ROLLFLEX series couplings MB/J, have been designed and manufactured to connect the output shaft of a gearbox with the rope drum of hoisting equipments.
Roller couplings series MB/J comprise only a small number of components in order to guarantee easy assembly and maintenance.
Hardened steel barrel rollers are in the coupling to compensate misalignement between hub and sleeve. Roller seats are precision machined and hardened, in order to minimize wear.
These features are designed to achieve a high torsional stiffness, high torque and radial load ratings and to compensate for substantial misalignement between gearbox and rope drum.
