Couplers

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
