60 mm planetary gearbox — 8:1 reduction, 18 N.m continuous
The GBX0600081401F is a 60 mm diameter planetary gearbox with straight teeth and an 8:1 reduction ratio. It delivers 18 N.m continuous output torque at 100 rpm, with a maximum of 29 N.m for peak loads. Rated for 30000 hours of service life at rated load and speed, and lubricated for life — no scheduled re-greasing in the application window.
Torque, backlash, and load limits
Continuous torque is 18 N.m at 100 rpm and 30 °C; maximum output torque reaches 29 N.m under the same conditions. The 16 arcmin maximum torsional backlash suits indexing or positioning where a servo-grade zero-backlash unit is not required. Maximum axial force on the output shaft is 450 N for the 30000-hour life target, or 600 N if the application accepts a 10000-hour life. Radial force limits are 340 N (30000 h) and 500 N (10000 h), measured at mid-span on the output shaft. Torsional rigidity is 2.3 N.m/arcmin — the gearbox twists about 0.43 arcmin per N.m of applied torque, which matters for load-sharing in multi-drive setups.
Efficiency, noise, and environmental ratings
94 % efficiency means about 6 % of the input power is lost as heat — low enough that the anodized aluminium housing (60 mm diameter) dissipates it without a fan in most duty cycles. Noise level is 58 dB at 1 m, no-load — quiet enough for packaging, lab, or light assembly lines where operator exposure matters.
