Category: CF Flexible Coupling

Flexible couplings
Maximum compression for flexible couplings is typically 20% of the convolution (flexible) length. Extension is typically 10%. Flexible couplings are available in 321 or 316L material. Generally speaking, when comparing Flexible Couplings to Bellows, they are thinner walled, have more convolutions per inch resulting in greater flexibility and stroke, and are used for alignment or vibration isolation rather than as roughing lines.
