Part of the NJ LW FB Series range, used in Sheet Metal and Press Shops.
Key Benefits
- 150 kg working load and 200 kg maximum load per unit for heavy-duty handling
- Stud mount with M14 diameter allows secure, bolted attachment to a deck or table
- Hexagon case design provides stable mounting and resistance to rotation under load
- Nylon ball option protects painted or polished surfaces from marking
- Stainless steel ball and case option suitable for wet, washdown or corrosive environments
Application Scenarios
- Transfer points on a flat deck where trays or panels need to be moved in any direction
- Assembly lines with fixed workstations requiring manual repositioning of components
- Feeding systems for packaging machinery where flat items must be aligned or rotated
- Processing tables for CNC routers or band saws where workpieces are adjusted by hand
- Conveyor integration points where a load must be transferred between two lines at an angle
Who It Is For
- Conveyor system integrators building transfer and alignment points into a line
- Industrial equipment builders designing worktables with manual load positioning
- Packaging machinery manufacturers requiring omnidirectional movement of flat items
- Material handling equipment makers building fixed deck transfer systems
- Industrial distributors stocking ball transfer units by load rating and mounting type
Problems It Solves
- Loads that cannot be rotated or repositioned easily on a fixed deck surface
- Transfer points where product must change direction without powered diverters
- Workstations where operators need to manually align or turn a heavy panel or tray
- Fixed decks where a single unit must handle both light and heavy items without jamming
- Mounting systems that require a secure, bolted attachment instead of a press fit
Technical Features
- 30.16 mm diameter ball with fine machined seat for consistent rolling under load
- Stud mount with M14 diameter for secure, bolted attachment to a deck plate
- Hexagon case shape prevents rotation and provides stable mounting
- Ball and case materials selected independently to suit environment and surface contact
- Unit weight of 230 g for deck load and shipping calculations
Materials
- Nylon ball for non-marking contact with painted or polished surfaces
- Carbon steel ball and case for general industrial use in dry environments
- Stainless steel ball and case (SUS304) for wet, washdown or corrosive areas
Quality Control
- Load capacity verified against the 150 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
- Stud diameter and threading inspected for correct M14 fit
Customization Options
- Ball material selected between nylon, steel and stainless steel
- Case material selected between steel and stainless steel
- Other NJ Series load ratings available where 150 kg is not the right size
Use Guide
- Divide the total load by the number of units in contact to ensure no unit exceeds 150 kg working load
- Keep peak and impact loading below the 200 kg maximum load figure
- Mount the unit on a flat, rigid deck plate so all balls sit at the same height
- Choose the nylon ball where the load surface must not be marked
- Choose stainless steel ball and case where the deck is exposed to moisture or cleaning agents

Manufacturing Process
Step 1
Machining of the hexagon case and stud mounting hole

Assembly of ball and support bearings into the case
Step 4
Stud threading and finishing for secure bolt attachment
Step 5
Load test and visual inspection before packing
Compared With Other Options
| Flange mount ball transfer units | Stud mount bolts through the deck and allows easier removal, while a flange mount is fixed from above and may require deck plate modification |
|---|---|
| Press fit ball transfer units | Stud mount provides a secure, bolted connection that can be serviced or replaced, while a press fit is faster to install but harder to remove |
| Lower rated NJ Series units | The NJ-30 suits 150 kg loads, so lighter applications are better served by a smaller unit that rolls with less effort |
