Discontinued on the OEM record - the supply window is independent channel only
The GBX1200051081D: Procurement posture for this code is therefore quoted-to-order against the BOM line, with availability, quantity and unit price settled when the RFQ lands - no implied stock-holding, no implied immediacy. The mating GBX-series gearhead and the matching Lexium servo adapter are the surrounding line items that typically travel with this gearbox on the same bill of materials and are sourced through the same channel.
Torque envelope - 195 N.m continuous vs 312 N.m peak decides the application
The continuous output torque is 195 N.m and the maximum output torque is 312 N.m, so the gearbox is rated for sustained motion work at the lower figure with roughly 1.6x headroom for acceleration and shock loads. That continuous number, not the peak figure, is the one that sizes the application: a conveyor or index drive running near the peak continuously will not reach the published service life.
Mechanical envelope - 120 mm frame, IP54 shaft seal, 30 000 h rating
The gearbox external diameter is 120 mm, the housing is black anodized aluminium with a C 45 shaft, and the unit is lubricated for life. Service life is 30000 h at 100 rpm at 30 °C - that life figure is conditional on the operating speed and the housing temperature, not a generic warranty number, and it is the curve to derate against in warmer cabinets or higher-speed applications. Shaft sealing is IP54, which is dust-protected and splashing-water resistant - it is an indoor, sheltered-enclosure rating, not a washdown or outdoor rating. Maximum radial force Fr is 1500 N at 100 rpm over the 30000 h life and 2000 N over 10000 h, with the force applied at mid-distance from the output shaft; maximum axial force Fa is 2100 N over the 30000 h life and 2800 N over 10000 h at 100 rpm, 30 °C. Mounting position is any position and ambient temperature for operation is -25 to 90 °C, so orientation on the machine is flexible but the 90 °C ceiling - not the more typical 40 °C industrial rating - is the figure to budget against in enclosed cabinets. Noise level is 65 dB at 1 m no-load, useful as a baseline for cabinet acoustic planning when several gearheads run together.
