Key Benefits

  • Carries 25 kg per unit in normal service and 30 kg at peak load
  • Disk mount with central hole allows simple bolt-through installation
  • 1-inch diameter ball provides stable rolling for medium-weight loads
  • Steel or stainless steel case options suit dry, wet or corrosive environments
  • Nylon ball option protects painted or polished surfaces from marking

Application Scenarios

  • Transfer points between two conveyor lines running at an angle
  • Feeding tables where a medium-weight part needs to be rotated by hand
  • Assembly line stations where a fixture must be repositioned in any direction
  • Packaging line transfer decks where cartons are manually aligned
  • Processing machinery where a workpiece is moved across a curved surface

Who It Is For

  • Conveyor system integrators building transfer and rotation points
  • Material handling equipment builders designing manual handling decks
  • Industrial distributors stocking ball transfer units by load rating
  • Assembly line builders needing low-friction rotation for fixtures
  • Warehouse automation contractors installing manual transfer zones

Problems It Solves

  • Medium loads that stick or jam 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 the end of a line
  • Mixed-use decks where a single unit must handle both light and heavy items
  • Decks requiring a balance between load capacity and compact footprint

Technical Features

  • Pressed ball housing with a central mounting hole for disk mount
  • 1-inch diameter ball provides consistent contact with load surfaces
  • Ball and case materials selected independently to match the environment
  • Central hole diameter of 5 mm allows standard M5 or similar fasteners
  • Overall dimensions of 70 mm diameter by 28 mm height for deck space planning

Materials

  • Steel ball and case for general industrial use
  • Galvanized or chrome-plated case for improved corrosion resistance
  • Stainless steel ball and case for wet, washdown or corrosive areas
  • Nylon ball for non-marking contact with painted or polished surfaces

Quality Control

  • Load capacity verified against the 25 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
  • Mounting hole diameter measured to ensure 5 mm tolerance

Customization Options

  • Ball material selected between steel, stainless steel, and nylon
  • Case material selected between steel, galvanized, chrome plated, and stainless steel
  • Other CY Series load ratings available where 25 kg is not the right size

Use Guide

  • Divide the load by the number of units in contact to ensure no more than 25 kg per unit
  • Keep peak and impact loading below the 30 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 or exposed to moisture

Compared With Other Options

Flange mount ball transfer unitsDisk mount has a smaller footprint and is easier to install with a single bolt, while flange mount offers more secure mounting from above
Lower rated CY Series unitsThe CY-25B suits 25 kg loads, so lighter decks are better served by a smaller unit that rolls with less effort
Higher rated CY Series unitsThe CY-25B is designed for medium loads; heavier applications require a unit with a higher load rating
