Mechanical Shaft

The mechanical shaft uses the unique air-down gripping system & combines concentric expansion efficiency with the convenience of air retraction. It has an automatic handle instead of the ball bearings. When the shaft is vented onto machines, lugs grip the core automatically & collapse when air is added into it.

Proper concentric expansion for high–speed and heavyweight winding applications. Mechanical fail-safe operation and positive lug retraction.

• Applicable in vacuum room or high-temperature environment
• Designed for high-speed applications with high strength
• Great tension and bearing capacity for heavy-duty.
• High centering precision
• Independent lug action accommodates core variations
• The mechanical operation for most substantial grip.
• No compressed air is required.
• Easy to maneuver for complete expansion and retraction.
• Rubber key, aluminum key, or steel key is available for the lug element.
• Diameter: 1″ ~ 12″(25mm ~ 300 mm)
• Shaft material: Aluminum alloy or first-grade seamless steel with chrome-plated surface
