Lifetime Series Gearheads

Features and Benefits

Lifetime zero backlash
Lifetime ultra-high repeatability (typically a few arc-sec)
Lifetime high positional accuracy (+/- 1.5 arc-min std.) (+/- 0.5 arc-min by request)
Single stage, high reduction ratios of 50:1 to 160:1
Low noise and heat generation
High efficiency, torsional stiffness and torque-to-weight ratio
High torque capacity with a large number of teeth sharing load

Stressproof® Output ShaftProvides a minimum 115,000 psi tensile strength, resistance to fatigue and excellent wearability.
Output FlangeHas a precision pilot and is available in metric, NEMA 17, 23, 34 & 42 sizes and can be factory modified to customer specifications.
Double Row Angular Contact BearingProvides a precision output with high stiffness, high radial and axial load capacities.
FlexsplineA thin walled external spline that progressively engages with the Circular Spline with a zero backlash tooth mesh.
Wave GeneratorPrecision elliptical ball bearing that turns with the input motor and causes the rotating elliptical wave form on the Flexspline.
Circular SplinePrecision shaped internal spline, remains stationary and engages the Flexspline.
Quick Connection Motor CouplingA socket head tightened clamping collar provides a reliable and simple motor connection.
Sealed BearingA precision bearing axially fixes the input shaft and wave generator positions.
Input FlangeFactory machined to match your motor dimensions and available in standard NEMA 17, 23, 34 & 42 sizes.
