Product Overview

The KSE-12 is a spring loaded press mount ball transfer unit with a 12.7 mm diameter steel ball, rated for 30 kg working load and 50 kg maximum load. It is designed to be pressed into a hole in a flat deck plate so that a tray, panel or light component can be moved and rotated in any direction by hand. The unit weighs 160 g and is available with a steel, galvanized steel, chrome plated steel or stainless steel case.

Part of the KS KSM Series range, used in Warehouse and Distribution Centres.

Key Benefits

  • Carries 30 kg per unit in normal service and 50 kg at peak load
  • Spring loaded design maintains ball contact under light and variable loads
  • Press mount fits into a drilled hole so the unit sits flush with the deck surface
  • Steel ball and case options suit general industrial environments
  • Stainless steel case option for wet or corrosive areas

Application Scenarios

  • Transfer points between two straight conveyor lines where product must rotate 90 degrees
  • Assembly stations where a tray is moved and repositioned by hand between operations
  • Feeding systems for packaging machines handling flat components
  • Processing machinery where a panel is rotated for secondary operations
  • Workbenches with curved edges where a load must move smoothly around a radius

Who It Is For

  • Conveyor system integrators building low load transfer points
  • Material handling equipment builders designing light duty transfer decks
  • Industrial distributors stocking ball transfer units by load and mount type
  • Assembly line builders needing low profile rotation points

Problems It Solves

  • Light loads that bind or drag when pushed across a fixed deck plate
  • Transfer points where product must change direction without powered diverters
  • Operators struggling to rotate a tray or panel at the end of a line
  • Decks where a flush surface is needed and a flange mount would interfere
  • Applications where a spring loaded unit maintains ball contact under uneven load

Technical Features

  • Spring loaded mechanism keeps the ball in contact with the deck under light load
  • Press mount fits into a drilled hole and is secured by friction
  • 12.7 mm diameter steel ball for consistent rolling on flat surfaces
  • Case available in carbon steel, galvanized steel, chrome plated steel or stainless steel
  • Unit weight of 160 g for deck load and shipping calculations

Materials

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

Quality Control

  • Load capacity verified against the 30 kg 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
  • Ball material is steel and cannot be changed
  • Other KSE Series load ratings available where 30 kg is not the right size

Use Guide

  • Divide the load by the number of units in contact to check the 30 kg per unit rating
  • Keep peak and impact loading below the 50 kg maximum load figure
  • Press the unit into a hole drilled to 23.9 mm diameter for a secure fit
  • Use the stainless steel case where the deck is exposed to moisture or cleaning
  • Avoid using on uneven or soft bottom surfaces such as cloth-wrapped items

Compared With Other Options

Flange mount ball transfer unitsPress mount sits flush with the deck and requires no bolt holes, while a flange mount is bolted from above and can be removed for service
Lower rated KSE Series unitsThe KSE-12 suits 30 kg loads, so lighter decks are better served by a smaller unit that rolls with less effort
Spring loaded press mount units with nylon ballThe KSE-12 uses a steel ball, so it is better for heavy rolling on flat surfaces, while a nylon ball protects soft or painted surfaces

Spring Loaded Press Mount Ball Transfer Unit KSE-12 Questions

What load can one KSE-12 ball transfer unit carry?

The rated load capacity is 30 kg per unit and the maximum load capacity is 50 kg.

How is the KSE-12 mounted?

It is a press mount unit, so it is pressed into a drilled hole in the deck plate.

Which case material should I choose?

Carbon steel for general use, galvanized steel for better corrosion resistance, chrome plated steel for wear resistance, stainless steel for wet or washdown areas.

Is a stainless steel version available?

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

How much does the unit weigh?

Each KSE-12 weighs 160 g, which is used when calculating deck weight and shipping.

Can I get other load ratings in the same series?

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