WORM GEARBOX: VP 075 P R80 80B14 B3 B

Materials and properties
The housing of the gearboxes from size 25 up to size 90 is made of pressure die casting aluminium. The housing of the gearboxes from size 110 up to size 150 is made of grey cast iron. All worms are made of high strength, case-hardening alloy steel and are case-hardened, hardened and subjected to stress relieving. The helical wormwheels are made of high wear resistant bronze. The hollow output shafts are made of grey cast iron.
Lubrication
All SATI VP, VI, VR, VC and VS series gearboxes are supplied complete with lubricant. From size 25 to 90, the gearboxes are lubricated with synthetic oil and do not require any maintenance; for this reason, they are called lifetime gearboxes. These maintenance-free sizes have no plugs. From size 110 to 150, the gearboxes are lubricated with mineral oil and are supplied with the required oil amount for the mounting position B3. For mounting positions other than B3, it will be the responsibility of the customer to adjust the oil amount to the needs of the specific mounting position. It is also necessary, at the time of installation of the gearbox, to replace the filler plug, supplied closed for reasons of transport, with the breather plug supplied with the gearbox itself. Failure to install the breather plug can lead to gearbox malfunctioning and possibly oil leakage. It will also be necessary to remember to install the level and unloading plugs in the correct place for the specific mounting position. For sizes from 110 to 150, after the running-in phase (approximately 300 hours of operation) we recommend changing the oil.
Operating temperature
All the gearboxes in the new SATI range are suitable to operate up to a maximum continuous temperature inside the gearbox of +85°C. The shaft seals are made of acrylonitrile compounds. For continuous operating temperatures higher than + 85°C, it is necessary to contact the SATI Engineering Department for advice. The minimum temperature at which the gearboxes can operate is -5°C. For ambient temperatures <-5°C or >+40°C, it is recommended to contact SATI technical service.
Painting
All SATI gearboxes are epoxy powder painted in the colour RAL 9006 grey, except for the machined parts, for fixing supports and couplings.
