Sizing a replacement for a 60 mm planetary drive
The GBX0600161002F is a 60 mm diameter planetary gearbox with straight-cut teeth and a 16:1 reduction ratio — a common size for servo-driven indexing tables, conveyor transfer stations, and pick-and-place axes where the motor flange and load interface are already machined for this frame. Continuous output torque is 44 N.m at 100 rpm, with a maximum intermittent torque of 70 N.m — the 16:1 ratio multiplies motor torque by roughly that factor, minus the 94 % efficiency loss, so the motor-side torque at rated load is about 2.9 N.m continuous. Torsional backlash is 20 arcmin maximum — this is a commercial-grade positioning budget, not a zero-backlash unit; for applications needing tighter repeatability, a preloaded or dual-drive arrangement would be needed.
Obsolete — sourcing a legacy gearbox
For a line-down situation or a BOM that already has the mounting interface machined, the only channel is independent surplus or new-old-stock inventory — quantities are lot-specific and confirmed at RFQ, not from the factory. The 60 mm housing diameter, 16:1 ratio, and 44 N.m continuous rating are the three dimensions that must match for a drop-in swap; any replacement from another manufacturer will need the input flange, output shaft keyway, and pilot diameter verified against the existing motor and load adapter.
Load ratings and service life at 100 rpm
Rated service life is 30,000 hours at 100 rpm and 30 °C ambient — that is about 3.4 years of continuous 24/7 operation at that speed and temperature. Maximum radial force on the output shaft is 340 N at mid-span for the full 30,000-hour life, or 500 N if you accept a shorter 10,000-hour life — overhung loads from belt drives or pinions need to stay within these limits to avoid bearing fatigue. Maximum axial force is 450 N for the 30,000-hour target, 600 N for 10,000 hours — thrust loads from helical gears or leadscrew drives must be checked against these figures.
Environmental and mechanical construction
The housing is black anodized aluminium, 60 mm diameter, with the shaft output sealed to IP54 — splash-resistant but not submersible, so locate it away from washdown spray if possible. Shaft material is C45 carbon steel, and the gearbox is lubricated for life — no maintenance ports or regreasing schedule, which simplifies installation but means the unit is sealed and cannot be serviced if the lubricant degrades.
