Alpha BC2 Series

Alpha BC2 - Bellows Coupling

Bellows couplings for direct drives.

  • Material: Bellows made of highly flexible stainless steel.
  • Design: With clamping hubs and a single lateral screw to ISO 4762. Any imbalance of the clamping hubs due to the design is compensated by balancing bores located on the hub interior.
  • Temperature range: -30 to +120°C (-22 to 248 °F)
  • Backlash: Completely backlash-free as a result of the frictional clamp connection.
  • Service life: These torque limiters are permanent and maintenance-free as long as the performance limits are not exceeded.
  • Fit tolerance: Tolerance between shaft and hub 0.01 – 0.05 mm
  • Speeds: Up to 10,000 rpm / in excess of 10,000 rpm with finely balanced version.
  • Brief overload: Acceptable up to 1.5 times the value specified.
