Key Benefits

  • Carries 50 kg per unit in normal service and 60 kg at peak load
  • Downward mount with M12 thread fixes the unit from below, allowing secure attachment to a worktable
  • 19 mm diameter steel ball provides stable rolling under moderate load
  • Steel or stainless steel case options suit dry, wet or washdown environments
  • Two screw holes around the bearing allow solid attachment to the mounting surface

Application Scenarios

  • Transfer points on a flat worktable where trays or flat components need to be repositioned by hand
  • Assembly lines with rotating stations where a fixture must be turned without powered movement
  • Feeding systems for packaging machinery where flat items are aligned and moved between stations
  • Processing machinery with curved work surfaces where omnidirectional movement is needed
  • Conveyor integration points where a flat load must be transferred between two lines at an angle

Who It Is For

  • Conveyor system integrators building manual transfer or alignment points
  • Industrial equipment builders designing worktables with movable platforms
  • Packaging machinery manufacturers needing omnidirectional movement in feed zones
  • Assembly line designers requiring hand-rotatable positioning for fixtures
  • Material handling equipment makers sourcing downward ball transfer units by load and mount type

Problems It Solves

  • Flat loads that cannot be rotated or repositioned easily on a fixed table surface
  • Transfer points where product must change direction without powered diverters
  • Worktables where a fixture or tray must be moved in any direction by hand
  • Mounting systems that require a secure, non-press fit attachment method
  • Areas where a standard caster or roller cannot be used due to floor contact or load type

Technical Features

  • 19 mm diameter steel ball for consistent rolling under moderate load
  • Downward mount with M12 threaded hole for attachment from below the deck
  • Two screw holes around the bearing for secure fastening to the worktable
  • Steel case with optional galvanizing, chrome plating or stainless steel finish
  • Compact 42 x 58 mm dimension for tight space applications

Materials

  • Carbon steel ball and case for general industrial use
  • Galvanized steel case for improved corrosion resistance in humid environments
  • Chrome plated case for enhanced wear resistance and appearance
  • Stainless steel (SUS304) case for wet, washdown or food handling applications

Quality Control

  • Load capacity verified against the 50 kg working load rating
  • Ball rotation checked by hand for free movement in all directions
  • Material grade confirmed against the case option ordered

Customization Options

  • Case material selected between steel, galvanized steel, chrome plated, or stainless steel
  • Ball material is steel, as specified; no nylon option available
  • Other models in the IK UK Series available for different load or mount requirements

Use Guide

  • Ensure the load per unit does not exceed 50 kg under normal use
  • Keep peak or impact loading below the 60 kg maximum load capacity
  • Mount the unit into a flat, rigid deck plate to maintain ball alignment
  • Use stainless steel case where the environment is wet or requires washdown
  • Avoid use with soft or uneven bottomed items such as cloth-wrapped goods

Compared With Other Options

Flange mount ball transfer unitsDownward mount fixes from below, allowing a flush deck surface, while flange mount requires clearance from above
Press fit ball transfer unitsDownward mount uses threaded attachment for secure, serviceable installation, unlike press fit which is harder to remove
Standard castersDownward ball transfer units are designed for flat surface movement, not floor rolling, and do not support uneven or soft-bottomed loads
