Downward Ball Transfer Unit IK-51B
The IK-51B is a downward ball transfer unit with a 51 mm diameter steel ball, rated for 300 kg working load and 350 kg maximum load. It mounts through a 102 mm diameter hole in a deck plate with two screw holes for secure attachment. The unit weighs 5.3 kg and is available with a steel, galvanized steel, chrome plated steel or stainless steel case. It allows omnidirectional movement of flat, smooth objects like trays across a conveyor or work surface.

Part of the IK UK Series range, used in Warehouse and Distribution Centres.
Key Benefits
- 300 kg working load and 350 kg maximum load per unit for heavy-duty transfer
- Downward mount design allows direct installation through a deck plate with two screw holes
- 51 mm diameter steel ball enables smooth, omnidirectional movement of flat loads
- Steel, galvanized steel, chrome plated steel or stainless steel case options for different environments
- Compact 130 x 100 mm size fits into tight deck space while supporting high load
Application Scenarios
- Transfer points in a conveyor line where heavy trays need to be redirected without powered diverters
- Worktables on assembly lines where large flat components must be rotated or repositioned by hand
- Packaging stations where trays are moved in any direction across a fixed deck
- Processing machinery feed systems requiring stable, low-friction movement of rigid flat items
- Curved sections of router tables or band saws where continuous directional control is needed
Who It Is For
- Conveyor system integrators building high-load transfer points
- Industrial equipment builders designing worktables with manual repositioning
- Packaging line designers needing omnidirectional movement for trays
- Assembly line engineers integrating manual alignment stations
- Material handling contractors sourcing consistent ball transfer units by load and mount type
Problems It Solves
- Heavy flat loads that jam or bind when pushed across a fixed deck due to high rolling resistance
- Transfer points requiring 360-degree movement but lacking powered or complex mechanisms
- Inconsistent mounting methods across different units in a single system
- Deck plates with multiple transfer units that require uniform height and alignment
- Lack of a single supplier for ball transfer units with consistent load rating and mounting dimensions
Technical Features
- 51 mm diameter steel ball for high load capacity and durability
- Downward mount with two screw holes for secure attachment to deck plate
- 102 mm mounting diameter fits standard deck hole sizes
- Omnidirectional ball bearing design allows movement in any direction
- Case made from carbon steel, galvanized steel, chrome plated steel or stainless steel (SUS304)
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 (SUS304) case for washdown, food, or corrosive environments
Quality Control
- Load capacity verified against the 300 kg working load rating
- Ball rotation checked by hand for free movement in all directions
- Material grade confirmed against the case material option ordered
- Mounting diameter and screw hole alignment verified before packing
Customization Options
- Case material selected between carbon steel, galvanized steel, chrome plated steel or stainless steel (SUS304)
- Ball material is steel only, as specified
- Other models in the IK UK Series available for different load or mounting requirements
Use Guide
- Ensure the deck plate has a 102 mm hole for downward mounting
- Check that all units are mounted at the same height to avoid load imbalance
- Distribute the load evenly across multiple units to stay within the 300 kg per unit rating
- 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

Compared With Other Options
| Upward ball transfer units | Downward mount allows direct deck plate installation with two screws, while upward units require a recessed mount or frame |
|---|---|
| Press fit ball transfer units | Downward mount with screw holes allows secure attachment and easier replacement than press fit units |
| Lower load rated units | The IK-51B suits 300 kg loads, so lighter applications may benefit from a smaller unit with lower rolling resistance |
