Part of the KS KSM Series range, used in Warehouse and Distribution Centres.
Key Benefits
- Carries 120 kg per unit in normal service and 150 kg at peak load
- Pipe mount fits directly onto a 25.4 mm diameter tube or pipe for quick installation
- Steel ball provides consistent rolling performance under heavy static and dynamic loads
- Available in galvanized, chrome-plated or stainless steel cases for different environmental needs
- Two screw holes in the housing allow secure attachment to a workbench or frame
Application Scenarios
- Transfer points between two conveyor lines where product must rotate freely in any direction
- Feeding systems in packaging machinery where trays or flat parts need omnidirectional movement
- Processing tables on CNC routers or band saws where workpieces are repositioned by hand
- Assembly line workstations where a fixture or component is turned or aligned without powered movement
- Material handling decks where a flat load must be moved across a fixed pipe-mounted support
Who It Is For
- Conveyor system integrators building transfer points with pipe-mounted components
- Industrial equipment builders designing worktables with manual repositioning
- Packaging machinery manufacturers needing reliable omnidirectional movement
- Production line builders integrating manual rotation points into assembly stations
- Industrial distributors stocking pipe mount ball transfer units by load and mounting size
Problems It Solves
- Flat loads that stick or drag when pushed across a fixed pipe or tube
- Transfer points where product must change direction without powered diverters
- Worktables where a heavy or rigid component must be rotated by hand without resistance
- Systems requiring a consistent mounting method across multiple units on a single pipe
- Applications where a single load rating must support both steady and impact loading
Technical Features
- 25.4 mm diameter steel ball for consistent rolling and load distribution
- Pipe mount design with a 25.4 mm inner diameter to fit standard tubing
- Steel ball and case with options for galvanized, chrome-plated or stainless steel finishes
- Two threaded holes in the housing for secure mounting to a workbench or frame
- Compact size of 37 mm diameter by 22.5 mm height for tight space applications
Materials
- Carbon steel ball and case for general industrial use
- Galvanized steel case for improved corrosion resistance in damp environments
- Chrome-plated steel case for wear resistance and a clean appearance
- Stainless steel (SUS304) case and steel ball for washdown, food, or corrosive areas
Quality Control
- Load capacity verified against the 120 kg working load rating
- Ball rotation checked by hand for free movement in all directions
- Mount diameter confirmed to be 25.4 mm to fit standard tubing
- Material grade confirmed against the case finish option ordered
Customization Options
- Case material selected between carbon steel, galvanized steel, chrome-plated steel and stainless steel (SUS304)
- Ball material is steel, not available in nylon or other materials
- Other KSM Series load ratings available where 120 kg is not the right size
Use Guide
- Ensure the pipe or tube diameter is exactly 25.4 mm for a secure fit
- Divide the total load by the number of units in contact to stay under the 120 kg per unit rating
- Keep peak and impact loading below the 150 kg maximum load figure
- Use stainless steel case and ball where the unit is exposed to washdown or corrosive environments
- Avoid using on uneven or soft-bottomed items such as cloth-wrapped loads

Manufacturing Process
Step 1
Machining of the case and mounting bore to fit 25.4 mm pipe
Step 2
Assembly of the steel ball and support bearings into the case
Step 3
Drilling and tapping of two mounting holes in the housing
Step 4
Final inspection of ball rotation and mounting fit
Step 5
Packing for shipping and storage
Compared With Other Options
| Flange mount ball transfer units | Pipe mount fits directly onto a tube, while flange mount requires a deck plate and bolt-through mounting |
|---|---|
| Press fit ball transfer units | Pipe mount allows easy removal and replacement, while press fit units are fixed in place and harder to service |
| Lower rated KSM Series units | The KSM-25 suits 120 kg loads, so lighter applications are better served by a smaller unit with less rolling resistance |
Pipe Mount Ball Transfer Unit KSM-25 Questions
What load can one KSM-25 ball transfer unit carry?
The rated load capacity is 120 kg per unit and the maximum load capacity is 150 kg.
How is the KSM-25 mounted?
It is a pipe mount unit, so it fits directly onto a 25.4 mm diameter tube or pipe.
Which case material should I choose?
Carbon steel for general use, galvanized for damp areas, chrome-plated for wear resistance, stainless steel (SUS304) for washdown or corrosive environments.
Is a stainless steel version available?
Yes, the case can be supplied in stainless steel (SUS304) with a steel ball.
How much does the unit weigh?
Each KSM-25 weighs 250 g, which is used for deck load and shipping calculations.
Can I get other load ratings in the same series?
Yes, the KSM Series includes other load ratings, so ask for the model that matches your load per unit.
