EZ2 Heavy Duty
Elastomer couplingsThis heavy-duty R+W claw coupling of the EZ2 type with its press-fit design can be ordered up to 4 meters in length and does not require an intermediate bearing. This intermediate shaft is easy to assemble and disassemble. The concentrically machined clamp hubs and shaft provide the coupling with a very smooth runout. The entire construction ensures that the coupling is free from play, even in laterally built direction. The EZ2 coupling can be combined with various types of R+W elastomer stars. All types of R+W elastomer stars dampen vibrations and are electrically insulating. For specific inquiries about claw couplings or other industrial couplings, please contact VARIODRIVE.
