Selection notes

Confirm oil versus grease lubrication for each bearing. Select pump bearing oil by speed, load, temperature and water exposure. Steam-turbine drivers require their own OEM-approved turbine oil; sealed bearings may need no relubrication.

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.
