Product Overview

The KSF-45 is a spring loaded press mount ball transfer unit with a 45 mm diameter steel ball, rated for 250 kg working load and 280 kg maximum load. It is designed to be pressed into a hole in a deck plate so that a flat, smooth object like a tray can be moved and rotated in any direction by hand. The unit weighs 2.12 kg and is available with a steel, galvanized steel, chrome plated, or stainless steel case.

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

Key Benefits

  • Carries 250 kg per unit in normal service and 280 kg at peak load
  • Spring loaded design maintains consistent ball contact under varying load and deck deflection
  • Press mount installs directly into a pre-drilled hole without additional fasteners
  • 45 mm diameter ball allows smooth movement of large flat trays and panels
  • Steel or stainless steel case options suit dry, wet or washdown environments

Application Scenarios

  • Transfer points between two conveyor lines where trays must be rotated 90 degrees
  • Assembly stations where a large panel needs to be repositioned by hand
  • Feeding systems for packaging machinery requiring omnidirectional movement
  • Processing tables where flat components are moved and aligned without powered drives
  • Curved work surfaces on band saws or router tables where continuous motion is needed

Who It Is For

  • Conveyor system integrators building high load transfer points
  • Material handling equipment builders designing deck sections with press mount units
  • Industrial distributors stocking ball transfer units by load and mount type
  • Production line builders requiring durable units for heavy flat loads
  • Warehouse automation contractors installing manual transfer zones

Problems It Solves

  • Heavy flat loads that bind or jam when pushed across a fixed deck plate
  • Transfer points where product must change direction without powered diverters
  • Deck deflection causing uneven ball contact and increased rolling effort
  • Need for a unit that stays in place without bolts or flanges on the deck surface
  • Lack of consistent load rating across multiple suppliers for a single deck design

Technical Features

  • Spring loaded mechanism maintains ball contact under load and deck flex
  • 45 mm diameter steel ball for high load capacity and durability
  • Press mount design fits into a 45 mm diameter hole in the deck plate
  • Case available in carbon steel, galvanized steel, chrome plated steel or stainless steel
  • Overall dimensions of 86 mm diameter and 101.5 mm height for deck space planning

Materials

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

Quality Control

  • Load capacity tested against the 250 kg working load rating
  • Spring function checked to ensure consistent ball pressure under load
  • 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; no other ball materials are available for this model
  • Other KSF Series load ratings available where 250 kg is not the right size

Use Guide

  • Ensure the deck plate has a 45 mm diameter hole for press fit installation
  • Verify that the load per unit does not exceed 250 kg during normal operation
  • Keep peak and impact loading below the 280 kg maximum load figure
  • Use stainless steel case where the deck is exposed to washdown or corrosive conditions
  • Do not use on uneven or soft bottom surfaces such as cloth-wrapped items

Compared With Other Options

Flange mount ball transfer unitsPress mount requires no bolts or flanges, saving deck space and simplifying installation, but is harder to remove for service
Lower rated KSF Series unitsThe KSF-45 suits 250 kg loads, so lighter applications are better served by a smaller unit that rolls with less effort
Spring loaded press mount with nylon ballThis unit uses a steel ball for high load and wear resistance, while a nylon ball unit is better for protecting delicate surfaces but has lower load capacity

Spring Loaded Press Mount Ball Transfer Unit KSF-45 Questions

What load can one KSF-45 ball transfer unit carry?

The rated load capacity is 250 kg per unit and the maximum load capacity is 280 kg.

How is the KSF-45 mounted?

It is a press mount unit, so it is pressed into a 45 mm diameter hole in the deck plate.

Which case material should I choose?

Carbon steel for general use, galvanized steel for humidity resistance, chrome plated steel for wear resistance, stainless steel (SUS304) for washdown or corrosive areas.

Is a stainless steel version available?

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

How much does the unit weigh?

Each KSF-45 weighs 2.12 kg, which is used for deck load and shipping calculations.

Can I get other load ratings in the same series?

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