Spring Loaded Press Mount Ball Transfer Unit KSF-45
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.
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 units | Press mount requires no bolts or flanges, saving deck space and simplifying installation, but is harder to remove for service |
|---|---|
| Lower rated KSF Series units | The 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 ball | This 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 |
