The STM Helical Inline Gearboxes AMP from HMA Flow & Industrial are based on a single-body casting for increased rigidity. This allows for the application of high loads without any risk of deformation that might impact the technical performance negatively. The particular internal shape of the body directs the oil flow in a such way that it reaches all moving parts, while reducing noise levels and improving sealing tightness. Another feature is the modular output flange, which allows for a great versatility of application.
