This document contains specifications for various planetary gearhead models including size, ratios, backlash, torque ratings, efficiency, weight, inertia, bearing life, and contact information for the manufacturer Electromate. Single and double stage gearheads are listed with maximum continuous torque ratings provided for different input speeds. A chart also shows the expected bearing life in hours for various radial and axial load combinations on the output shaft ranging from 5,000 to 200,000 rpm.

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.
