Spring Loaded Press Mount Ball Transfer Unit KSF-19H
The KSF-19H is a spring loaded press mount ball transfer unit with a 19.05 mm diameter steel ball, rated for 50 kg working load and 70 kg maximum load. It is designed to be pressed into a 36 mm diameter hole in a deck plate, allowing flat, smooth objects like trays to be moved and rotated in any direction by hand. The unit weighs 350 g and is available with a steel, galvanized steel, chrome plated steel or stainless steel case.
Product Overview
The KSF-19H is a spring loaded press mount ball transfer unit with a 19.05 mm diameter steel ball, rated for 50 kg working load and 70 kg maximum load. It is designed to be pressed into a 36 mm diameter hole in a deck plate, allowing flat, smooth objects like trays to be moved and rotated in any direction by hand.

Part of the KS KSM Series range, used in Warehouse and Distribution Centres.
Key Benefits
- Carries 50 kg per unit in normal service and 70 kg at peak load
- Spring loaded design maintains consistent ball contact under load and compensates for minor deck surface variations
- Press mount fits into a 36 mm hole so no flange or bolts are needed
- Steel ball and case options suit general industrial environments
- Stainless steel case option for wet or corrosive areas
Application Scenarios
- Transfer points on a flat deck where trays or flat panels are repositioned by hand
- Feeding systems on packaging or processing machinery where product alignment is needed
- Curved work areas on router tables or band saws requiring 360 degree movement
- Assembly line stations where a fixture must be rotated without powered assistance
- Conveyor end points where a flat load needs to be turned before entering the next line
Who It Is For
- Conveyor system integrators building low load transfer points
- Material handling equipment builders designing manual repositioning stations
- Packaging and processing machinery manufacturers needing omni-directional movement
- Industrial distributors stocking ball transfer units by load and mounting type
- Production line builders requiring simple, low maintenance transfer points
Problems It Solves
- Flat loads that jam or drag when pushed across a fixed deck plate
- Transfer points where product must change direction without powered diverters
- Decks with slight warping or unevenness that cause ball transfer units to bind
- Need for a compact, low-profile transfer unit that does not require bolt holes
- Manual repositioning tasks where a powered solution is not cost effective
Technical Features
- Spring loaded mechanism maintains ball contact under load
- 19.05 mm diameter steel ball for consistent rolling performance
- Press fit into a 36 mm diameter hole with no bolts or flange required
- Housing made from carbon steel, galvanized steel, chrome plated steel or stainless steel
- Unit weight of 350 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 moderate environments
- Chrome plated steel case for a smoother surface and better wear resistance
- Stainless steel case (SUS304) for wet, washdown or corrosive areas
Quality Control
- Load capacity verified against the 50 kg rating before packing
- Ball rotation checked by hand for free movement in all directions
- Material grade confirmed against the case option ordered
- Spring tension checked to ensure consistent ball contact under load
Customization Options
- Case material selected between carbon steel, galvanized steel, chrome plated steel and stainless steel
- Ball material is steel, not available in nylon or stainless steel
- Other KSF Series load ratings available where 50 kg is not the right size
Use Guide
- Ensure the deck plate has a 36 mm diameter hole for press fit installation
- Divide the total load by the number of units in contact to stay within the 50 kg per unit rating
- Keep peak and impact loading below the 70 kg maximum load figure
- Use the stainless steel case where the deck is exposed to moisture or cleaning agents
- Do not use on uneven or soft bottom surfaces such as cloth-wrapped items

Step 2
Spring and ball assembly with preload adjustment
Step 3
Finishing of the case surface (galvanizing, chrome plating or polishing)
Step 4
Load check and final inspection before packing
Compared With Other Options
| Flange mount ball transfer units | Press mount requires no bolts or flange, so installation is faster but harder to remove for service |
|---|---|
| Lower rated KSF Series units | The KSF-19H suits 50 kg loads, so lighter applications are better served by a smaller unit with less rolling resistance |
| Spring loaded press mount units with nylon balls | The KSF-19H uses a steel ball, so it is not suitable for surfaces that must not be marked |
