Key Benefits
- Carries 25 kg per unit in normal service and 30 kg at peak load
- Screw mount with two holes allows firm attachment to a worktable or deck
- 19.05 mm diameter ball provides stable support for flat, smooth objects
- Nylon ball option protects painted or polished surfaces from marking
- Stainless steel ball and case option for wet or washdown environments
Application Scenarios
- Conveyor transfer points where flat trays or components need to be rotated by hand
- Assembly line feeding stations requiring 360-degree movement of parts
- Packaging machinery where trays are repositioned between stations
- Processing tables where a flat component must be aligned in any direction
- Feeding systems in machining or cutting equipment where precise positioning is needed
Who It Is For
- Conveyor system integrators building transfer points with manual repositioning
- Industrial equipment builders requiring reliable ball transfer units for worktables
- Assembly line designers needing omnidirectional movement for tray handling
- Material handling equipment makers integrating ball transfer units into processing lines
- Industrial distributors stocking ball transfer units by load and mounting type
Problems It Solves
- Flat trays or components that jam when pushed across a fixed deck due to lack of omnidirectional movement
- Transfer points where product must be rotated or repositioned without powered guidance
- Worktables where components must be aligned in multiple directions by hand
- Systems requiring a fixed mounting method that allows secure attachment and future maintenance
- Applications where surface marking from steel balls must be avoided on painted or polished decks
Technical Features
- 19.05 mm diameter ball allows consistent contact with flat, smooth surfaces
- Screw mount with two M40 holes provides a stable and removable attachment
- Main ball supplied in nylon, steel or stainless steel to match surface requirements
- Case supplied in steel or stainless steel for durability in dry or wet environments
- Unit weight of 160 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 use
- Stainless steel ball and case (SUS304) for wet, washdown or corrosive areas
Quality Control
- Load capacity checked against the 25 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 models in the LW series available where 25 kg is not the right size
Use Guide
- Divide the load by the number of units in contact to ensure no more than 25 kg per unit
- Keep peak and impact loading below the 30 kg maximum load figure
- Mount units 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 washdown or moisture

Compared With Other Options
| Press mount ball transfer units | Screw mount allows secure attachment and easier removal for maintenance, while a press fit unit is faster to install but harder to replace |
|---|---|
| Lower rated LW Series units | The LW-19 suits 25 kg loads, so lighter applications are better served by a smaller unit with lower rolling resistance |
| Plain conveyor rollers | Ball transfer units allow movement in any direction, while rollers only move product along one axis |
