Product details

The BULLFLEX couplings are specifically designed for even better vibration damping. Thanks to their super elastic rubber shock absorbers (prestressed) and a special centering ring very smooth running is acheived. Even at low engine speeds. The BULLFLEX coupling can compensate for up to 2° misalignment. With a built-in thrust bearing, axial vibrations and shocks are effectively damped and kept away from the drive system. The performance figures are based on DIN A performance per 100 shaft rev / min Available in different versions.

The BULLFLEX coupling type 4 has a 4 inch bolt circle, type 8 has a 4 inch and 5 inch bolt circle. Thus, the BULLFLEX can be mounted directly to most gear types including Hurth, Velvet, TD, ZF and Paragon. These couplings do not work with V drives.

Bullflex type 4 - Load capacity (max. motor power): 2.8 HP per 100 rpm on the shaft
Bullflex type 8 - Load capacity (max. motor power): 5.8 HP per 100 rpm on the shaft

The Bullflex is nice and good, unfortunately the holes do not match my Mirth gearbox MS15A.

Flag of English Hi, I don't have flexible coupling yet, but hard connection between transmission and shaft. Both are Aligned. I wanna reduce vibration to the boat. Do you think that this could help? And how much? My engine mounts are new, so only way is this thing. Is it worthwhile for the price? Thanks for advices

The BULFLEX coupling will certainly reduce vibrations when installed. Unfortunately, we cannot make any statement about the size of the reduction because every motor and shaft installation is different. In addition to pure damping, the coupling is also able to compensate for angular deviations, absorb thrust forces in the axial direction and provides electrical isolation.

Flag of English Hello, Does it have an adapter flange2 as a part of a unit or it should be purchased separately?

The adapter flange FLANGE2 is not part of the coupling and must be ordered separately.
