Downward Ball Transfer Unit UK-50T

The UK-50T is a downward ball transfer unit with a 50 mm diameter steel ball, rated for 300 kg working load and 350 kg maximum load. It mounts through a downward flange onto a deck plate or workbench, allowing heavy flat items like trays to be moved and rotated in any direction by hand. The unit weighs 15 kg and is available with a steel, galvanized steel, chrome-plated steel, or stainless steel case. It is designed for high-load transfer points in industrial handling systems.

Part of the IK UK Series range, used in Warehouse and Distribution Centres.

Key Benefits

  • Carries 300 kg per unit in normal service and 350 kg at peak load
  • Downward mount allows secure attachment to deck plates with two threaded holes
  • 50 mm diameter steel ball provides stable rolling under heavy static and dynamic loads
  • Steel case options suit general industrial environments; stainless steel version for wet or corrosive areas
  • Omni-directional movement enables rotation and repositioning of flat, rigid loads

Application Scenarios

  • Transfer points between two conveyor lines running at right angles in a warehouse system
  • Loading tables for heavy trays or sheet metal in assembly or packaging lines
  • Workbenches on processing machinery where a flat component must be repositioned by hand
  • Curved sections of band saws or router tables requiring smooth directional change
  • Feeding systems where a rigid flat item needs to be aligned or rotated without powered guidance

Who It Is For

  • Conveyor system integrators building high-load transfer points
  • Industrial equipment builders designing workstations with manual repositioning
  • Packaging line designers needing reliable transfer for heavy trays
  • Assembly line builders integrating manual rotation stations
  • Material handling contractors sourcing consistent high-load ball transfer units

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
  • Workstations where a heavy tray or panel must be rotated by hand without resistance
  • Systems requiring a single consistent load rating across multiple transfer points
  • Need for a downward-mounted unit that stays fixed and does not shift during use

Technical Features

  • 50 mm diameter steel ball for high load capacity and durability
  • Downward mount with two threaded holes for secure attachment to deck plates
  • Housing made from carbon steel, galvanized steel, chrome-plated steel, or stainless steel (SUS304)
  • Case dimensions of 195 mm diameter and 106 mm height for consistent deck integration
  • Mounting diameter of 158 mm to fit standard deck hole patterns
  • Unit weight of 15 kg for deck load and shipping planning

Materials

  • Carbon steel ball and case for general industrial use
  • Galvanized steel case for improved corrosion resistance in moderate environments
  • Chrome-plated steel case for wear resistance and appearance
  • Stainless steel (SUS304) case for wet, washdown, or corrosive areas

Quality Control

  • Load capacity verified against the 300 kg working load rating
  • Ball rotation checked by hand to ensure free movement in all directions
  • Material grade confirmed against the case option ordered
  • Mounting holes inspected for correct diameter and thread depth

Customization Options

  • Case material selected between carbon steel, galvanized steel, chrome-plated steel, and stainless steel (SUS304)
  • Other UK Series load ratings available where 300 kg is not the right size
  • Mounting configuration limited to downward mount with two threaded holes

Use Guide

  • Divide the total load by the number of units in contact to ensure no unit exceeds 300 kg working load
  • Keep peak and impact loading below the 350 kg maximum load figure
  • Mount the unit on a flat, rigid deck plate so all balls sit at the same height
  • Use stainless steel case where the deck is exposed to water, cleaning agents, or corrosive substances
  • Avoid use with soft or uneven bottom surfaces such as cloth-wrapped items or flexible packaging

Manufacturing Process

Step 1

Machining of the case and mounting flange

Step 2

Assembly of the 50 mm steel ball and support structure

Step 3

Drilling and threading of two mounting holes for secure attachment

Step 4

Final inspection of load capacity and ball rotation

Step 5

Packing for shipping and storage

Compared With Other Options

Upward ball transfer unitsDownward mount fixes the unit from below, preventing upward movement during load transfer, while upward units are mounted from above and may shift under load
Press fit ball transfer unitsDownward mount allows removal and replacement without damaging the deck, while press fit units are faster to install but harder to service
Lower rated UK Series unitsThe UK-50T suits 300 kg loads, so lighter applications are better served by a smaller unit that rolls with less effort

Downward Ball Transfer Unit UK-50T Questions

What load can one UK-50T ball transfer unit carry?

The rated load capacity is 300 kg per unit and the maximum load capacity is 350 kg.

How is the UK-50T mounted?

It is a downward mount unit, so it is attached through two threaded holes from below the deck plate.

Which case material should I choose?

Carbon steel for general use, galvanized for corrosion resistance, chrome-plated for wear and appearance, stainless steel (SUS304) for wet or washdown environments.

Is a stainless steel version available?

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

How much does the unit weigh?

Each UK-50T weighs 15 kg, which is used for deck load and shipping calculations.

Can I get other load ratings in the same series?

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