Elastomer Couplings EK

• Easy assembly
• Damps vibrations
• Reliable torque overload protection
• Zero backlash due to
  reliable R+W design

Design:
Two coupling hubs are concentrically machined with concave driving jaws. One side with an integrated torque limiter. The torque limiter is available in single position, multi position or full-disengagement versions.

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

Torsional stiffness:
Depends on the Elastomer insert.

Backlash:
Absolutely backlash-free.

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

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 series 150 and up steel
Elastomer insert: precision molded, wear resistant,
and thermally stable polymer

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
