Elastomer coupling Juboflex® type S

motorfor machine toolspump

Product overview
Reinforced elastic couplings designed for medium torque transmission, combining flexibility with high resistance to torsional peaks.

Flexible element

• Precompressed natural rubber
• Bonded metal reinforcing mountings
• Precompression band (to be removed after installation)

Flange

• Die‑cast steel (except reference 632267 which is cast iron)

Advantages

• Greater load capacity compared with standard Juboflex
• Effective attenuation of cyclic irregularities and torque peaks
• Precompression improves resistance to torsional shocks
• Tolerant to significant misalignment, reducing the need for precise machine alignment

Specifications
The Juboflex® type S design provides the following functional features:

• Radial disassembly without moving the coupled machines
• Precompression of the elastic element during assembly to limit tensile stress on the rubber
