This document provides specifications for planetary gearheads, including size, torque ratings, backlash, construction types, ratios, efficiencies, weights, input speeds, part numbers, and bearing life calculations for various radial loads, axial loads, and speeds. Planetary gearheads come in single-stage and double-stage models with ratio ranges from 4:1 to 100:1 and maximum input speeds of 5,000 rpm. Tables provide maximum output torques and part numbers for various gearhead ratios. Charts show the estimated bearing life in hours for combinations of radial load, axial load, and gearhead output shaft speed.

Fradial
Faxial
Speed (rpm) refers to
the gearheads output
shaft speed.
Life (hrs) = (# of lifetime
revolutions) ÷ (60 x
rpm).
Fradial
is calculated at one
half the shaft length.
