R+W elastomer couplings EK2

With clamping shaft sleeve

Specifications: 6-2150Nm

High coaxiality

Zero back gap

Easy to install


Structure: two coupling sleeves with concave claws and high concentricity.

Temperature range: depends on the quincunx elastic ring selected.

Torsional rigidity: quincunx elastic rings with different shore hardness are provided for the optimization of transmission system.

Fit clearance: shaft sleeve connection 0.01 - 0.05 mm.

Material Science:

Coupling sleeves: high strength aluminum from series to 450 and steel from Series 800

Elastic ring: made of precision molded, extremely wear-resistant and heat-resistant plastic material

Speed: see table for standard. When the speed exceeds 10000 rpm, the coupling must use fine dynamic balance (please specify).

Technical parameters: Rated torque: 6 - 2.150 Nm
