Part of the SP Series range, used in Warehouse and Distribution Centres.
Key Benefits
- Carries 2000 kg per unit in normal service and 2500 kg at peak load
- Press mount fixes the unit into a deck plate with no need for bolts or flanges
- 76 mm diameter ball provides high load capacity for heavy flat items
- Steel, stainless steel or nylon ball options suit different surface and environment needs
- Steel, galvanized, chrome plated or stainless steel case options for durability and corrosion resistance
Application Scenarios
- Heavy tray transfer points on automated assembly lines where rotation is needed
- Flat panel handling stations in sheet metal or packaging equipment
- Curved work surfaces on band saws, routers or CNC machines requiring omnidirectional movement
- Feeding systems where large flat components must be repositioned by hand
- Processing machinery auxiliary tables needing stable, high-load transfer points
Who It Is For
- Conveyor system integrators building high-load transfer zones
- Industrial equipment builders requiring durable ball transfer units
- Assembly line designers for heavy flat part handling
- Material handling equipment makers building processing or feeding tables
- Industrial distributors stocking high-load ball transfer units by capacity
Problems It Solves
- Heavy flat loads that cannot be moved easily on fixed or low-capacity rollers
- Transfer points where product must be rotated or repositioned without powered guidance
- Need for a single high-load unit instead of multiple smaller units
- Lack of consistent material and load ratings across suppliers
- Deck plates that require a flush, non-bolted mounting solution
Technical Features
- 76 mm diameter main ball for high load capacity and stability
- Press mount design allows the unit to be pressed into a deck plate
- Fine machined ball seat ensures smooth rotation under heavy static load
- Main ball supplied in steel, stainless steel or nylon to match surface requirements
- Case supplied in steel, galvanized steel, chrome plated steel or stainless steel for environment suitability
- Unit weight of 10 kg 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
- Galvanized steel case for improved corrosion resistance in moderate environments
- Chrome plated steel case for wear resistance and appearance in high-use areas
Quality Control
- Load capacity verified against the 2000 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 correct fit into deck plate holes
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 2000 kg is not the right size
Use Guide
- Divide the total load by the number of units in contact to ensure no unit exceeds 2000 kg working load
- Keep peak and impact loading below the 2500 kg maximum load figure
- Press the unit into a deck plate with a hole sized to match the 130 mm mounting 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 units are faster to install and flush with the deck, but flange mount units can be removed and replaced without drilling new holes |
|---|---|
| Lower rated SP Series units | The SP-76 suits 2000 kg loads, so lighter decks 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 |
