The gears from steel C45 are now also available with inductive hardened teeth. From module 1 to module 5, with many numbers of teeth, directly from stock. By the hardening, the transmittable torque is three times higher than unhardened. If a higher torque is not required, the lifespan will be very much higher than from the standard gears. The dimensions are the same like the standard gears. So it is possible to replace them without modification. The hubs and bores are not hardened and can get easily machined, if needed. A reworking of catalog parts on customers request is possible within 24 hours.
