The 300 series of planetary gearboxes enjoy a high overhung and axial load capacity due to heavy duty tapered roller bearings, featured on the H and P versions.
High torque density and efficiency are gained through inner parts being coupled using splined connections, rather than the keyway system found on some brands. Planetary gears are mounted onto self-centering carriers, which ensures the most even load distribution among the gear sets.
