AHL Precision Planetary Reducer

MANUFACTURER DOCUMENTATION

Overview

AHL is a separate Beitto inline planetary family with a different frame-code sequence from AHB. Its official catalog section lists 050, 070, 090, 120, 155 and 205 sizes. The model-code diagram gives one-stage reduction of 3 to 10 and two-stage reduction of 15 to 100. The AHL features page states standard backlash of 5 arcmin for the described grade. It also depicts helical gearing, a needle-roller-supported output arrangement and an adapter-bushing motor connection. Those catalog values narrow the choice but do not identify a torque limit for any particular frame. Request the chosen AHL size, ratio, shaft dimensions and load table for a servo-driven machine.

The source page provides a series overview rather than a complete model/ratio rating table. Use the manufacturer link above for selection drawings and confirm the precise operating point before ordering.

Before you specify this gearbox

A planetary gearbox shares load across several planet gears. Confirm nominal and peak torque separately, together with ratio, input speed, backlash and mounting dimensions.

• Confirm continuous, peak and emergency-stop load limits separately.
• Match the motor flange, shaft, mounting orientation and lubrication requirements.
• Request the current drawing revision and selection calculation from the manufacturer.
