Key Benefits

  • Carries 40 kg per unit in normal service and 50 kg at peak load
  • Stud mount with M8 thread allows secure attachment to workbenches and deck plates
  • Fine machined ball and seat reduce rolling resistance under load
  • Nylon ball option protects painted or polished surfaces from marking
  • Stainless steel ball and case option for wet or washdown environments

Application Scenarios

  • Transfer points on a packaging line where trays are rotated or repositioned by hand
  • Feeding systems in processing machinery where flat components need omnidirectional movement
  • Assembly stations where a fixture is turned or aligned between operations
  • Workbenches on a production line where tools or parts are moved across the surface
  • Curved work areas on router tables or band saws requiring smooth directional transfer

Who It Is For

  • Conveyor system integrators building transfer points into automated lines
  • Industrial equipment builders integrating ball transfer units into workbenches
  • Packaging machinery manufacturers needing reliable transfer points for trays
  • Production line builders requiring low-friction movement for flat components
  • Industrial distributors stocking ball transfer units by load and mounting type

Problems It Solves

  • Flat items 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 or align a load by hand at a workbench
  • Mixed-use workbenches where a single unit must handle both light and heavy items
  • Workbenches in washdown areas requiring corrosion-resistant components

Technical Features

  • Fine machined ball and seat for consistent rolling under load
  • Stud mount with M8 thread for secure attachment to workbench or deck plate
  • 19.05 mm diameter ball allows smooth movement of flat, smooth objects
  • Ball and case materials selected independently to match environment and surface
  • Unit weight of 150 g for deck load and shipping calculations

Materials

  • Nylon main 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 verified against the 40 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 40 kg is not the right size

Use Guide

  • Divide the load by the number of units in contact to ensure no more than 40 kg per unit
  • Keep peak and impact loading below the 50 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 bolts from below and is easier to install on a workbench, while flange mount requires a deck plate with a clearance hole
Lower rated D Series unitsThe D-6HT suits 40 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
