Tired of clunky couplings that limit motion and torque? The SMC-344-.500-.375 bellows coupling is the smooth, flexible solution you've been searching for.

With its flexible bellows design, the SMC-344 provides smooth, bind-free motion even when shafts are slightly misaligned. The nickel alloy bellows smoothly compresses and extends to absorb vibration, shock loads, and end thrusts. This protects connected equipment from damage while maintaining a tight seal. The stainless steel end fittings withstand corrosion for lasting performance in harsh environments.

The SMC-344 is ideal for engineers seeking to improve equipment reliability and uptime. Its flexible design protects against shaft misalignment damage for reduced maintenance. Vibration dampening ensures smoother operation and less wear on components. The corrosion resistant construction allows use in wet, outdoor, chemical and washdown applications. Quick installation lets operators service machines faster. With its high torque capacity, the SMC-344 keeps equipment performing at peak output.
