Key Benefits

  • Carries 40 kg per unit in normal service and 45 kg at peak load
  • Screw mount with two M44 diameter holes allows secure attachment to deck plates
  • 22 mm diameter ball provides stable support for flat, smooth objects
  • 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 between two conveyor lines where product must be rotated or repositioned by hand
  • Feeding tables in packaging or processing machinery where trays are moved in multiple directions
  • Assembly stations requiring manual reorientation of flat components
  • Workbenches with curved or angled surfaces where omnidirectional movement is needed
  • Conveyor decks where a consistent load rating is required across multiple transfer points

Who It Is For

  • Conveyor system integrators building transfer and rotation points into material handling lines
  • Industrial equipment builders designing feeding and processing tables
  • Packaging machinery manufacturers needing omnidirectional movement for trays
  • Material handling equipment makers integrating ball transfer units into custom decks
  • Industrial distributors stocking ball transfer units by load rating and mounting type

Problems It Solves

  • Loads that jam or bind when pushed across a fixed deck plate or plain rollers
  • Transfer points where product must change direction without powered diverters
  • Operators struggling to reposition flat items by hand at the end of a line
  • Mixed-duty decks where a single load rating must support both light and heavy items
  • Mounting systems that require secure attachment without press fitting or welding

Technical Features

  • 22 mm diameter ball with fine machined seat for consistent rolling under load
  • Screw mount with two M44 diameter holes for secure attachment to deck plates
  • Main ball available in nylon, steel or stainless steel to match surface requirements
  • Case available in steel or stainless steel for dry or wet environments
  • Unit weight of 280 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 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 LW 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 45 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

Press mount ball transfer unitsScrew mount allows secure attachment and easy removal for service, while a press fit unit is faster to install but harder to replace
Lower rated LW Series unitsThe LW-22 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
