Part of the KS KSM Series range, used in Warehouse and Distribution Centres.
Key Benefits
- 100 kg working load and 150 kg maximum load per unit for consistent handling of flat loads
- Spring loaded design maintains ball contact under load and compensates for minor deck surface variations
- Press mount installation allows fast, secure fit into a 44 mm hole without bolts or flanges
- 25.4 mm (1 inch) diameter ball provides stable rolling for trays, panels and rigid components
- Available in carbon steel, galvanized steel, chrome plated steel or stainless steel for different environment needs
Application Scenarios
- Transfer points in a flat belt conveyor line where trays or panels need to be rotated or repositioned
- Assembly line feeders where rigid components are moved laterally between stations
- Packaging machinery where flat containers are aligned or turned before sealing or labeling
- Sheet metal processing lines where panels are shifted between cutting, bending or drilling stations
- Router tables and band saw workstations requiring smooth, omni-directional movement of flat parts
Who It Is For
- Conveyor system integrators building transfer and alignment points in automated lines
- Material handling equipment builders designing flat decks for rotating or repositioning loads
- Industrial automation contractors installing feed systems for packaging, assembly or processing
- Sheet metal and fabrication shops moving panels between machines without powered transfer
- Industrial distributors stocking ball transfer units by load and mounting type
Problems It Solves
- Flat loads that stick or jam 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
- Decks with uneven surfaces where standard ball units lose contact and create drag
- Need for fast, tool-free installation of ball transfer units in production line upgrades
- Lack of consistent load rating across units from multiple suppliers in a single system
Technical Features
- Spring loaded mechanism maintains ball contact under load and improves stability
- 25.4 mm (1 inch) diameter steel ball allows smooth rolling of flat, rigid items
- Press mount design fits into a 44 mm hole in the deck plate without additional fasteners
- Housing made from carbon steel, galvanized steel, chrome plated steel or stainless steel (SUS304)
- Steel ball material ensures durability and consistent performance under repeated load cycles
- Unit weight of 390 g for deck load and shipping calculations
Materials
- Carbon steel case and ball for general industrial use and cost-effective performance
- Galvanized steel case for improved corrosion resistance in humid environments
- Chrome plated steel case for enhanced wear resistance and a smoother surface
- Stainless steel (SUS304) case and ball for washdown, food processing or corrosive areas
Quality Control
- Load capacity verified against the 100 kg working load rating before packing
- Ball rotation checked by hand for free movement in all directions
- Material grade confirmed against the case and ball option ordered
- Press fit dimension checked to ensure 44 mm mounting hole compatibility
Customization Options
- Case material selected between carbon steel, galvanized steel, chrome plated steel or stainless steel (SUS304)
- Ball material is steel for all models; no nylon or stainless steel ball option available
- Other KSH Series models available for different load ratings or mounting styles
Use Guide
- Ensure the deck plate has a 44 mm hole for press fit installation
- Check that the load per unit does not exceed 100 kg during normal operation
- Keep peak and impact loads below the 150 kg maximum load rating
- Use only on flat, rigid surfaces such as trays, panels or pallets
- Avoid use on soft, uneven or flexible surfaces like cloth-wrapped items or foam

Compared With Other Options
| Flange mount ball transfer units | Press mount units install faster without bolts but are harder to remove or replace after installation |
|---|---|
| Non-spring loaded units | Spring loaded design maintains ball contact under load and handles minor deck imperfections better |
| Lower rated KSH Series units | The KSH-30 suits 100 kg loads, so lighter applications are better served by smaller units with less rolling resistance |
