Product Description
The R+W BK2 torsionally stiff bellows coupling is a high-performance precision coupling designed to deliver backlash-free torque transmission while compensating for angular, radial and axial shaft misalignment. Featuring a robust metal bellows and clamp hub design, the BK2 provides exceptional torsional rigidity, high accuracy and reliable operation in demanding servo drive, automation, robotics and motion control applications. Its compact construction, low inertia and maintenance-free design make it ideal for systems requiring precise positioning, repeatability and smooth power transmission at high speeds.
