Key Benefits

  • Carries 100 kg per unit in normal service and 150 kg at peak load
  • Stud mount with M10 diameter provides strong, stable attachment to deck plates
  • Fine machined ball and seat reduce rolling resistance under heavy static load
  • Nylon ball option protects painted or polished surfaces from marking
  • Stainless steel ball and case option for wet, washdown or corrosive environments

Application Scenarios

  • Transfer points between two conveyor lines running at right angles in a packaging line
  • Worktables in processing machinery where flat trays or components need to be repositioned
  • Feeding systems where a load must be moved in any direction by hand
  • Assembly stations requiring manual rotation of fixtures or tools
  • Router tables or band saws where a workpiece needs omnidirectional movement

Who It Is For

  • Conveyor system integrators building transfer points with manual repositioning
  • Industrial equipment builders designing worktables with adjustable positioning
  • Packaging machinery manufacturers needing reliable load transfer points
  • Assembly line builders integrating manual alignment stations
  • Industrial distributors stocking ball transfer units by load and mount type

Problems It Solves

  • Loads that bind or jam when pushed across a fixed deck plate or plain rollers
  • Transfer points where product must change direction without powered diverters
  • Operators struggling to rotate or align a load by hand at the end of a line
  • Inconsistent mounting methods when combining components from multiple suppliers
  • Lack of a single-source solution for stud mount units with matching load and material options

Technical Features

  • Fine machined ball and seat rather than pressed or stamped components
  • Stud mount with M10 diameter for secure bolted attachment to deck plates
  • Main ball supplied in nylon, steel or stainless steel to match surface requirements
  • Case supplied in steel or stainless steel for dry or wet environments
  • Unit weight of 210 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 decks
  • Stainless steel ball and case for wet, washdown or corrosive areas

Quality Control

  • Load capacity checked against the 100 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 100 kg is not the right size

Use Guide

  • Divide the load by the number of units in contact to check the 100 kg per unit rating
  • Keep peak and impact loading below the 150 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 through the deck and allows for easier removal and replacement, while flange mount is fixed from above
Press fit ball transfer unitsStud mount provides a more secure and serviceable attachment than a press fit, which is harder to remove
Lower rated D Series unitsThe D-8H suits 100 kg loads, so lighter decks are better served by a smaller unit that rolls with less effort
