The unit weighs 768 g and is available with a steel, galvanized steel, chrome plated steel or stainless steel case.
Product Overview
The KSF-30 is a spring loaded press mount ball transfer unit with a 30 mm diameter steel ball, rated for 100 kg working load and 150 kg maximum load. It is designed to be pressed into a hole in a deck plate, allowing a flat, smooth object like a tray to be moved and rotated in any direction by hand. The unit weighs 768 g and is available with a steel, galvanized steel, chrome plated steel or stainless steel case.
Part of the KS KSM Series range, used in Warehouse and Distribution Centres.
Key Benefits
- Carries 100 kg per unit in normal service and 150 kg at peak load
- Spring loaded design maintains ball contact under load and compensates for minor deck misalignment
- Press mount fixes the unit into a hole in the deck plate for a flush, stable installation
- 30 mm diameter ball allows smooth movement of trays and flat components across a deck
- Steel or stainless steel case options suit dry, wet or washdown environments
Application Scenarios
- Transfer points in a flat conveyor line where trays need to be rotated or repositioned by hand
- Feeding stations on a packaging line where a tray must be turned to align with the next process
- Assembly line workstations where a component is rotated between operations
- Processing machinery where a flat part is moved across a table in multiple directions
- Curved work surfaces on band saws or router tables requiring omnidirectional movement
Who It Is For
- Conveyor system integrators building transfer and rotation points into a line
- Material handling equipment builders designing decks for tray handling
- Packaging machinery manufacturers needing omnidirectional movement in feeding systems
- Industrial distributors stocking ball transfer units by load and mounting type
Problems It Solves
- Trays or flat parts that stick or jam when pushed across a fixed deck plate
- Transfer points where product must change direction without powered diverters
- Operators struggling to rotate a load by hand due to high friction or misaligned rollers
- Decks with uneven surfaces where a fixed ball transfer unit loses contact
- Need for a compact, flush-mounted unit that does not interfere with product movement
Technical Features
- Spring loaded mechanism maintains ball contact under load
- 30 mm diameter steel ball for consistent rolling performance
- Press mount design with a 49 mm mounting diameter for secure fit
- Housing made from carbon steel, galvanized steel, chrome plated steel or stainless steel
- Unit weight of 768 g for deck load and shipping calculations
Materials
- Carbon steel case for general industrial use
- Galvanized steel case for mild corrosion resistance
- Chrome plated steel case for improved wear and appearance
- Stainless steel (SUS304) case for wet, washdown or corrosive environments
Quality Control
- Load capacity verified against the 100 kg working load rating
- Ball rotation checked by hand for free movement in all directions
- Material grade confirmed against the case option ordered
Customization Options
- Case material selected between carbon steel, galvanized steel, chrome plated steel and stainless steel
- Other KSF Series load ratings available where 100 kg is not the right size
- Spring load adjustment not available, but unit is designed for standard load conditions
Use Guide
- Divide the load by the number of units in contact to check the 100 kg per unit rating
- Keep peak and impact loading below the 150 kg maximum load figure
- Press the unit into a hole with a 49 mm diameter to ensure a secure fit
- Use only on flat, smooth surfaces such as trays or sheet metal
- Avoid use on soft or uneven bottom surfaces like cloth-wrapped items

Compared With Other Options
| Flange mount ball transfer units | Press mount units are flush with the deck and require no bolts, while flange mount units are easier to remove and replace |
|---|---|
| Lower rated KSF Series units | The KSF-30 suits 100 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 |
