Key Benefits
- Rated for 120 kg working load and 150 kg maximum load per unit
- Press mount design allows for fast installation into a pre-drilled 70 mm hole
- 25.4 mm diameter ball provides stable rolling under heavy flat loads
- Steel or stainless steel case options suit dry, wet or washdown environments
- Nylon ball option protects painted or polished surfaces from marking
Application Scenarios
- Transfer points in a flat deck conveyor system where trays or pallets need to be redirected
- Assembly line stations where a heavy flat component must be repositioned by hand
- Feeding systems for packaging machinery requiring smooth omnidirectional movement
- Processing tables where a flat sheet or panel is rotated or aligned manually
- Curved work areas on router tables or band saws where directional control is needed
Who It Is For
- Conveyor system integrators building high load transfer points
- Material handling equipment builders designing flat deck transfer zones
- Industrial distributors stocking ball transfer units by load and mounting type
- Assembly line builders needing reliable manual repositioning points
Problems It Solves
- Heavy flat loads that stick or jam when pushed across a fixed deck plate
- Transfer points where product must change direction without powered diverters
- Manual repositioning of flat components that require precise alignment
- Need for a single consistent range of high load ball transfer units instead of multiple suppliers
- Lack of durable press mount units that match existing deck hole sizes
Technical Features
- 25.4 mm diameter steel ball for high load stability and consistent rolling
- Press mount design with a 70 mm diameter outer ring for insertion into a deck hole
- Steel ball and case standard, with stainless steel case option for corrosive areas
- Nylon ball option available to prevent surface marking on delicate materials
- Unit weight of 900 g for deck load and shipping planning
Materials
- Carbon steel ball and case for general industrial use
- Galvanized steel case for moderate corrosion resistance
- Chrome plated steel case for improved wear and appearance
- Stainless steel case for wet, washdown or corrosive environments
- Nylon ball for non-marking contact with painted or polished surfaces
Quality Control
- Load capacity verified against the 120 kg working load rating
- Ball rotation tested by hand to ensure free movement in all directions
- Material grade confirmed against the case and ball option ordered
- Press fit diameter checked to ensure 70 mm outer ring fits standard deck holes
Customization Options
- Ball material selected between steel and nylon
- Case material selected between steel, galvanized steel, chrome plated steel and stainless steel
- Other IS Series load ratings available where 120 kg is not the right size
Use Guide
- Ensure the deck plate has a 70 mm diameter hole for press fit installation
- Divide the total load by the number of units in contact to stay within the 120 kg per unit rating
- Keep peak and impact loading below the 150 kg maximum load figure
- Choose nylon ball where the load surface must not be marked
- Choose stainless steel case where the deck is exposed to moisture or cleaning agents

Compared With Other Options
| Flange mount ball transfer units | Press mount units install faster into a deck hole but are harder to remove for service compared to flange mount units |
|---|---|
| Lower rated IS Series units | The IS-25 suits 120 kg loads, so lighter decks are better served by a smaller unit that rolls with less effort |
| Plain conveyor rollers | Ball transfer units allow movement in any direction, while rollers only move product along one axis |
