Procurement reality — obsolete, sourced per RFQ
Schneider Electric lists the GBX0600160551F as obsolete.
Torque, ratio, and backlash — the fit numbers
The 16:1 reduction ratio and 44 N.m continuous output torque at 100 rpm define the speed-torque envelope for this 60 mm frame planetary gearbox. Maximum output torque reaches 70 N.m under the same conditions. Maximum torsional backlash is 20 arc.min — a standard-precision class for indexing and positioning axes where sub-arcmin repeatability is not required. The torsional rigidity of 2.5 N.m/arcmin gives the stiffness budget for calculating windup under load.
Load capacity and service life
Rated service life is 30,000 hours at 100 rpm and 30 °C. The gearbox is lubricated for life — no maintenance oil changes, which suits sealed-in-place conveyor drives and indexing tables where access is tight. Maximum axial force on the output shaft is 450 N for the 30,000-hour life target, stepping up to 600 N if the application accepts a 10,000-hour service window. Maximum radial force is 340 N at mid-shaft for 30,000 hours, 500 N for 10,000 hours. These derating curves let a designer trade load for life without oversizing the frame.
Environmental and mechanical constraints
The shaft output carries an IP54 rating — protected against dust ingress and splashing water, but not submersion or high-pressure washdown. Operating ambient range is -25 to 90 °C, covering most indoor industrial environments and unheated enclosures. Housing is black anodized aluminium, shaft material is C45 steel. Noise level at 1 m, no-load, is 58 dB — comparable to a quiet office, not a whining gear train that would require acoustic enclosures in a production area. Efficiency is 94 % — typical for a single-stage planetary with straight teeth at this ratio. The 6 % loss is mostly gear mesh friction and bearing drag; thermal rise is modest at continuous rated torque.
