Safety Coupling / Torque Limiter Model ES2
with clamping hub from 2 - 900 Nm

  • reliable torque overload protection
  • backlash free due to
    patented R+W design
  • easy to mount

Design:
Our zero backlash elastomer coupling corporated with our torque limter.

Temperature range:
The temperature range is dependent on the choosen Elastomer insert.

Torsional stiffness:
Depends on the Elastomer insert.

Backlash:
Absolutely backlash-free.

Material:
Torque limiter: high strength hardened steel with
rust protected surface (oxidized)
Clamping hub D1: up to series 450 high strength
aluminum, from series 800 and up steel
Clamping hub D2: up to series 60 high strength
aluminum, from serie 150 and up steel
Elastomer insert: precision molded, wear resistant,
and thermally stable polymer

Fit tolerance:
On the hub/shaft connection 0.01 to 0.05 mm.

Service life:
R+W Torque limiters are maintenance-free and have an infinite life, if the tolerances are not exceeded.

Non-standard application:
Custom designs available upon request.

Technical Data:

  • rated torque from 2 - 900 Nm
  • shaft diameter from 5 - 80 mm
