The GBX0600400583D is a straight-tooth planetary gearbox with a 60 mm outer diameter and a 40:1 reduction ratio, delivering 40 N.m continuous output torque and a 70 N.m peak ceiling. At 94% efficiency, about 6% of the input power is lost as heat through the gear mesh — that's typical for a single-stage planetary at this ratio and keeps the housing within the -25 to 90 °C operating range without forced cooling. The 25 arcmin maximum torsional backlash means the output shaft can lag the input by up to 25 arcminutes before the teeth engage — fine for conveyor indexing or constant-speed drives, but a servo-grade planetary with sub-10 arcmin backlash would be needed for a reversing positioning axis. Rated service life is 30,000 hours at 100 rpm output and 30 °C ambient — that's about 3.4 years of continuous 24/7 operation before the grease degrades. The gearbox is lubricated for life, so no oil-change interval to schedule.
Mounting, loads, and sealing — what fits in the envelope
The black anodized aluminium housing mounts in any position, which simplifies integration into a vertical or inverted axis without derating. Shaft output sealing is IP54 — splash-proof from the shaft side, but the motor-mount interface and the load coupling are the user's responsibility to seal if the assembly sees washdown. Maximum axial force on the output shaft is 450 N at 100 rpm for the full 30,000-hour life, or 600 N if you accept a shorter 10,000-hour service window. Radial force at mid-shaft is 340 N for the long-life case, 500 N for the short-life case — these numbers govern bearing selection in the driven mechanism. Torsional rigidity is 2.5 N.m/arcmin — the shaft twists about 0.4 arcminutes per N.m of load, which is stiff enough for most positioning applications that don't require zero-backlash.
