Part of the CY Series range, used in Sheet Metal and Press Shops.
Key Benefits
- Carries 40 kg per unit in normal service and 50 kg at peak load
- Flange mount allows secure attachment and easy removal for maintenance
- 30 mm diameter ball provides stable support for medium-weight flat items
- Available with steel, stainless steel or nylon ball to match surface requirements
- Case options in steel with galvanizing, chrome plating or stainless steel for durability
Application Scenarios
- Transfer points between two conveyor lines running at right angles
- Assembly stations where a tray or flat component needs to be rotated by hand
- Feeding systems for packaging machinery requiring smooth directional change
- Processing tables where flat parts are repositioned without powered movement
- Material handling decks in production lines where manual alignment is needed
Who It Is For
- Conveyor system integrators building transfer and rotation points
- Industrial equipment builders designing feeding or processing tables
- Packaging machinery manufacturers needing omni-directional movement
- Production line builders integrating manual repositioning stations
- Industrial distributors stocking ball transfer units by load rating
Problems It Solves
- Flat items that jam or drag when pushed across a fixed deck plate
- Transfer points where product must change direction without powered diverters
- Manual repositioning of trays or components that require 360-degree rotation
- Need for a consistent component range that matches tube diameter and shaft size
- Lack of a single supplier for ball transfer units with matching load and mounting specs
Technical Features
- Pressed ball transfer unit with flange mount for bolt-on installation
- 30 mm diameter main ball for stable support of medium-weight flat loads
- Flange with two mounting holes spaced 70 mm apart for secure attachment
- Mounting hole diameter of 7 mm to accept standard bolts
- Compact dimensions of 86 x 40 mm for integration into tight deck spaces
Materials
- Steel ball and case for general industrial use with good wear resistance
- Stainless steel ball and case for wet, washdown or corrosive environments
- Nylon ball for non-marking contact with painted or polished surfaces
- Galvanized steel case for improved rust resistance in dry or mildly humid areas
- Chrome plated steel case for enhanced surface hardness and appearance
Quality Control
- Load capacity verified against the 40 kg working load rating before packing
- Ball rotation checked by hand for free movement in all directions
- Material grade confirmed against the ball and case option ordered
- Mounting hole size and spacing verified to match 7 mm and 70 mm specifications
- Flange flatness checked to ensure even contact with the deck plate
Customization Options
- Ball material selected between steel, stainless steel and nylon
- Case material selected between steel with galvanizing, chrome plating or stainless steel
- Other CY Series load ratings available where 40 kg is not the right size
- Mounting hole size and distance can be adjusted for different deck designs
Use Guide
- Divide the total load by the number of units in contact to ensure no more than 40 kg per unit
- Keep peak and impact loading below the 50 kg maximum load figure
- Mount units on a flat, rigid deck plate so all balls sit at the same height
- Choose nylon ball where the load surface must not be marked
- Choose stainless steel ball and case where the deck is exposed to moisture or washdown

Compared With Other Options
| Press fit ball transfer units | Flange mount allows removal and replacement without damaging the deck, while a press fit unit is faster to install but harder to service |
|---|---|
| Lower rated CY Series units | The CY-30A suits 40 kg loads, so lighter applications are better served by a smaller unit that rolls with less effort |
| Swivel casters | Ball transfer units allow 360-degree movement on a flat surface, while casters are designed for floor movement and have directional limitations |
Flange Mount Ball Transfer Unit CY-30A Questions
What load can one CY-30A ball transfer unit carry?
The rated load capacity is 40 kg per unit and the maximum load capacity is 50 kg.
How is the CY-30A mounted?
It is a flange mount unit, so it is bolted through the flange onto the deck plate using two 7 mm mounting holes spaced 70 mm apart.
Which ball material should I choose?
Steel for general use, stainless steel for wet or corrosive environments, and nylon to protect painted or polished surfaces from marking.
Is a stainless steel version available?
Yes, both the ball and the case can be supplied in stainless steel.
How much does the unit weigh?
Each CY-30A weighs 240 g, which is used for deck load and shipping calculations.
Can I get other load ratings in the same series?
Yes, the CY Series includes other load ratings, so ask for the model that matches your load per unit.
