Benefits

Why choose the SWS?

The SWS brings the robustness of steel to the precision of flexible elastic shafts.

01 / ADVANTAGE

Higher torque

Steel offers torque transmission capacity significantly higher than aluminium. Suited to high-torque industrial transmissions where precision remains critical.

02 / ADVANTAGE

Robustness

Steel tolerates shocks, overloads and severe conditions. Maximum service life in demanding industrial environments.

03 / ADVANTAGE

Durability

No sensitive elastomer element. Compensation is done by elastic deformation of the steel body — a mechanism that does not wear under normal operating conditions.

Product description

The SWS flexible elastic steel shaft brings the industrial robustness of steel to the design of machined-body elastic shafts. The SWS offers torque transmission capacity significantly higher than the aluminium version (SWA), while retaining the angular precision and zero torsional backlash characteristic of this family.

The compensation of misalignment (parallel, angular, axial) is carried out by controlled flexion of the steel body, without resorting to an elastomer element sensitive to ageing.

The SWS is suited to high-torque industrial transmissions where precision remains critical: cutting machines, production lines with angular sensors, transmissions on high-power servomotors. Its service life is maximum under normal operating conditions.

Machined steel body — torque capacity superior to aluminium
Compensation by controlled flexion of the body
Industrial robustness — tolerates shocks and overloads
High angular precision — no torsional backlash
Maximum durability, long service life
No elastomer — no material ageing
