Pipe Mount Ball Transfer Unit KSM-12
The KSM-12 is a pipe mount ball transfer unit with a 12 mm steel ball, rated for 25 kg working load and 30 kg maximum load. It mounts onto a 22 mm diameter pipe using two screw holes in the housing, allowing a flat, smooth object like a tray to be moved and rotated in any direction by hand. The unit weighs 35 g and is available with a carbon steel or stainless steel case and a steel ball.

Part of the KS KSM Series range, used in Warehouse and Distribution Centres.
Key Benefits
- Carries 25 kg per unit in normal service and 30 kg at peak load
- Pipe mount fits over a 22 mm diameter pipe with two screw holes for secure attachment
- 12 mm steel ball provides consistent rolling motion under light to moderate load
- Carbon steel case for general industrial use and stainless steel case for wet or corrosive environments
- Low weight of 35 g reduces deck load and shipping cost
Application Scenarios
- Transfer points on a conveyor line where trays need to be rotated or repositioned by hand
- Feeding systems in packaging machinery where flat items are moved between stations
- Processing tables where a tray is turned or aligned during assembly or inspection
- Curved work surfaces on band saws or router tables requiring omnidirectional movement
- Auxiliary equipment on production lines where a light load must be shifted without powered drive
Who It Is For
- Conveyor system integrators building low-load transfer points into a line
- Packaging machinery builders needing omnidirectional movement for trays
- Industrial equipment makers integrating ball transfer units into worktables
- Production line designers requiring a compact, low-weight transfer solution
- Industrial distributors stocking ball transfer units by load and mounting type
Problems It Solves
- Trays or flat items that jam when pushed across a fixed or unidirectional surface
- Transfer points where product must change direction without a powered diverter
- Light loads that are difficult to rotate or align by hand on a rigid deck
- Need for a compact, low-weight unit that fits onto a standard 22 mm pipe
- Requirement for a ball transfer unit that can be securely fastened with screws
Technical Features
- 12 mm steel ball provides consistent rolling motion in all directions
- Pipe mount design fits over a 22 mm diameter pipe with two screw holes
- Housing made from carbon steel, galvanized steel, chrome plated steel, or stainless steel
- Steel ball ensures durability under repeated light load cycles
- Compact dimensions of 22 mm diameter by 17 mm height for tight space applications
Materials
- Carbon steel case for general industrial environments
- Galvanized steel case for improved corrosion resistance in damp areas
- Chrome plated steel case for a smoother surface and better wear resistance
- Stainless steel (SUS304) case for wet, washdown or corrosive environments
- Steel ball for consistent rolling under light to moderate load
Quality Control
- Load capacity verified against the 25 kg working load before packing
- Ball rotation checked by hand for free movement in all directions
- Material grade confirmed against the case and ball option ordered
- Mounting holes inspected for correct alignment and thread integrity
- Unit weight verified at 35 g for shipping and deck load calculations
Customization Options
- Case material selected between carbon steel, galvanized steel, chrome plated steel, and stainless steel (SUS304)
- Ball material fixed as steel in this model, no alternative ball material available
- Other KSM Series models available for different load ratings or mounting types
Use Guide
- Ensure the pipe diameter is 22 mm to match the unit's mounting size
- Divide the total load by the number of units in contact to stay within the 25 kg per unit rating
- Keep peak and impact loading below the 30 kg maximum load figure
- Use only on flat, smooth surfaces such as trays or metal sheets
- Avoid using on uneven, soft, or flexible surfaces like cloth-wrapped items

Compared With Other Options
| Flange mount ball transfer units | Pipe mount fits over a 22 mm pipe and is secured with screws, while a flange mount bolts from above and requires a deck plate |
|---|---|
| Press fit ball transfer units | Pipe mount allows removal and replacement without damaging the pipe, while a press fit unit is harder to service |
| Higher load rated units | The KSM-12 suits 25 kg loads, so heavier applications require a larger model with higher capacity |
