PRODUCT DESCRIPTIONS

Yilmaz Reduktor N series gearboxes have a one-piece (monoblock) housing, which has advantages in terms of rigidity, oil leakage, noise level and gear strength. The high gear quality achieved with modern manufacturing technologies is supplemented with housings made of GG20-22 material. N series gearboxes are easy to mount and flexible in usage. Depending on customer requirements direct or IEC B5 or B14 motor connections are available. All models are flange-mounted and have two or three stages in a single housing.
