertion into deck plate
Customization Options
- Ball material selected between steel, stainless steel and nylon
- Case material selected between steel, galvanized, chrome plated and stainless steel
- Other SP Series load ratings available where 450 kg is not the right size
Use Guide
- Divide the load by the number of units in contact to ensure the 450 kg per unit rating is not exceeded
- Keep peak and impact loading below the 500 kg maximum load figure
- Press the unit into a flat, smooth deck plate with a clearance hole of 62 mm diameter
- 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

Compared With Other Options
| Flange mount ball transfer units | Press mount requires no bolts and fits flush with the deck, while flange mount allows easier removal for maintenance |
|---|---|
| Lower rated SP Series units | The SP-45 suits 450 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 |
