Product Overview

The IK-38N is a downward ball transfer unit with a 38.1 mm diameter steel ball, rated for 150 kg working load and 200 kg maximum load. It mounts through a downward flange with M22 diameter mounting holes and is available in carbon steel, galvanized steel, chrome plated steel, or stainless steel (SUS304) case. The unit weighs 2.1 kg and is designed for flat, smooth surfaces such as trays, trays, and deck plates in material handling systems.

Part of the IK UK Series range, used in Warehouse and Distribution Centres.

Key Benefits

  • 150 kg working load and 200 kg maximum load for stable transfer of heavy flat items
  • Downward mount with M22 diameter mounting holes allows secure attachment to worktables
  • 38.1 mm diameter steel ball enables smooth 360-degree movement of flat loads
  • Available in carbon steel, galvanized, chrome plated, or stainless steel for different environment needs
  • Two screw holes in the bearing surround ensure solid attachment to the work surface

Application Scenarios

  • Transfer points on curved worktables for band saws and router machines
  • Feeding systems where flat trays or components need to be moved in any direction
  • Processing machinery with rotating or adjustable workstations requiring omnidirectional load transfer
  • Packaging lines where trays are repositioned manually without powered diverters
  • Assembly lines with workstations that require load rotation or alignment by hand

Who It Is For

  • Conveyor system integrators building transfer points with downward mounting
  • Material handling equipment builders designing worktables with omnidirectional movement
  • Industrial machinery manufacturers integrating ball transfer units into processing systems
  • Assembly line builders needing manual repositioning of flat components
  • Industrial distributors stocking downward ball transfer units by load and mounting type

Problems It Solves

  • Flat loads that cannot be rotated or repositioned easily on fixed or linear conveyor sections
  • Worktables that require 360-degree movement without powered swivels or complex mechanisms
  • Mounting challenges where a downward flange provides a stable, non-press fit attachment
  • Need for consistent load transfer across multiple units on a single deck plate
  • Lack of a single-source supplier for downward ball transfer units with matching shaft and load ratings

Technical Features

  • 38.1 mm diameter steel ball for high load capacity and smooth rolling
  • Downward mount with M22 diameter mounting holes for secure attachment
  • Steel case with optional galvanizing, chrome plating, or stainless steel (SUS304) for corrosion resistance
  • Two screw holes in the bearing surround for firm mounting to worktables
  • Overall dimensions of 80 x 115 mm (Diameter x Height) for space 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 for washdown, food, or corrosive environments

Quality Control

  • Load capacity verified against the 150 kg working load rating
  • Ball rotation checked by hand for free movement in all directions
  • Material grade confirmed against the case option ordered
  • Mounting holes inspected for correct M22 diameter and alignment

Customization Options

  • Case material selected between carbon steel, galvanized steel, chrome plated steel, or stainless steel (SUS304)
  • Ball material is steel; no nylon option available
  • Other models in the IK UK Series available for different load ratings or mounting types

Use Guide

  • Ensure the load is flat and smooth to prevent jamming or uneven wear
  • Distribute the load across multiple units to stay within the 150 kg per unit working load
  • Keep peak and impact loading below the 200 kg maximum load limit
  • Use stainless steel case in washdown or corrosive environments
  • Mount on a flat, rigid surface so all balls sit at the same height

Compared With Other Options

Upward ball transfer unitsDownward mount fixes the unit from below, allowing the deck to remain flat and clear, while upward units protrude from the top
Press fit ball transfer unitsDownward mount uses bolts for secure attachment and easier replacement, while press fit units are faster to install but harder to service
Lower load rated unitsThe IK-38N suits 150 kg working load, so lighter applications may be better served by a smaller unit with less weight and lower cost
