Spring Loaded Press Mount Ball Transfer Unit KSF-19B
The KSF-19B is a spring loaded press mount ball transfer unit with a 19.05 mm diameter steel ball, rated for 70 kg working load and 80 kg maximum load. It is designed to be pressed into a mounting hole in a deck plate, allowing flat, smooth objects like trays to be moved in any direction by hand. The unit weighs 260 g and is available in carbon steel, galvanized steel, chrome plated steel or stainless steel (SUS304) cases with a steel ball.
Product Overview
The KSF-19B is a spring loaded press mount ball transfer unit with a 19.05 mm diameter steel ball, rated for 70 kg working load and 80 kg maximum load. It is designed to be pressed into a mounting hole in a deck plate, allowing flat, smooth objects like trays to be moved in any direction by hand. The unit weighs 260 g and is available in carbon steel, galvanized steel, chrome plated steel or stainless steel (SUS304) cases with a steel ball.
Part of the KS KSM Series range, used in Warehouse and Distribution Centres.
Key Benefits
- 70 kg working load and 80 kg maximum load per unit for light to medium duty transfer
- Spring loaded design maintains ball contact under load and compensates for minor deck surface variations
- Press mount installation allows fast integration into deck plates with minimal tooling
- Steel ball with carbon steel, galvanized, chrome plated or stainless steel case options for different environments
- 19.05 mm diameter ball provides smooth omnidirectional movement for flat, rigid items
Application Scenarios
- Transfer points between two straight conveyor lines where product must change direction
- Feeding tables in packaging machinery where trays are manually repositioned
- Processing stations on a router table or band saw where a flat workpiece is rotated
- Assembly line workbenches requiring manual alignment of components
- Conveyor decks where a light load must be moved freely in any direction without powered guidance
Who It Is For
- Conveyor system integrators building low load transfer points
- Material handling equipment builders designing manual repositioning stations
- Packaging machinery manufacturers needing omnidirectional movement for trays
- Industrial distributors stocking ball transfer units by load and mounting type
- Production line builders integrating manual alignment points into assembly stations
Problems It Solves
- Manual repositioning of flat items that cannot be moved easily on fixed rollers
- Transfer points where product must change direction without a powered diverter
- Deck surfaces that are slightly uneven and cause ball transfer units to bind
- Need for a fast-installation mounting method without requiring bolts or flanges
- Light load applications where a full flange mount unit is unnecessary and over-engineered
Technical Features
- Spring loaded mechanism maintains consistent ball contact under load
- 19.05 mm diameter steel ball for smooth omnidirectional movement
- Press mount design with no external fasteners required after installation
- Housing made from carbon steel, galvanized steel, chrome plated steel or stainless steel (SUS304)
- Steel ball material ensures durability and consistent rolling performance
Materials
- Carbon steel case for general industrial environments
- Galvanized steel case for improved corrosion resistance in humid areas
- Chrome plated steel case for wear resistance and appearance
- Stainless steel (SUS304) case for washdown, food, or corrosive environments
- Steel ball for consistent rolling performance and load support
Quality Control
- Load capacity tested against the 70 kg working load before packing
- Ball rotation checked by hand for free movement in all directions
- Material grade confirmed against the case option ordered
- Press fit integrity verified to ensure no loose fit after installation
Customization Options
- Case material selected between carbon steel, galvanized steel, chrome plated steel and stainless steel (SUS304)
- Ball material is steel, not available in nylon or stainless steel
- Other KSF Series models available for different load ratings or mounting types
Use Guide
- Ensure the deck plate hole is clean and free of burrs before pressing in the unit
- Press the unit into the hole until the case is flush with the deck surface
- Do not exceed 80 kg maximum load to avoid permanent deformation
- Use only on flat, smooth surfaces such as trays or rigid panels
- Avoid use on soft or uneven bottom surfaces like cloth-wrapped items

Compared With Other Options
| Flange mount ball transfer units | Press mount installs faster with no external fasteners, but is harder to remove or replace after installation |
|---|---|
| Spring loaded flange mount units | Press mount is lower profile and faster to install, while flange mount allows easier service and replacement |
| Non-spring loaded units | Spring loaded units maintain ball contact on uneven decks, while non-spring units may bind or lose contact under load |
