MaxTorque, LLC reserves the right to modify or update technical data at any time based on on-going testing and field experience.
Efficiencies are based on dynamic performance after a reasonable break-in period.
Self-locking characteristics are similar to those of other self-locking worm gearboxes. Specific environmental conditions such as high vibration may adversely affect self-locking characteristics. If locking is required in this or other conditions, a separate brake should be utilized.
