VETUS Bullflex Coupling Type-8 Shaft 1.25inch

Its pre-tensioned rubber element ensures low-noise and
vibration-free transmission, without backlash between the engine
and the propeller shaft.

Another strong point of the Bullflex coupling is the excellent
alignment; even with a misalignment of 2, the shaft will remain
perfectly centered.

ADVANTAGES OF THE VETUS BULLFLEX COUPLING:

• Very high flexibility
• Optimum damping of vibrations
• Secured against shearing off (axially and radially)
• Misalignment of up to 2 permissible
• Excellent centering of the shaft, allowing for high shaft
  revolutions, even at 2 misalignment
• The shaft will remain centered even in reverse gear
• Possibility to remove the centering ring
• Built-in thrust damper
• Non-tapered clamping hub, for perfect centering and easy
  assembly/dismantling

Which Size Bullflex Coupling do I need?
The calculation is fairly simple – to determine the HP/100 r.p.m
ratio figure the equation is:
(Engine HP x 100) / The maximum speed of the propeller shaft.
