In addition to the required viscosity, the lubricating oil must meet the following requirements:

  • CLP oils according to DIN 51517-3
  • Micro-pitting test according to FVA, FV no. 54/ I-IV, GFT class high, damage force level >10

When using synthetic oil, SEW-EURODRIVE recommends using lubricants based on polyalphaolefins (CLP HC).

If required, a cooling system must be used (see chapter "Lubricant change intervals" in the "X..e series helical and bevel-helical gear units" operating instructions). Observe the operating temperature of the gear unit when specifying the oil change intervals.
