Selection notes

Confirm the complete shaft-train lubrication specification, shared gearbox requirements and hydraulic control-fluid chemistry. RO and enhanced anti-wear turbine oils are alternatives only when the OEM permits them.

Product families for technical selection, not a direct interchange chart. Confirm the exact grade, current UAE product data sheet, OEM approval and lubricant compatibility before use.
