- Nylon ball option protects painted or polished surfaces from marking
- Stainless steel ball and case option for wet or washdown environments
Application Scenarios
- Transfer points between two conveyor lines where product must be rotated or repositioned by hand
- Feeding tables in packaging or processing machinery where trays are moved in multiple directions
- Assembly stations requiring manual reorientation of flat components
- Workbenches with curved or angled surfaces where omnidirectional movement is needed
- Conveyor decks where a consistent load rating is required across multiple transfer points
Who It Is For
- Conveyor system integrators building transfer and rotation points into material handling lines
- Industrial equipment builders designing feeding and processing tables
- Packaging machinery manufacturers needing omnidirectional movement for trays
- Material handling equipment makers integrating ball transfer units into custom decks
- Industrial distributors stocking ball transfer units by load rating and mounting type
Problems It Solves
- Loads that jam or bind when pushed across a fixed deck plate or plain rollers
- Transfer points where product must change direction without powered diverters
- Operators struggling to reposition flat items by hand at the end of a line
- Mixed-duty decks where a single load rating must support both light and heavy items
- Mounting systems that require secure attachment without press fitting or welding
Technical Features
- 22 mm diameter ball with fine machined seat for consistent rolling under load
- Screw mount with two M44 diameter holes for secure attachment to deck plates
- Main ball available in nylon, steel or stainless steel to match surface requirements
- Case available in steel or stainless steel for dry or wet environments
- Unit weight of 280 g for deck load and shipping calculations
Materials
- Nylon main ball for non marking contact with painted or polished surfaces
- Carbon steel ball and case for general industrial decks
- Stainless steel ball and case for wet, washdown or corrosive areas
Quality Control
- Load capacity checked against the 40 kg rating before packing
- Ball rotation checked by hand for free movement in all directions
- Material grade confirmed against the ball and case option ordered
Customization Options
- Ball material selected between nylon, steel and stainless steel
- Case material selected between steel and stainless steel
- Other LW Series load ratings available where 40 kg is not the right size
Use Guide
- Divide the load by the number of units in contact to check the 40 kg per unit rating
- Keep peak and impact loading below the 45 kg maximum load figure
- Mount units on a flat 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 washed down

Compared With Other Options
| Press mount ball transfer units | Screw mount allows secure attachment and easy removal for service, while a press fit unit is faster to install but harder to replace |
|---|---|
| Lower rated LW Series units | The LW-22 suits 40 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 |
