ST4 | Torque Limiting Coupling

For Direct Drives

The ST4 Mounts with a key-way or spline connection. An integral gear coupling provides axial, lateral, and angular misalignment compensation. Gear coupling ends feature extremely wear resistant tooth geometry made from high-strength alloyed steel.
Field adjustable torque modules are evenly spaced around the circumference, delivering high torque density and precise overload protection. The torque limiter is made from High-strength, nitro-carburized steel.
It has a rated operating temperature range of -30 to 120 °C (-22 to 248 °F) and standard balancing is G16, (higher speeds upon request).
This is a robust coupling with an infinite, maintenance free service life when operated within the technical specifications.
