Material: Hub 1.4305 (AISI 303). Spring: Spring steel 1.4310.
These couplings are elastic all-metal couplings and completely
maintenance free. The all-metal design leads to a strong resistance
against oil and higher temperature range: -40°C to +300°C. The elastic
part consists of a spring body, made up of three layers of wound
springs. 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.
