Key Benefits

  • 180 kg working load and 200 kg maximum load per unit for heavy-duty handling
  • Pipe mount design fits tubes with 30.16 mm diameter for direct installation
  • Steel ball and case options provide durability in industrial environments
  • Two screw holes allow secure mounting to worktables or benches
  • Omni-directional movement enables rotation and repositioning of flat loads

Application Scenarios

  • Transfer points on a conveyor line where trays or flat panels need to be rotated between stations
  • Assembly lines where a fixture must be turned by hand without powered alignment
  • Packaging machinery where flat items are reoriented before sealing or labeling
  • Processing tables where a tray is moved laterally or rotated during machining
  • Feeding systems where a flat component is guided into a machine with directional flexibility

Who It Is For

  • Conveyor system integrators building transfer and orientation points
  • Industrial equipment builders integrating ball transfer units into worktables
  • Assembly line designers needing manual repositioning of fixtures
  • Material handling equipment makers building modular workstations
  • Industrial distributors stocking pipe mount ball transfer units by load rating

Problems It Solves

  • Flat loads that cannot be rotated or repositioned on fixed rollers or straight tracks
  • Transfer points where product must change direction without powered diverters
  • Workstations where operators must manually align a tray or panel by pushing
  • Systems requiring a fixed mounting method that does not rely on press-fit or adhesive
  • Applications where a single unit must support high load while remaining compact

Technical Features

  • 30.16 mm diameter steel ball for consistent rolling under heavy static load
  • Pipe mount design with 30.16 mm internal diameter to fit standard tubing
  • Two screw holes in the bearing surround for secure attachment to a surface
  • Steel case with optional galvanizing, chrome plating, or stainless steel finish
  • Compact 45 x 38 mm dimension for space-constrained installations

Materials

  • Carbon steel ball and case for general industrial use
  • Galvanized steel case for improved corrosion resistance in humid environments
  • Chrome plated case for wear resistance and a smoother surface
  • Stainless steel (SUS304) case for washdown, food, or chemical exposure

Quality Control

  • Load capacity tested against the 180 kg working load before packing
  • Ball rotation checked by hand for free movement in all directions
  • Material grade confirmed against the case option ordered
  • Mount diameter verified to match 30.16 mm for proper pipe fit

Customization Options

  • Case material selected between carbon steel, galvanized steel, chrome plated, or stainless steel
  • Ball material is steel; no other ball material is available for this model
  • Other KSM Series models available for different load ratings or mounting types

Use Guide

  • Ensure the mounting tube diameter is 30.16 mm to match the unit's internal fit
  • Divide the total load by the number of units in contact to stay within the 180 kg working load
  • Keep peak and impact loading below the 200 kg maximum load limit
  • Use stainless steel case where exposure to water, cleaning agents, or food contact is expected
  • Avoid using on uneven or soft-bottomed items such as cloth-wrapped goods

Manufacturing Process

Step 1

Machining of the case and internal ball seat

Step 2

Assembly of the steel ball and bearing components

Step 3

Drilling and finishing of the two mounting screw holes

Step 4

Final inspection of load capacity and rotation smoothness

Step 5

Packing for shipping and storage

Compared With Other Options

Flange mount ball transfer unitsPipe mount fits directly onto a tube, while flange mount requires a deck plate and bolt holes
Press fit ball transfer unitsPipe mount allows removal and replacement without damaging the mounting tube, unlike press fit which is permanent
Lower rated KSM Series unitsThe KSM-30 suits 180 kg loads, so lighter applications are better served by a smaller unit with less resistance
