Gearboxes

The GTM Planetary Gearboxes, used in factory automation applications, is reportedly rated up to 10 dB less than other gearboxes, due to its small internal cavity designed to reduce noise. A large taper bearing, for longer life and higher radial and axial loads, serves as a pump that reduces oil amounts in horizontal, vertical, or angled applications; hence, the gearboxes lower inventory and create less friction and heat.
