National Style Dy-A-Flex Clutches

 

Twin Disc Company Logo

 

National Oilwell Dy-A-Flex Style Air Clutches are commonly found operating on National Draw works in the oil well drilling industry.

 

It operates in principal like the VC style clutch from Eaton Airflex, in that it was designed for heavy-duty applications and has an open construction, which allow for high heat dissipation. Its ability to handle heavy loads, while withstanding repeated engagement and disengagements has made it a dependable performer.

 

Instead of utilizing an independent enclosed air actuating tube like the VC, the Dy-A-Flex unit uses an enclosed diaphragm for clutch actuation. Every single component of the Dy-A-Flex unit is replaceable, meaning it can be rebuilt. Dy-A-Flex air clutches are available in six (6) sizes, with a variety of side plate configurations.
