Material: Hubs 11 SMn Pb 37, from Ø 55 mm CK45. Spring: Spring
steel type C. These couplings are elastic all-metal couplings and
completely maintenance free. The all-metal design leads to a strong
resistance against oil and higher temperatures: -40°C to +100°C. The
elastic part consists of a spring body, made up of three layers of wound
springs welded into the connecting hubs. The couplings are suitable for
both rotating directions. They can be locked against rotation with a
feather key or with pins. The couplings are pressfitted. Demounting is
done by pressing or pulling off. Vibrations and shocks are largely
absorbed. Depending on the length of the coupling – S, L or Db – bending
of 3 – 6° or axial displacement of 3 – 6% of the nominal shaft diametre
are possible. Couplings are available pre-drilled ex stock. Customized
bores and feather-key grooves available at surcharge.
