Vetus Flexible Vibration Damping Coupling 40mm Shaft, Marine Drive, Optimal Driving Comfort

Type Bullflex flexible coupling

Optimal damping of vibrations

The Bullflex coupling is VETUS's response to the growing demand for even greater cruising comfort. The Bullflex was specifically developed for optimal vibration damping. Torsional vibrations – which occur when the load changes and/or are the result of an unevenly running engine (especially at low rpm) – are dampened particularly effectively thanks to the super-elastic rubber element. This pre-tensioned rubber element ensures a backlash-free (= silent) and vibration-damping connection between the engine and propeller shaft. Thanks to the puncture protection (axial and radial), this connection remains optimally secured.

Advantages

• Very high flexibility
• Optimal vibration damping
• Puncture-proof (axial and radial)
• Deviation of 2º permitted
• Very good centering of the shaft, thus high speeds possible (even with 2º deviation)
• The shaft remains centered even when reversing
• Removing the centering ring is possible
• Built-in dynamic pressure bearing No conical clamping hub, for perfect centering and easy (dis)assembly

Specifications

• Models 1, 2 and 4 have a 4 "connection
• Models 8, 12 and 16 have a 4 and 5 “connection
• The model 32 has 6 threaded M16 holes on a pitch diameter of Ø 120.65 mm / 4.7" for mounting the clutches on most gearboxes (Hurth, Velvet, TD, ZF and PRM)
• VETUS also supplies the necessary mounting hardware for attaching the Bullflex to the gearbox. This coupling is not suitable for V-drives.
