Stober P521SPR0030MT ServoFit Precision Gearhead

Stober's ServoFit P521SPR0030MT inline precision planetary gearhead delivers a 3.0:1 reduction in a compact, single-stage package (size 2) designed for direct servomotor integration. The MT variant includes a ServoCool motor plate with TriAdapt coupling, enabling straightforward motor mounting and reliable torque transmission. The unit features an output shaft with a key and a metric interface (M12x28), facilitating secure attachments to driven components. As part of the ServoFit P-series, it uses normal bearings (R option) and is engineered for high-precision positioning in constrained spaces. With a 3:1 ratio, the gearhead provides increased output torque while preserving a compact footprint, making it well suited for servo-driven axes in automation, robotics, CNC, and packaging applications where space is at a premium. The inline configuration and standardized mounting pattern across the P521/P522 family help ensure compatibility with STOBER servo motors and ready integration into existing drive systems.
