Key Benefits

  • Rated for 80 kg working load and 100 kg maximum load per unit
  • Bolt down disk mount with two screw holes for secure attachment to deck or table
  • 19 mm diameter steel ball allows smooth omnidirectional movement under load
  • Steel or stainless steel case options for dry or wet environments
  • Nylon ball option available to protect painted or polished surfaces

Application Scenarios

  • Transfer tables between two conveyor lines where product must be repositioned in any direction
  • Assembly line workstations where a tray or fixture is rotated by hand
  • Packaging machinery where flat containers are moved and aligned on a deck
  • Processing tables feeding into CNC machines or routers where load rotation is required
  • Feeding systems where flat components are manually guided across a work surface

Who It Is For

  • Conveyor system integrators building transfer points with high load capacity
  • Industrial equipment builders requiring reliable ball transfer units for worktables
  • Assembly line designers needing manual repositioning of trays or fixtures
  • Material handling equipment makers building decks for heavy flat loads
  • Industrial distributors stocking ball transfer units by load and mounting type

Problems It Solves

  • Loads that jam or drag when pushed across a fixed deck due to lack of omnidirectional motion
  • Transfer points where product must change direction without powered diverters
  • Manual repositioning of heavy trays or fixtures that require precise alignment
  • Inconsistent mounting methods that lead to loose or misaligned units during operation
  • Surface damage from steel balls on painted or polished work surfaces

Technical Features

  • 19 mm diameter steel ball for high load capacity and smooth rolling
  • Bolt down disk mount with two screw holes for secure and stable attachment
  • Omnidirectional movement enabled by a spherical ball inside a restraining fixture
  • Steel case with optional galvanization, chrome plating, or stainless steel finish
  • Nylon ball option available to prevent marking on sensitive surfaces

Materials

  • Carbon steel ball and case for general industrial use
  • Galvanized steel case for improved corrosion resistance in humid environments
  • Chrome plated steel case for enhanced wear and appearance
  • Stainless steel case for wet, washdown, or corrosive environments
  • Nylon ball for non-marking contact with painted, polished, or sensitive surfaces

Quality Control

  • Load capacity verified against the 80 kg working load rating
  • Ball rotation checked by hand for free movement in all directions
  • Material grade confirmed against the case and ball option ordered
  • Mounting holes inspected for correct alignment and threading
  • Unit weight checked to ensure 220 g before packing

Customization Options

  • Ball material selected between steel and nylon
  • Case material selected between steel, galvanized steel, chrome plated steel, and stainless steel
  • Other IA IS Series load ratings available for different load requirements

Use Guide

  • Ensure the deck or table surface is flat and level to maintain even ball contact
  • Divide the total load by the number of units in contact to stay within the 80 kg per unit working load
  • Avoid using on uneven or soft-bottomed items such as cloth-wrapped goods
  • Choose nylon ball when protecting painted or polished surfaces from marking
  • Select stainless steel case for use in washdown or corrosive environments

Final inspection and packing

Compared With Other Options

Press fit ball transfer unitsBolt down disk mount allows for secure attachment and easy removal for maintenance, while press fit units are faster to install but harder to replace
Lower load rated unitsThe IA-19 suits 80 kg loads, so lighter applications may be better served by a smaller unit with less rolling resistance
Swivel castersBolt down disk mount units are designed for fixed deck use and do not support floor movement, unlike swivel casters used for mobile equipment
