Elastomer Couplings EK

• very smooth running
• high clamping forces
• axially mountable
• light weight aluminum

Design:
Two coupling hubs are
concentrically machined
with concave driving jaws.

Temperature range:
The temperature range depends on the 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:
Clamping hub: high strength aluminum.
Conical clamping ring: high strength aluminum.
Elastomer ring: precision molded wear resistant,
and thermally stable polymer.

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

Non-standard application:
Custom designs with varied tolerances, keyways and non-standard material are available upon request.

Technical Data:

• rated torque from 4 - 2,150 Nm
• shaft diameter from 6 - 80 mm
