Part of the IK UK Series range, used in Warehouse and Distribution Centres.
Key Benefits
- 100 kg working load and 120 kg maximum load per unit for medium-duty handling
- Downward mount fixes the unit from below, allowing the deck plate to remain flat and unobstructed
- Two screw holes in the case provide strong attachment to worktables or conveyor decks
- Steel ball and case options suit industrial environments with general wear and tear
- Stainless steel (SUS304) version available for wet or corrosive conditions
Application Scenarios
- Transfer points on a flat deck where trays or flat panels need to be repositioned in any direction
- Feeding systems in packaging machinery where flat items must be aligned or rotated
- Processing tables on band saws or router tables requiring 360-degree movement of workpieces
- Assembly line stations where a fixture or component is manually reoriented between operations
- Conveyor deck sections where a change in direction is needed without powered diverters
Who It Is For
- Conveyor system integrators building medium-load transfer zones
- Industrial equipment builders designing worktables with movable platforms
- Packaging machinery manufacturers needing omnidirectional load transfer
- Assembly line designers requiring manual repositioning points
- Material handling equipment makers sourcing consistent ball transfer units by load
Problems It Solves
- Flat objects that jam or drag when pushed across a fixed deck due to lack of omnidirectional movement
- Transfer points where product must change direction without a powered mechanism
- Worktables where a load must be rotated or aligned by hand without slipping
- Systems requiring a low-profile, downward-mounted unit that does not interfere with deck height
- Sourcing a single unit that matches a specific tube diameter and shaft size without mixing suppliers
Technical Features
- 25.4 mm diameter steel ball for consistent rolling under medium load
- Downward mount with 45 mm diameter mounting hole and two screw holes for secure attachment
- Steel ball and case with options in carbon steel, galvanized steel, chrome plated steel or stainless steel (SUS304)
- Compact dimensions of 57 mm diameter and 42 mm height for tight deck spacing
- Weight of 460 g for deck load and shipping 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 enhanced wear resistance and appearance
- Stainless steel (SUS304) case with steel ball for wet, washdown or food-grade areas
Quality Control
- Load capacity verified against the 100 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
Customization Options
- Case material selected between carbon steel, galvanized steel, chrome plated steel or stainless steel (SUS304)
- Ball material is steel, not available in nylon or other materials
- Other UK Series load ratings available where 100 kg is not the right size
Use Guide
- Divide the total load by the number of units in contact to ensure no unit exceeds 100 kg working load
- Keep peak or impact loading below the 120 kg maximum load rating
- Mount the unit in a flat deck plate so the ball sits level with adjacent units
- Use stainless steel version in wet or washdown environments
- Do not use on uneven or soft-bottomed items such as cloth-wrapped loads

Compared With Other Options
| Flange mount ball transfer units | Downward mount is installed from below, leaving the deck surface flat, while flange mount units project above the deck |
|---|---|
| Higher rated UK Series units | The UK-25 suits 100 kg loads, so heavier applications require a larger unit in the same series |
| Press fit ball transfer units | Downward mount uses screws for secure attachment, while press fit units are faster to install but harder to replace |
