Bellows Coupling BK8

Product catalog summary

Overview: The document provides technical specifications and details for the R+W America Series BK 8 bellows couplings, designed for torque ranges from 15 to 2,600 Nm. These couplings are characterized by their reliability and torsional rigidity, making them suitable for various mechanical applications.

Specifications:

Model: BK 8
Properties: Zero backlash, high torsional rigidity, easy assembly, compact design, suitable for space-restricted installations.
Materials: Hubs made of aluminum (series 300) and steel (series 1500); bellows made of high-grade stainless steel; intermediate flange made of steel.
Design: One side features a clamping hub with a single radial clamping screw (ISO 4762); the other side has a flange connection with a separate intermediate flange.
Speed: Up to 10,000 rpm.
Temperature Range: -30 to +120°C (3.6°F to 270°F).
Fit Tolerance: 0.01 to 0.05 mm on the hub/shaft connection.
Customization: Available upon request for varied tolerances, keyways, non-standard materials, and bellows.

Dimensions and Performance:

Flange Centering Diameter: Ranges from 40 mm to 160 mm depending on the series.
Max Torque: Ranges from 50 Nm to 2,600 Nm.
Length and Diameter: Varies by series, with outer diameters ranging from 49 mm to 157 mm.
Weight and Inertia: Approximate weight ranges from 0.3 kg to 10 kg; moment of inertia ranges from 0.15 to 45 (10^-3 kgm²).
Misalignment Tolerance: Lateral up to 0.2 mm, angular up to 1 degree, axial up to 3 mm.

Installation: The document includes details on mounting and dismounting procedures, emphasizing the importance of proper alignment and secure fastening using specified screws and torque values.
