BX4 | Industrial Bellows Coupling

High Torque With Key-Way Mounting

The BX4 features steel, removable coupling hubs on both sides along with two bellows and an intermediate tube (Series 10 without intermediate tube). Bellows are made from highly flexible, high grade stainless steel with a welded connection between the hubs and bellows.
This is a simple, compact and easily mounted design that is suitable for high torque applications. It is torsionally rigid and offers a high degree of misalignment compensation.
Custom designs with various tolerances, key-ways, materials, dimensions, etc. are available upon request, for non standard applications.
*Various overall lengths available.
