Part of the NJ LW FB Series range, used in Sheet Metal and Press Shops.

Key Benefits

  • 250 kg working load capacity and 300 kg maximum load for heavy flat item handling
  • Disk mount with 97 mm diameter base allows secure attachment to worktables and decks
  • 38.1 mm diameter ball enables smooth omnidirectional movement of trays and rigid panels
  • Steel or stainless steel case for durability in industrial environments
  • Nylon ball option protects painted or polished surfaces from marking

Application Scenarios

  • Transfer points between two conveyor lines running at different angles
  • Feeding systems where heavy trays are rotated or repositioned by hand
  • Processing machinery worktables requiring 360-degree load movement
  • Packaging lines where flat components must be aligned without powered diverters
  • Assembly stations where a fixture is turned manually between operations

Who It Is For

  • Conveyor system integrators building high-load transfer points
  • Material handling equipment builders designing worktables and feeding stations
  • Industrial distributors stocking ball transfer units by load and mount type
  • Assembly line builders needing consistent load handling at transfer points
  • Production line designers requiring hand-rotatable load positioning

Problems It Solves

  • Heavy flat loads that jam or bind when pushed across fixed deck plates
  • Transfer points where product must change direction without powered components
  • Operators struggling to rotate or align heavy trays at the end of a line
  • Inconsistent performance when using multiple suppliers for matching ball and shaft sizes
  • Lack of a single-source solution for high-load ball transfer units with fixed mounting

Technical Features

  • 38.1 mm diameter main ball for high load capacity and stable rolling
  • Disk mount with 97 mm diameter base for secure attachment to worktables
  • Fine machined ball seat to maintain consistent rolling effort under load
  • Two screw holes in the bearing surround for solid attachment to the deck
  • Available with nylon, steel or stainless steel ball and steel or stainless steel case

Materials

  • Nylon ball for non-marking contact with painted or polished surfaces
  • Carbon steel ball and case for general industrial use
  • Stainless steel ball and case (SUS304) for wet, washdown or corrosive environments

Quality Control

  • Load capacity verified against the 250 kg working load before packing
  • Ball rotation tested by hand for free movement in all directions
  • Material grade confirmed against the ball and case option ordered
  • Mounting holes checked for alignment and thread integrity
  • Unit weight verified at 1.7 kg for shipping and deck load calculations

Customization Options

  • Ball material selected between nylon, steel and stainless steel
  • Case material selected between steel and stainless steel
  • Mount diameter and height can be adjusted for specific deck thicknesses
  • Other load ratings available in the FB Series upon request
  • Custom mounting features can be added for special deck configurations

Use Guide

  • Divide the total load by the number of units in contact to ensure no unit exceeds 250 kg working load
  • Keep peak and impact loading below the 300 kg maximum load figure
  • Mount the unit on a flat, rigid 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 exposed to washdown or corrosive conditions

Manufacturing Process

Step 1

Machining of the case and ball seat to precise dimensions

Step 2

Assembly of the ball and support bearings

Step 3

Drilling and finishing of the disk mount base

Step 4

Final load check against the 250 kg working load rating

Step 5

Packing with protective cover for shipping

Compared With Other Options

Press fit ball transfer unitsDisk mount bolts to the deck and allows for removal and replacement, while a press fit unit is faster to install but not serviceable
Lower rated FB Series unitsThe FB-005 suits 250 kg loads, so lighter applications are better served by a smaller unit that rolls with less effort
Standard roller conveyorsBall transfer units allow omnidirectional movement, while rollers only move product along one axis
