Key Benefits

  • Carries 40 kg per unit in normal service and 60 kg at peak load
  • Spring loaded design maintains ball contact under load and reduces wear
  • Press mount fits into a pre-drilled hole so no bolts or flanges are needed
  • Steel ball and case options suit general industrial environments
  • Stainless steel case option for wet or corrosive areas

Application Scenarios

  • Transfer points between two conveyor lines running at right angles
  • Loading tables where trays are rotated by hand before entering a machine
  • Assembly stations where a component is turned between operations
  • Feeding systems for packaging machinery requiring smooth directional change
  • Processing tables where light panels are repositioned without powered guidance

Who It Is For

  • Conveyor system integrators building low load transfer points
  • Material handling equipment builders designing light-duty transfer decks
  • Assembly line builders needing manual rotation of light components
  • Industrial distributors stocking ball transfer units by load rating
  • Packaging machinery makers requiring directional flexibility in feed zones

Problems It Solves

  • Light loads that stick or drag when pushed across a fixed deck plate
  • Transfer points where product must change direction without powered diverters
  • Operators struggling to rotate a light tray or panel by hand at the end of a line
  • Decks where a single unit must handle both light and slightly heavier items
  • Systems where bolted mounts are not practical due to deck thickness or access

Technical Features

  • Spring loaded mechanism keeps the ball in contact under load
  • Press mount design fits into a clearance hole without bolts or flanges
  • 19.05 mm diameter steel ball allows smooth omnidirectional movement
  • Case available in carbon steel, galvanized steel, chrome plated steel or stainless steel
  • Unit weight of 450 g for deck load and shipping calculations

Materials

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

Quality Control

  • Load capacity verified against the 40 kg rating before packing
  • 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 carbon steel, galvanized steel, chrome plated steel and stainless steel
  • Ball material is steel, as specified
  • Other KSF Series load ratings available where 40 kg is not the right size

Use Guide

  • Divide the load by the number of units in contact to check the 40 kg per unit rating
  • Keep peak and impact loading below the 60 kg maximum load figure
  • Press the unit into a flat deck plate with a 36.5 mm diameter hole
  • Choose stainless steel case where the deck is washed down or exposed to moisture
  • Avoid using on uneven or soft-bottomed items such as cloth-wrapped loads

Compared With Other Options

Flange mount ball transfer unitsPress mount requires no bolts or flanges, so faster to install but harder to remove for service
Lower rated KSF Series unitsThe KSF-19T suits 40 kg loads, so lighter decks are better served by a smaller unit that rolls with less effort
Plain conveyor rollersBall transfer units allow movement in any direction, while rollers only move product along one axis
