Part of the SP Series range, used in Warehouse and Distribution Centres.
Key Benefits
- Carries 3000 kg per unit in normal service and 3500 kg at peak load
- Press mount fixes the unit into a deck plate with no need for bolts or flanges
- 90 mm diameter ball provides high load capacity for heavy flat items
- Fine machined ball and seat allow smooth rotation under heavy static load
- Multiple ball and case material options suit dry, wet or sensitive surface environments
Application Scenarios
- Heavy transfer points in industrial assembly lines where large panels or trays are rotated
- Feeding systems in packaging or processing machinery requiring omnidirectional movement
- Curved work surfaces on band saws, router tables or CNC machines where items must pivot
- Conveyor transfer decks between lines running at different angles or speeds
- Material handling stations where flat, rigid items are repositioned by hand
Who It Is For
- Conveyor system integrators building high-load transfer and rotation points
- Industrial equipment builders designing feeding or processing tables
- Assembly line engineers needing omnidirectional movement for large components
- Material handling contractors installing transfer decks in production lines
- Manufacturers of processing machinery requiring stable, high-capacity ball transfer
Problems It Solves
- Heavy flat items that jam or bind when pushed across a fixed deck plate
- Transfer points where product must change direction without powered diverters
- Operators struggling to rotate or align large panels by hand at the end of a line
- Decks requiring consistent load capacity across multiple transfer points
- Need for a single component that replaces multiple rollers or casters in a fixed deck
Technical Features
- 90 mm diameter main ball for high load capacity and stability under heavy static load
- Press mount design allows direct insertion into a deck plate without bolts
- Fine machined ball seat and ball ensure smooth rotation even under full load
- Main ball available in steel, stainless steel or nylon to suit surface contact needs
- Case available in carbon steel, galvanized steel, chrome plated steel or stainless steel
Materials
- Steel ball and case for general industrial use with high load capacity
- Stainless steel ball and case for wet, washdown or corrosive environments
- Nylon ball for non-marking contact with painted, polished or sensitive surfaces
- Galvanized steel case for improved corrosion resistance in moderate environments
- Chrome plated steel case for enhanced wear resistance and appearance
Quality Control
- Load capacity verified against the 3000 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
- Press fit surface inspected for smoothness and correct diameter
Customization Options
- Ball material selected between steel, stainless steel and nylon
- Case material selected between carbon steel, galvanized steel, chrome plated steel and stainless steel
- Other SP Series load ratings available where 3000 kg is not the right size
Use Guide
- Divide the total load by the number of units in contact to ensure no more than 3000 kg per unit
- Keep peak and impact loading below the 3500 kg maximum load figure
- Press the unit into a flat, smooth deck plate with a hole sized to the 145 mm mount 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 washdown or moisture

Manufacturing Process
Step 1

Step 2
Assembly of the main ball and support ball with proper clearance
Step 3
Press fit preparation of the mounting surface for deck insertion
Step 4
Final inspection of ball rotation and load capacity before packing
Compared With Other Options
| Flange mount ball transfer units | Press mount units are faster to install and require no bolts, but flange mount units can be removed and replaced without drilling new holes |
|---|---|
| Lower rated SP Series units | The SP-90 suits 3000 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 |
Press Mount Machined Ball Transfer Unit SP-90 Questions
What load can one SP-90 ball transfer unit carry?
The rated load capacity is 3000 kg per unit and the maximum load capacity is 3500 kg.
How is the SP-90 mounted?
It is a press mount unit, so it is pressed directly into a hole in the deck plate.
Which ball material should I choose?
Steel for general use, stainless steel for wet or corrosive areas, nylon to protect painted or polished surfaces.
Is a stainless steel version available?
Yes, both the ball and the case can be supplied in stainless steel.
How much does the unit weigh?
Each SP-90 weighs 12 kg, which is used for deck load and shipping calculations.
Can I get other load ratings in the same series?
Yes, the SP Series covers other load ratings, so ask for the model that matches your load per unit.
