Key Benefits

  • 250 kg working load capacity and 300 kg maximum load for heavy-duty handling
  • Flange mount with two screw holes allows secure attachment and easy removal for maintenance
  • 30.16 mm diameter ball enables smooth omnidirectional movement of flat, rigid loads
  • Nylon ball option prevents marking on painted or polished surfaces
  • Stainless steel case and ball option suitable for washdown or corrosive environments

Application Scenarios

  • Transfer points between two conveyor lines running at right angles or diagonal angles
  • Feeding systems in packaging machinery where trays or flat components need to be repositioned
  • Processing tables in machining or assembly lines where a heavy fixture must be rotated by hand
  • Curved work surfaces on band saws or router tables requiring continuous load transfer
  • Material handling decks in automated systems where a single unit must support consistent heavy loads

Who It Is For

  • Conveyor system integrators building high-load transfer points
  • Industrial equipment builders requiring durable ball transfer units for processing tables
  • Packaging machinery manufacturers integrating transfer decks into feeding lines
  • Assembly line designers needing hand-rotatable platforms for heavy fixtures
  • Industrial distributors stocking ball transfer units by load rating and mounting type

Problems It Solves

  • Heavy flat loads that jam or bind when pushed across a fixed deck plate
  • Transfer points where product must change direction without powered diverters
  • Operators struggling to rotate or align a heavy load by hand at the end of a line
  • Inconsistent performance when using multiple low-capacity units on a single deck
  • Lack of a single supplier for matched ball transfer units with consistent load ratings

Technical Features

  • Fine machined ball and seat for consistent rolling under heavy static load
  • Flange mount with two screw holes for secure attachment to a deck or table
  • 30.16 mm diameter ball allows smooth omnidirectional movement of flat items
  • 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

Materials

  • Nylon main 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 checked by hand for free movement in all directions
  • Material grade confirmed against the ball and case option ordered
  • Flange and mounting holes inspected for correct alignment and finish

Customization Options

  • Ball material selected between nylon, steel, and stainless steel
  • Case material selected between steel and stainless steel
  • Other load ratings available in the FB Series where 250 kg is not the right size

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 units 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 moisture

Step 5

Final inspection and packaging

Compared With Other Options

Press fit ball transfer unitsFlange mount allows removal and replacement without damaging the deck, while press fit units are faster to install but harder to service
Lower rated FB Series unitsThe FB-025 suits 250 kg loads, so lighter applications are better served by smaller units that roll with less effort
Standard roller bearingsBall transfer units allow omnidirectional movement, while roller bearings only move product along one axis

Customized Mahcined Ball Transfer Unit FB-025 Questions

What load can one FB-025 ball transfer unit carry?

The rated load capacity is 250 kg per unit and the maximum load capacity is 300 kg.

How is the FB-025 mounted?

It is a flange mount unit with two screw holes, so it is bolted to the deck plate rather than pressed in.

Which ball material should I choose?

Nylon for surfaces that must not be marked, steel for general use, and stainless steel for wet or washdown areas.

Is a stainless steel version available?

Yes, both the ball and the case can be supplied in stainless steel (SUS304).

How much does the unit weigh?

Each FB-025 weighs 430 g, which is used for deck load and shipping calculations.

Can I get other load ratings in the same series?

Yes, the FB Series includes other load ratings, so ask for the model that matches your load per unit.
