- thrust ball bearing for high load capacity
- gear box shape which allows effective heat dissipation giving increased duty cycle
- radial guide of the wormwheel for increased stiffness and improved efficiency
- raised cover with bronze guide against radial load for acme screw;
the raised cover may also be used as a spigot diameter
- grub screw which prevents the threaded cover unscrewing
acme screw in steel C 43 (UNI 7847), whirled thread
2 - worm shaft with true involute, ground worm profile ZI (UNI 4760), made in steel, case-hardened
- bronze wormwheel with true involute profile ZI (UNI 4760), the length of the internal nut is double respect to SJ Series;
the bigger mass of the bronze nut allows a higher duty cycle and a longer life
- synthetic oil lubricated worm gearbox for a better heat dissipation;
this allows higher input speed, improved efficiency and longer life
- radial lubricant seal
- O-Ring as lubricant seal
- breather
13 - oil level plug
14 - oil drain plug
