class 10.9
1) For worm gear reducers UNI 5931-84.
2) The bolts of shrink disc must be gradually and uniformly tightened, with continuous sequence (not diagonally!) and in several phases up to the reaching of maximum tightening torque stated on table.
1) When gear reducers are coupled with servomotors (servogearmotors) the final colors is black RAL 9005.
2) Integrated low backlash planetary servogearmotors.
Note
- Class 8.8 is usually sufficient.
- Before tightening the bolt be sure that the eventual centering of flanges are inserted properly
- The bolts are to be diagonally tightened with the maximum tightening torque.
