Part of the IK UK Series range, used in Warehouse and Distribution Centres.
Key Benefits
- Carries 8 kg per unit in normal service and 15 kg at peak load
- Downward mount fixes the unit from below, allowing a flush deck surface
- Two screw holes in the case provide solid attachment to worktables and benches
- Steel ball and case options suit dry, general industrial environments
- Stainless steel (SUS304) case option for wet or corrosive areas
Application Scenarios
- Transfer points on a flat deck where trays or rigid containers need to be moved in any direction
- Feeding systems in packaging machinery where product alignment is required
- Processing tables where flat components are rotated or repositioned by hand
- Assembly line stations where a fixture must be turned without powered guidance
- Curved work surfaces on router tables or band saws where omnidirectional movement is needed
Who It Is For
- Conveyor system integrators building low-load transfer zones
- Material handling equipment builders designing worktables and feed points
- Packaging machinery manufacturers needing omnidirectional movement
- Industrial distributors stocking ball transfer units by load and mounting type
- Production line builders requiring downward-mounted units for compact design
Problems It Solves
- Flat items that jam when pushed across a fixed deck due to lack of omnidirectional motion
- Worktables where product must be repositioned by hand without powered diverters
- Systems where a flush deck surface is required and upward-mounted units interfere
- Applications needing a low-profile transfer point with secure mounting
- Transfer zones where multiple units must be aligned on a single deck without height variation
Technical Features
- 12.7 mm diameter steel ball for consistent rolling under low load
- Downward mount with 35 mm diameter hole and two screw holes for secure attachment
- Omnidirectional ball bearing allows movement in any direction on a flat surface
- Case made from carbon steel, galvanized steel, chrome plated steel or stainless steel (SUS304)
- Unit weight of 180 g for deck load and shipping calculations
Materials
- Carbon steel ball and case for general industrial use
- Galvanized steel case for improved corrosion resistance in moderate environments
- Chrome plated steel case for a smoother surface and better wear resistance
- Stainless steel (SUS304) case for wet, washdown or corrosive areas
Quality Control
- Load capacity verified against the 8 kg working load before packing
- Ball rotation checked by hand for free movement in all directions
- Material grade confirmed against the case and ball option ordered
- Mounting holes checked for correct diameter and alignment
Customization Options
- Case material selected between carbon steel, galvanized steel, chrome plated steel and stainless steel (SUS304)
- Ball material is steel, not available in nylon or stainless steel
- Other UK Series load ratings available where 8 kg is not the right size
Use Guide
- Divide the load by the number of units in contact to ensure the 8 kg per unit rating is not exceeded
- Keep peak and impact loading below the 15 kg maximum load figure
- Mount units on a flat deck plate so all balls sit at the same height
- Use only on flat, smooth surfaces such as trays or rigid components
- Avoid use on soft or uneven bottom surfaces like cloth-wrapped items

Compared With Other Options
| Upward ball transfer units | Downward mount allows a flush deck surface and is better for worktables with limited height clearance |
|---|---|
| Press fit ball transfer units | Downward mount uses screws for secure attachment, while press fit units are faster to install but harder to remove |
| Higher load rated units | The UK-12 is suited for 8 kg loads, so heavier applications require a larger unit with higher capacity |
Downward Ball Transfer Unit UK-12 Questions
What load can one UK-12 ball transfer unit carry?
The rated load capacity is 8 kg per unit and the maximum load capacity is 15 kg.
How is the UK-12 mounted?
It is a downward mount unit, so it is secured from below through a 35 mm diameter hole with two screws.
Which case material should I choose?
Carbon steel for general use, galvanized steel for better corrosion resistance, chrome plated steel for wear resistance, or stainless steel (SUS304) for wet or corrosive environments.
Is a stainless steel version available?
Yes, the case can be supplied in stainless steel (SUS304).
How much does the unit weigh?
Each UK-12 weighs 180 g, which is used for deck load and shipping calculations.
Can I get other load ratings in the same series?
Yes, the UK Series includes other load ratings, so ask for the model that matches your load per unit.
