ST2 | Torque Limiting Coupling

For Direct Drives

The ST2 Mounts axially with a key-way or spline connection. Precision molded elastomer segments provide axial, lateral, and angular misalignment compensation. They are made from a vibration damping, wear resistant rubber compound (75-80 Shore A).
Field adjustable torque modules are evenly spaced around the circumference, delivering precise overload protection. Coupling hubs are made from high-strength cast steel (coated) while the torque limiter is High-strength, nitro-carburized steel.
Standard balancing is G16, (higher speeds upon request).
This coupling has an infinite, maintenance free service life when operated within the technical specifications.
