Lubrication
page 1 of 1
In cases of ambient temperatures not envisaged in the table, call our Technical Service.
● In the case of temperatures under -30°C or over 60°C it is necessary to use oil seals   with special material.
● For operating ranges with temperatures under 0°C it is necessary to consider the     following:
→ The motors need to be suitable for operation at the envisaged ambient temperature.
→ The power of the electric motor needs to be adequate for exceeding the higher      starting torques required.
→ In the case of reduction units with a cast-iron case, pay attention to impact loads      since cast iron may have problems of fragility at temperatures under -15°C.
→ During the early stages of service, problems of lubrication may arise due to the high      level of viscosity taken on by the oil and so it is wise to have a few minutes of      rotation under no load.
 
The oil needs to be changed after approximately 10,000 hours. This period depends on the type of service and the environment where the reduction unit works.
The reduction units size 025-030-040-050-063-075-090 are supplied complete with      lubricant for life, synthetic oil, SHELL TEVELA OIL 320, and can therefore be mounted      in any position envisaged in the catalogue. V5/V6 for which you should call our      Technical Service to assess the conditions of use.
○ The reduction units size 110 and 130 are supplied complete with lubricant, mineral oil,      SHELLTEVELA OIL 320
○ The variator speed are supplied complete with lubricant, mineral oil, GUANGYAN Ub-3.
○ For sizes 110 and 130 it is necessary to specify the position, otherwise the reduction     units are supplied with the quantity of oil relating to pos. B3.
○ Only reduction units 110 and 130 are fitted with breather, level and oil drainage plugs.      It is necessary, after installation, to replace the closed plug used for transportation      with the breather plug supplied with the unit.
○ PC is supplied complete with life-long lubricant, synthetic oil, SHELL TEVELA OIL 320,      and can therefore be mounted in all the positions. Lubrication is separated from that      of the worm reduction unit.
