Miki Pulley announces Step-Flex Coupling available for direct sale to NA OEMs

Miki Pulley Step-Flex

With this construction, the hard (black) element is separated from the aluminum alloy hubs by a softer (green) elastomer. This maintains enough torsional stiffness for precise positional accuracy while still allowing for minimal angular and parallel misalignment, and absorbing vibration.

The Step-Flex is a new class of shaft coupling. This design was conceived to eliminate resonance in stepper motor ball screw assemblies. The innovative two part elastomer element combination dampens vibration caused by the actuator carrier struggling to find its home position by making small adjustments in rapid sequence.

The power-transmitting element, consisting of different hardness layers also achieves a reduction in counter force generated by misalignment. This can greatly reduce the load on the bearing – resulting in reduced heat load.

  • 5 sizes available
  • Torque: 53 in-lbs. (6 Nm)
  • Bore size range: 1/8” to 5/8” (3mm – 16mm)

Step-Flex applications include automation of all types where ball screws are used including packaging, semi-conductor assembly, laboratory automation and medical equipment.
