Selection notes

Match the gearbox oil viscosity and chemistry to the manufacturer. Check water ingress, operating temperature and motor bearing grease compatibility. Never mix PAO and PAG oils without a validated conversion procedure.

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.
