Standards
Lubricating oils are classified into ISO VG viscosity classes according to ISO 3448 and DIN 51519.
ISO class | ISO 6743-6 designation | DIN 51519 designation | AGMA 9005-D94 designation |
|---|---|---|---|
150 | ISO-L-CKT 150 | CLP HC 150 | AGMA 4 EP |
220 | ISO-L-CKT 220 | CLP HC 220 | AGMA 5 EP |
320 | ISO-L-CKT 320 | CLP HC 320 | AGMA 6 EP |
460 | ISO-L-CKT 460 | CLP HC 460 | AGMA 7 EP |
680 | ISO-L-CKT 680 | CLP HC 680 | AGMA 8 EP |
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.
