Downward Ball Transfer Unit IK-51N
The IK-51N is a downward ball transfer unit with a 51 mm diameter steel ball, rated for 400 kg working load and 450 kg maximum load. It mounts through a downward flange with M24 diameter mounting holes onto a deck plate or workbench, allowing heavy flat items like trays to be moved and rotated in any direction by hand. The unit weighs 4.4 kg and is available with a steel, galvanized steel, chrome-plated steel or stainless steel case.
Product Overview

Part of the IK UK Series range, used in Warehouse and Distribution Centres.
Key Benefits
- Carries 400 kg per unit in normal service and 450 kg at peak load
- Downward mount with M24 diameter holes allows secure attachment from below
- 51 mm diameter steel ball provides stable, smooth omnidirectional movement
- Steel, galvanized steel, chrome-plated steel or stainless steel case options for different environments
- Two screw holes around the bearing allow solid attachment to worktables and benches
Application Scenarios
- Downward transfer points on a conveyor line where heavy trays must be rotated or repositioned
- Workbenches in assembly or packaging lines requiring manual reorientation of flat components
- Processing machinery where a flat part needs to be moved freely in any direction
- Feeding systems for automated lines where a tray must be aligned or turned by hand
- Curved work surfaces on band saws or router tables where omnidirectional movement is needed
Who It Is For
- Conveyor system integrators building downward transfer points into production lines
- Assembly line builders needing manual repositioning of heavy flat parts
- Packaging machinery manufacturers integrating transfer units into feeding systems
- Industrial equipment makers designing workbenches with manual load rotation
- Material handling equipment builders sourcing high-load ball transfer units in volume
Problems It Solves
- Heavy flat loads that cannot be rotated or repositioned easily on a fixed deck
- Transfer points where product must change direction without powered diverters
- Workbenches where a heavy tray or fixture must be turned by hand without resistance
- Systems requiring consistent load capacity across multiple transfer points
- Mounting issues where a standard flange or press-fit unit does not provide secure attachment
Technical Features
- 51 mm diameter steel ball for high load and stable omnidirectional motion
- Downward mount with M24 diameter mounting holes for attachment from below
- Two screw holes around the bearing for secure fixation to worktables
- Steel case with options for galvanization, chrome plating or stainless steel finish
- 5.71 inch height and 3.94 inch diameter for integration into standard deck layouts
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 appearance
- Stainless steel case (SUS304) for washdown, food, or corrosive environments
Quality Control
- Load capacity verified against the 400 kg working load rating
- 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 M24 diameter and alignment
Customization Options
- Case material selected between steel, galvanized steel, chrome-plated steel and stainless steel
- Ball material is steel, as specified in the standard configuration
- Other models in the IK UK Series available for different load ratings or mounting styles
Use Guide
- Divide the total load by the number of units in contact to ensure each unit stays under 400 kg
- Keep peak and impact loading below the 450 kg maximum load limit
- Mount the unit on a flat, rigid deck plate so the ball sits level and rotates freely
- Use stainless steel case where the unit is exposed to washdown or corrosive conditions
- Avoid using on soft or uneven surfaces such as cloth-wrapped items or flexible packaging

Load check and packing
Compared With Other Options
| Upward ball transfer units | Downward mount allows attachment from below, while upward units are mounted from above and require a recessed deck |
|---|---|
| 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 rated units | The IK-51N suits 400 kg loads, so lighter applications are better served by smaller units with less resistance |
Downward Ball Transfer Unit IK-51N Questions
What load can one IK-51N ball transfer unit carry?
The rated load capacity is 400 kg per unit and the maximum load capacity is 450 kg.
How is the IK-51N mounted?
It is a downward mount unit with M24 diameter mounting holes, so it is bolted from below onto a deck plate or workbench.
Which case material should I choose?
Carbon steel for general use, galvanized steel for humidity resistance, chrome-plated steel for wear, or stainless steel (SUS304) for washdown 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 IK-51N weighs 4.4 kg, which is used for deck load and shipping calculations.
Can I get other load ratings in the same series?
Yes, other models in the IK UK Series are available for different load ratings and mounting styles.
