Key Benefits

  • Carries 5 kg per unit in normal service and 6 kg at peak load
  • Stud mount with M6 thread allows secure attachment to a tapped hole in a worktable
  • Fine machined ball and seat reduce rolling resistance under light load
  • Nylon ball option protects painted or polished surfaces from marking
  • Stainless steel ball and case option for use in wet or washdown environments

Application Scenarios

  • Transfer points on a flat worktable where a tray or panel must be moved in any direction
  • Feeding systems in packaging machinery where a flat item needs to be repositioned
  • Processing machinery with a curved work surface requiring omnidirectional movement
  • Assembly stations where a fixture is rotated by hand between operations
  • Conveyor integration points where a light load must be transferred between lines

Who It Is For

  • Conveyor system integrators building light-duty transfer points
  • Material handling equipment builders designing worktables with movable decks
  • Industrial distributors stocking ball transfer units by load rating
  • Assembly line builders needing low-friction movement for small components

Problems It Solves

  • Light loads that stick or drag when pushed across a fixed deck plate
  • Transfer points where a flat item must be repositioned without powered guidance
  • Operators struggling to align a small panel or tray by hand at a workbench
  • Worktables requiring a compact, low-profile mounting solution with minimal deck penetration

Technical Features

  • Fine machined ball and seat for consistent rolling under light static load
  • Stud mount with M6 thread for secure attachment to a tapped hole
  • Ball diameter of 6.35 mm (0.25 inch) for precise fit and smooth motion
  • Case and ball materials selected from steel or stainless steel to suit environment
  • Unit weight of 35 g for deck load and shipping calculations

Materials

  • Nylon ball for non marking contact with painted or polished surfaces
  • Carbon steel ball and case for general industrial use
  • Stainless steel ball and case for wet, washdown or corrosive environments

Quality Control

  • Load capacity checked against the 5 kg rating before packing
  • Ball rotation checked by hand for free movement in all directions
  • Material grade confirmed against the ball and case option ordered

Customization Options

  • Ball material selected between nylon, steel and stainless steel
  • Case material selected between steel and stainless steel
  • Other D Series load ratings available where 5 kg is not the right size

Use Guide

  • Divide the load by the number of units in contact to check the 5 kg per unit rating
  • Keep peak and impact loading below the 6 kg maximum load figure
  • Mount units on a flat deck plate so all balls sit at the same height
  • Choose the nylon ball where the load surface must not be marked
  • Choose stainless steel ball and case where the deck is washed down

Compared With Other Options

Flange mount ball transfer unitsStud mount fits into a tapped hole and is more compact, while flange mount bolts from above and allows easier removal
Lower rated D Series unitsThe D-2H suits 5 kg loads, so lighter applications 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
