Hydraulic rings and propeller nuts SKF

Hydraulic rings and propeller nuts

Traditionally, ship propellers are mounted on a tapered shaft end with a nut and key. The torque is transmitted through friction of the mating surfaces and the key performs a stand-by function if the friction is insufficient.

Roller screws SKF

Roller screws

Roller screws offer a performance level far beyond the capabilities of ball screws. They are well suited for heavy loads, high duty, high rotational speed, high linear speed, high acceleration (especially planetary roller screws), ultimate precision and rigidity, and for operation in harsh environments.
