Key Benefits
- 300 kg working load and 350 kg maximum load per unit
- Downward mount with two screw holes for secure attachment to a deck
- 52 mm diameter steel ball allows smooth 360-degree rotation
- Available in carbon steel, galvanized steel, chrome-plated steel, or stainless steel (SUS304) case
- Suitable for flat, smooth surfaces such as trays and sheet metal
Application Scenarios
- Feeding systems where trays or flat components need to be rotated or repositioned at a workstation
- Processing machinery with curved work surfaces such as router tables or band saws
- Packaging lines where product orientation must be adjusted without powered diverters
- Assembly stations requiring manual repositioning of flat parts on a workbench
- Conveyor transfer points where a load must be moved in any direction across a fixed deck
Who It Is For
- Conveyor system integrators building feeding and transfer points
- Industrial equipment builders designing workstations with adjustable positioning
- Packaging machinery manufacturers needing omnidirectional movement
- Assembly line builders requiring manual repositioning of flat components
- Material handling equipment makers sourcing high-load ball transfer units
Problems It Solves
- Heavy flat loads that cannot be rotated or repositioned by hand on a fixed deck
- Transfer points where product must change direction without powered mechanisms
- Workstations where a tray or component must be turned or aligned manually
- Systems requiring a stable, non-tilting transfer point for flat items
- Need for a single component that replaces multiple rollers or casters
Technical Features
- 52 mm diameter steel ball for high load capacity and durability
- Downward mount with two screw holes for secure attachment to a deck
- Housing made from carbon steel, galvanized steel, chrome-plated steel, or stainless steel (SUS304)
- Omnidirectional ball movement within a restraining fixture
- Unit weight of 5.5 kg for deck load and shipping planning
Materials
- Carbon steel case for general industrial use
- Galvanized steel case for improved corrosion resistance in humid environments
- Chrome-plated steel case for wear resistance and a smoother surface
- Stainless steel (SUS304) case for washdown, food, or chemical exposure
Quality Control
- Load capacity verified against the 300 kg working load rating
- Ball rotation checked by hand for free movement in all directions
- Material grade confirmed against the case option ordered
Customization Options
- Case material selected between carbon steel, galvanized steel, chrome-plated steel, and stainless steel (SUS304)
- Ball material is steel and not available in nylon or other materials
- Other UK Series models available for different load ratings
Use Guide
- Ensure the load is distributed evenly across the ball to avoid exceeding 300 kg per unit
- Keep peak and impact loads below the 350 kg maximum load capacity
- Mount the unit on a flat, rigid deck so the ball sits at the correct height
- Use stainless steel case where exposure to water, cleaning agents, or corrosive environments is expected
- Do not use on uneven or soft-bottomed items such as cloth-wrapped loads

Compared With Other Options
| Upward ball transfer units | Downward mount fixes the unit from below, allowing the deck to remain flat, while upward units are mounted from above and may interfere with load height |
|---|---|
| Standard roller bearings | Ball transfer units allow omnidirectional movement, while roller bearings only move in one direction |
| Casters or swivel wheels | Downward ball transfer units are fixed to a deck and do not roll on the floor, making them suitable for stationary workstations |
