Part of the IA IS Series range, used in Warehouse and Distribution Centres.
Key Benefits
- 45 kg working load and 50 kg maximum load per unit for stable handling of heavy flat items
- Bolt down disk mount with two screw holes allows secure attachment to a worktable or deck plate
- 12.7 mm diameter steel ball provides consistent rolling under load and high durability
- Steel or stainless steel case options suit dry, wet or washdown environments
- Nylon ball option protects painted or polished surfaces from marking during transfer
Application Scenarios
- Transfer points on a production line where flat panels or trays must be rotated or repositioned by hand
- Feeding systems in packaging machinery where trays are moved between stations without powered conveyance
- Processing tables for band saws, routers or CNC machines where workpieces are reoriented
- Assembly line stations where a fixture or component is turned manually between operations
- Material handling decks in automated systems where a flat load must be moved in any direction
Who It Is For
- Conveyor system integrators building manual transfer points into automated lines
- Industrial equipment builders constructing worktables and processing stations
- Packaging machinery manufacturers integrating transfer points into feeding systems
- Assembly line designers needing reliable manual repositioning of flat components
- Material handling equipment makers sourcing consistent ball transfer units by load and mount type
Problems It Solves
- Flat loads that jam or bind when pushed across a fixed deck due to lack of omnidirectional movement
- Transfer points where product must change direction without powered diverters or complex mechanisms
- Manual repositioning of heavy trays or panels that requires excessive force due to poor rolling effort
- Inconsistent mounting methods that lead to loose or misaligned units during operation
- Surface damage from steel balls on painted or polished workpieces during transfer
Technical Features
- 12.7 mm diameter steel ball provides consistent rolling under load and high wear resistance
- Bolt down disk mount with two screw holes allows secure, repeatable attachment to a deck plate
- Steel case with galvanized or chrome plating for corrosion resistance in industrial environments
- Stainless steel case option for wet, washdown or corrosive areas
- Nylon ball option available to prevent marking on sensitive surfaces
- Compact 50 mm diameter by 20 mm height design fits into tight deck spaces
Materials
- Carbon steel ball and case for general industrial use and high load capacity
- Galvanized or chrome plated case for improved corrosion resistance in humid environments
- Stainless steel case for washdown, food processing or corrosive areas
- Nylon ball for non-marking contact with painted, polished or sensitive surfaces
Quality Control
- Load capacity tested against the 45 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
- Mounting holes inspected for correct alignment and thread integrity
Customization Options
- Ball material selected between steel and nylon to suit surface protection needs
- Case material selected between carbon steel, galvanized, chrome plated or stainless steel
- Other IS Series load ratings available where 45 kg is not the right size
- Mounting holes can be adjusted for different deck thicknesses upon request
Use Guide
- Divide the total load by the number of units in contact to ensure each unit stays under the 45 kg working load
- Keep peak or impact loading below the 50 kg maximum load to prevent premature wear
- Mount the unit on a flat, rigid deck plate so all balls sit at the same height and roll freely
- Use the nylon ball when the load surface must not be marked or scratched
- Choose stainless steel case for environments with moisture, cleaning agents or corrosive materials

Manufacturing Process
Step 1
Machining of the disk base and mounting holes
Step 2

Step 3
Drilling and finishing of the bolt down disk for secure attachment
Step 4
Load test verification against the 45 kg working load rating
Step 5
Final inspection and packing for shipment
Compared With Other Options
| Press fit ball transfer units | Bolt down disk mount allows removal and replacement without damaging the deck, while press fit units are faster to install but harder to service |
|---|---|
| Lower rated IS Series units | The IS-13 suits 45 kg loads, so lighter applications are better served by a smaller unit that rolls with less effort |
| Swivel casters | Ball transfer units allow omnidirectional movement on a flat deck, while casters are designed for floor movement and are not suitable for fixed deck applications |
