Tramec XC89 40:1 Worm Gearbox – 35mm Hollow Bore
This Tramec XC89 40:1 worm gearbox is a compact X-series right-angle worm gearbox with a 35mm standard hollow output bore. The XC version is the compact IEC motor-mount format, designed for machinery where a short input assembly, reliable speed reduction and clean motor fitment are required.
This listing is for the gearbox only with selectable IEC motor input options. No electric motor is included unless stated separately.
Gearbox Overview
The XC89 size uses Tramec’s compact motor input arrangement and a hollow output shaft for direct shaft mounting. With a 40:1 reduction ratio, this model gives an approximate output speed of 35rpm from a 1400rpm input, making it suitable for applications requiring controlled right-angle speed reduction.
Note: XC89 is a compact XC-only Tramec X-series size. It is not listed as an XA/XF shaft or bell-and-coupling version in the catalogue.
Why Choose This Configuration?
This exact configuration is best suited to buyers who need a Tramec XC89 gearbox with a 40:1 ratio, 35mm hollow bore and one of the listed IEC motor input options. At 1400rpm input speed, catalogue output speed is approximately 35rpm, with 355 Nm geared-motor output torque, 1.8 kW recommended motor power and a catalogue service factor of 1.1.
