Planetary gearbox, 80 mm frame, 5:1 reduction
The GBX0800051402F is a straight-tooth planetary gearbox from the Schneider Electric GBX series, with an 80 mm housing diameter and a 5:1 reduction ratio. Continuous output torque is 110 N.m at 100 rpm, with a maximum peak of 176 N.m — the margin above continuous covers acceleration and intermittent overloads without oversizing the frame. Rated service life is 30,000 hours at rated load and 30 °C ambient, with the gearbox lubricated for life — no scheduled oil changes, which simplifies maintenance on a conveyor or indexing drive.
Load ratings and mechanical limits
Maximum axial force on the output shaft is 1200 N for a 10,000-hour life, derated to 900 N for the full 30,000-hour service interval — the bearing selection drives this trade-off, not the gear teeth. Maximum radial force is 650 N at mid-span on the output shaft for 30,000 hours, rising to 950 N if the application accepts a 10,000-hour replacement cycle. Torsional rigidity is 6 N.m/arcmin — the shaft wind-up under load stays under 1 arcmin per 6 N.m of transmitted torque, which matters for positioning accuracy in a servo-feed axis. Maximum torsional backlash is 9 arcmin, a standard-precision grade for the GBX series — acceptable for general motion control but not for a zero-backlash cam-indexing station.
Environmental sealing and temperature range
Shaft output sealing is IP54 — the gearbox resists dust ingress and splashing water at the output seal, but the motor adapter and housing body are not rated for washdown; mount it inside a cabinet or under a drip shield. Operating ambient temperature spans -25 °C to 90 °C, covering most indoor industrial environments and unheated warehouse spaces. Housing is black anodized aluminium — the anodized layer provides corrosion resistance in humid or mildly aggressive atmospheres, but the shaft material is C45 carbon steel, which needs a rust-preventive coating if the gearbox sits in a wet environment.
Sourcing and lifecycle — obsolete, quoted to order
Available through independent surplus and broker channels; quantities are lot-specific and confirmed at RFQ. No pin-compatible direct replacement exists from Schneider — a substitution requires requalifying the mounting interface and torque envelope.
