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.
