Part of the IK UK Series range, used in Warehouse and Distribution Centres.
Key Benefits
- 200 kg working load and 250 kg maximum load for heavy flat material handling
- Downward mount with 120 mm diameter base allows secure attachment to worktables
- 38.1 mm steel ball provides stable rolling under heavy static and dynamic loads
- Steel, galvanized steel, chrome-plated steel or stainless steel case options for different environments
- Two screw holes in the base allow firm attachment to a flat deck or bench
Application Scenarios
- Transfer points on a curved conveyor deck where trays must be rotated between sections
- Assembly line workstations where heavy flat components are repositioned by hand
- Packaging machinery feed zones requiring omnidirectional movement of rigid trays
- Processing tables where a flat part must be aligned and turned without powered guidance
- Feeding systems in manufacturing where a flat load needs to be shifted in any direction
Who It Is For
- Conveyor system integrators building downward transfer points into a line
- Industrial equipment builders designing worktables with manual rotation capability
- Assembly line designers needing manual repositioning of heavy flat parts
- Packaging machine manufacturers requiring omnidirectional tray handling
- Material handling equipment makers sourcing high-load ball transfer units
Problems It Solves
- Heavy flat loads that cannot be rotated or shifted manually on a fixed deck
- Transfer points where product must change direction without powered diverters
- Worktables where a large flat part must be turned or aligned by hand under load
- Systems requiring a single unit to handle multiple movement directions without repositioning
- Mounting issues where a press-fit unit is not secure enough for high-load applications
Technical Features
- 38.1 mm diameter steel ball for consistent rolling under heavy load
- Downward mount with 120 mm diameter base for stable attachment to worktables
- Steel case with optional galvanizing, chrome plating or stainless steel for corrosion resistance
- Two screw holes in the base for secure fastening to a flat surface
- Overall dimensions of 148 mm diameter by 81 mm height for deck space planning
Materials
- Carbon steel ball and 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 case (SUS304) for washdown, food, or corrosive environments
Quality Control
- Load capacity verified against the 200 kg working load rating
- Ball rotation checked by hand for free movement in all directions
- Mounting diameter and base flatness confirmed to match the 120 mm specification
- Material grade confirmed against the case option ordered
Customization Options
- Case material selected between carbon steel, galvanized steel, chrome-plated steel and stainless steel
- Ball material is steel, but other materials are not available in this model
- Other UK Series models available for different load ratings or mounting styles
Use Guide
- Ensure the deck plate is flat and level so all balls sit at the same height
- Divide the total load by the number of units in contact to stay within the 200 kg per unit rating
- Keep peak and impact loads below the 250 kg maximum load limit
- Use stainless steel case in washdown or corrosive environments
- Avoid using on uneven or soft-bottomed items like cloth-wrapped goods

Compared With Other Options
| Upward ball transfer units | Downward mount fixes the unit from below, allowing a flush deck surface, while upward units are mounted from above and may interfere with load height |
|---|---|
| Press-fit ball transfer units | Downward mount with screw holes allows secure attachment and easier replacement, while press-fit units are faster to install but harder to service |
| Lower load UK Series units | The UK-38T suits 200 kg loads, so lighter applications are better served by smaller units that roll with less effort |
