Key Benefits

  • 50 kg working load and 60 kg maximum load per unit for consistent performance
  • Downward mount with two screw holes allows secure attachment to a worktable or deck plate
  • 19.05 mm diameter steel ball provides stable, omnidirectional movement for flat items
  • Available in carbon steel, galvanized steel, chrome-plated steel or stainless steel (SUS304) for different environmental needs
  • Compact 53 x 38 mm dimensions fit into tight deck spaces without interfering with adjacent components

Application Scenarios

  • Transfer points on a flat deck where trays or flat panels need to be moved in any direction
  • Feeding systems on packaging or processing machinery where items must be repositioned by hand
  • Curved work areas on band saws or router tables where continuous movement is required
  • Assembly line stations where a flat component is rotated or aligned manually
  • Conveyor integration points where a load must transition between two lines at an angle

Who It Is For

  • Conveyor system integrators building transfer points with fixed deck plates
  • Packaging machinery builders needing omnidirectional movement for tray handling
  • Industrial equipment manufacturers integrating ball transfer units into processing lines
  • Material handling equipment makers designing worktables with manual repositioning
  • Production line builders requiring consistent load handling across multiple stations

Problems It Solves

  • Loads that cannot be rotated or repositioned easily on a fixed deck plate
  • Transfer points where product must change direction without powered diverters
  • Manual alignment of flat items that require 360-degree movement on a stable platform
  • Inconsistent mounting methods that lead to loose or misaligned units during operation
  • Lack of a single-source supplier for ball transfer units with matching load and mounting specs

Technical Features

  • 19.05 mm diameter steel ball for consistent rolling under load
  • Downward mount with two screw holes for secure attachment to a deck plate
  • Steel ball and case with options for galvanized, chrome-plated or stainless steel finishes
  • 53 x 38 mm overall dimensions for compact integration into worktables
  • Mount length of 41 mm to ensure proper clearance and alignment with the deck

Materials

  • Carbon steel case and steel ball 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 and steel ball for washdown or corrosive areas

Quality Control

  • Load capacity tested against the 50 kg working load rating 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 inspected for correct size and alignment

Customization Options

  • Case material selected between carbon steel, galvanized steel, chrome-plated steel or stainless steel (SUS304)
  • Ball material is steel, no alternative materials available
  • Other IK UK Series models available for different load ratings or mounting types

Use Guide

  • Ensure the load per unit does not exceed 50 kg during normal operation
  • Keep peak or impact loads below the 60 kg maximum load limit
  • Mount the unit on a flat, rigid deck plate so all balls sit at the same height
  • Use stainless steel version in wet or washdown environments to prevent corrosion
  • Only use on flat, smooth surfaces such as trays or metal sheets—do not use on soft or uneven bottoms

Assembly of the steel ball and support structure

Step 3

Drilling and finishing of the two screw holes for mounting

Step 4

Final inspection of load capacity and ball rotation

Step 5

Packing for shipment

Compared With Other Options

Flange mount ball transfer unitsDownward mount bolts from below and is better suited for deck plates with limited space above, while flange mount units are bolted from above
Press fit ball transfer unitsDownward mount allows removal and replacement without damaging the deck, while press fit units are faster to install but harder to service
Higher rated unitsThe IK-19B is suited for 50 kg loads, so heavier applications require a larger model with higher load capacity
