Stromag VN 350 11 G Periflex Coupling | Elastomeric Industrial Drive Coupler

The VN 350 11 G is part of the Stromag Periflex VN series of torsionally flexible couplings engineered for demanding industrial environments. Periflex couplings are widely used in compressor packages, generator sets, pump drives, and heavy machinery where drivetrain protection and vibration control are critical.

The VN series utilizes a high-strength elastomer element mounted between precision-machined hubs. This design allows torque to be transmitted smoothly while absorbing torsional shock loads generated during startup, shutdown, and load fluctuations.

The VN 350 11 G configuration is designed for high reliability, predictable torsional behavior, and long service life in continuous-duty applications.

Functional Design and Engineering Advantages

The VN 350 11 G coupling incorporates a durable elastomer ring positioned between robust metal hubs. Torque is transmitted through the elastomer element in compression, reducing metal-to-metal contact and minimizing vibration transfer.

This design provides several operational advantages:

• Reduced torsional peak loads

• Lower mechanical noise

• Improved drivetrain smoothness

• Extended bearing and shaft life

• Reduced maintenance frequency

In compressor and engine-driven applications, torsional pulses can cause long-term drivetrain fatigue. The Periflex elastomer compound is engineered to provide consistent flexibility while maintaining structural integrity under sustained load conditions.

Because Stromag designs Periflex couplings for industrial service, the VN 350 11 G delivers stable torque transmission and reliable vibration isolation in challenging operating environments.
