Bervina produces single piece construction helical beam couplings with zero backlash and constant velocity that compensates for angular, parallel and axial misalignments during operation.
Beam coupling has a very high torsional stiffness that makes it appropriate for motion control applications, where extremely accurate positioning, frequent stop and goes and reverse rotation are required. Couplings are available in stainless steel and aluminum with metric, inch and inch to metric bore sizes with H7 tolerance.
There are single (three beam) and multi (six) beam couplings available with set screw or clamping attachment styles. Single beam couplings have a shorter length allowing us to build in existing equipment with all the best attributes of a helical coupling.
