Components
Cylindrical gears
Typically, spur or helical gears by Katsa are of the size Ø200-2000 mm and their weight ranges from some tens of kilos to a few tonnes. Our scope of supply includes gearwheels and gear rims also over Ø 2000 mm. The quality class is normally DIN 4-7 and the module sizes vary from 2-25, but we cut even larger teeth on a project basis. Katsa has the capacity to balance high-speed gears to quality class G2,5 according to ISO 21940-1.
Double-helical gears
Double-helical gears are usually of the size Ø300-1200 mm and weigh up to 4 tonnes. The quality class is typically DIN 4-7. Due to the tooth grinding, the gap must be a minimum of 70 mm, sometimes even more, depending on the number of teeth and the helix angle. Katsa has the capacity to balance fast rotating gears to quality class G2,5 according to ISO 21940-1.
Gear shafts
Gear shafts are typically of the size Ø150-600 mm and length 300-1800 mm. At the longest, a case carburized gear shaft may be as long as 2500 mm. Gear shafts may also feature double-helical toothing. The quality class is typically DIN 4-7. Katsa has the capacity to balance fast rotating gear shafts to quality class G2,5 according to ISO 21940-1.
