R+W BKL Series Metal Bellows Coupling
The R+W BKL series metal bellows coupling is a market-leading, high-precision solution providing near-zero backlash, excellent axial and angular compensation, and superior fatigue life under high-speed, high-temperature, and high-torque conditions—positioning it as the top technical choice for demanding flexible coupling and torque damper applications. Although it commands a premium compared with elastomeric models (Lovejoy, TB Wood's) and some clamp bellows (Ruland), its higher upfront cost is often justified by lower lifecycle risk, better torsional stiffness, and greater reliability in critical servo and industrial drives.
