Downward Ball Transfer Unit UK-30T
The UK-30T is a downward ball transfer unit with a 30.16 mm diameter steel ball, rated for 150 kg working load and 200 kg maximum load. It mounts through a 95 mm diameter hole from below the deck plate, allowing a flat, smooth object like a tray to be moved in any direction by hand. The unit weighs 3.2 kg and is available with a steel, galvanized steel, chrome-plated steel, or stainless steel case and a steel main ball.
Product Overview
The UK-30T is a downward ball transfer unit with a 30.16 mm diameter steel ball, rated for 150 kg working load and 200 kg maximum load. It mounts through a 95 mm diameter hole from below the deck plate, allowing a flat, smooth object like a tray to be moved in any direction by hand. The unit weighs 3.2 kg and is available with a steel, galvanized steel, chrome-plated steel, or stainless steel case and a steel main ball.
Part of the IK UK Series range, used in Warehouse and Distribution Centres.
Key Benefits
- Carries 150 kg per unit in normal service and 200 kg at peak load
- Downward mount fixes the unit from below, allowing full access to the deck surface
- Steel ball and case provide durability in industrial handling environments
- 30.16 mm ball diameter allows smooth movement of flat trays and rigid components
- Two screw holes in the housing allow secure attachment to the worktable or bench
Application Scenarios
- Transfer points in a conveyor line where trays or rigid components need to be repositioned by hand
- Feeding systems on machining or packaging lines where a flat item must be rotated or shifted
- Processing machinery where a tray is moved across a workbench for assembly or inspection
- Curved work areas on band saws or router tables requiring omnidirectional movement
- Assembly lines where a fixture or tool is manually aligned at a workstation
Who It Is For
- Conveyor system integrators building manual transfer and alignment points
- Industrial equipment builders designing workbenches with movable trays
- Packaging machinery manufacturers integrating transfer zones into feed systems
- Assembly line designers needing manual repositioning without powered diverters
- Material handling equipment makers sourcing downward-mounted ball transfer units
Problems It Solves
- Manual repositioning of flat trays or components that cannot be moved by rollers alone
- Transfer points where product must change direction without a powered mechanism
- Workbenches where access to the deck surface must remain unobstructed by mounting hardware
- Systems requiring a stable, fixed mounting point for a ball transfer unit without protruding fasteners
- Applications where a downward mount avoids interference with adjacent equipment or conveyors
Technical Features
- Downward mount with 95 mm diameter hole for installation from below the deck
- 30.16 mm diameter steel ball for consistent rolling under load
- Steel case with optional galvanizing, chrome plating, or stainless steel finish
- Two threaded holes in the housing for secure attachment to the worktable
- Overall dimensions of 117 mm diameter and 64 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 smooth finish
- Stainless steel case (SUS304) for washdown, food, or chemical exposure areas
Quality Control
- Load capacity verified against the 150 kg working load rating
- Ball rotation checked by hand for free movement in all directions
- Material grade confirmed against the case finish option ordered
- Mounting hole diameter checked to ensure 95 mm compatibility
Customization Options
- Case finish selected between steel, galvanized steel, chrome-plated steel, or stainless steel
- Ball material is fixed as steel in this model
- Other models in the UK Series available for different load ratings or mounting types
Use Guide
- Ensure the deck plate has a 95 mm clearance hole for downward mounting
- Divide the total load by the number of units in contact to stay within the 150 kg per unit rating
- Keep peak and impact loading below the 200 kg maximum load figure
- Use stainless steel case where the unit is exposed to washdown or corrosive environments
- Avoid using on soft or uneven surfaces such as cloth-wrapped items or flexible packaging

Manufacturing Process
Step 1
Machining of the case and mounting flange
Step 2

Compared With Other Options
| Upward ball transfer units | Downward mount installs from below the deck, leaving the surface unobstructed, while upward units mount from above and may interfere with adjacent components |
|---|---|
| Press fit ball transfer units | Downward mount uses screws for secure attachment, while press fit units rely on friction and may loosen over time |
| Smaller UK Series units | The UK-30T suits 150 kg loads, so lighter applications may be better served by a smaller unit with less rolling resistance |
