Product Overview

The UK-19T is a downward ball transfer unit with a 19.05 mm diameter steel ball, rated for 50 kg working load and 80 kg maximum load. It mounts through a 60 mm diameter hole from below the deck plate, allowing a flat, smooth object like a tray to be moved in any direction by hand. The unit weighs 3 kg and is available with a steel, galvanized steel, chrome-plated steel or stainless steel case.

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

Key Benefits

  • Carries 50 kg per unit in normal service and 80 kg at peak load
  • Downward mount bolts from below the deck plate, allowing access for maintenance
  • 19.05 mm diameter ball provides stable rolling for flat, smooth trays and panels
  • Steel or stainless steel case options suit dry, wet or washdown environments
  • Two screw holes in the base allow secure attachment to worktables and benches

Application Scenarios

  • Transfer points on a flat deck where trays or panels need to be repositioned by hand
  • Feeding systems in packaging or processing machinery where items must be rotated
  • Workbenches on assembly lines where a fixture is moved between operations
  • Curved work surfaces on band saws or router tables requiring omnidirectional movement
  • Conveyor integration points where a flat load changes direction without powered diverters

Who It Is For

  • Conveyor system integrators building transfer points with downward mounting
  • Industrial equipment builders designing worktables with manual repositioning
  • Packaging and processing machinery manufacturers needing low-load transfer units
  • Assembly line builders integrating manual positioning stations into production lines
  • Industrial distributors stocking downward ball transfer units by load and mount type

Problems It Solves

  • Flat loads that cannot be rotated or repositioned easily on a fixed deck
  • Transfer points where product must change direction without powered mechanisms
  • Worktables that require stable, low-friction movement for trays or panels
  • Mounting constraints where space above the deck is limited
  • Need for a consistent range of downward-mounted units with known load ratings

Technical Features

  • 19.05 mm diameter steel ball for consistent rolling on flat surfaces
  • Downward mount with 60 mm diameter hole for installation from below the deck
  • Steel case with options for galvanizing, chrome plating or stainless steel finish
  • Two screw holes in the base for secure attachment to worktables or benches
  • Unit weight of 3 kg for deck load and shipping calculations

Materials

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

Quality Control

  • Load capacity verified against the 50 kg working load rating before packing
  • Ball rotation checked by hand for free movement in all directions
  • Material grade confirmed against the case option ordered

Customization Options

  • Case material selected between carbon steel, galvanized steel, chrome-plated steel and stainless steel (SUS304)
  • Ball material is steel, as specified in the standard configuration
  • Other UK Series models available for different load ratings and mounting types

Use Guide

  • Divide the load by the number of units in contact to ensure each unit stays under 50 kg working load
  • Keep peak and impact loading below the 80 kg maximum load figure
  • Mount the unit on a flat deck plate so the ball sits at the same height as adjacent units
  • Use the stainless steel case where the deck is exposed to washdown or corrosive conditions
  • Avoid using on uneven or soft-bottomed items like cloth-wrapped goods

Compared With Other Options

Upward ball transfer unitsDownward mount allows installation from below the deck, ideal where space above is limited
Press fit ball transfer unitsDownward mount bolts through the deck, allowing removal for maintenance, unlike press-fit units
Higher load rated unitsThe UK-19T is suited for 50 kg loads; heavier applications require a larger model in the same series
