Elastomer Coupling Model EK 7
with expanding shaft from 2 - 2,150 Nm

	axial hub mounting with
	expanding shaft
	very smooth running
	high clamping forces

Design:
Two coupling hubs are concentrically machined with concave driving jaws.
One side with clamping hub and a radial screw ISO 4762.
One side with an expanding shaft and tapered clamping element Suggested
bore tolerance for the driven shaft: H7.

Temperature range:
The temperature range depends on the choosen Elastomer insert.

Backlash:
Absolutely backlash-free.

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

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

Material:
Clamping hub: high strength aluminium.
Expanding shaft & cone: steel.
Elastomer insert: precision molded wear resistant and
thermally stable polymer.

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

Technical Data:

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

Properties of Elastomer Coupling Model EK 7:

	short compact design, conserves space while reducing costs
	easy mounting
	high concentricity
	axial mounting of the expanding shaft
	backlash free
	electrical insulating

This Elastomer Coupling is available as ATEX version
for applications in explosive atmosphere.
