Aluminum Parallel Coupling

Bervina produce single piece construction backlash free aluminum parallel couplings in three sizes to serve your motion control needs. Parallel couplings accomodate large parallel misalignment and work with high torque capacity.

The parallel 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 is required.

Couplings are available only in aluminum with metric, inch and inch to metric bore sizes with H7 tolerance.

Couplings are for applications such as shaft encoders, resolvers, step motors, all form servo devices, linear and ball screw actuators, robots, positioning tables, computers and radar.
