Shell Morlina S2 BL 22 is an innovative blend of low-viscosity, solvent-refined mineral oil that's mixed with zinc-free additives. Because it meets ISO grades 2, 5 and 10, it's well-suited to lubricate high-speed spindles in machine tools, circulating systems, and machine bearings, including plain and rolling-element bearings. Shell Morlina S2 BL 22 has a long oil life and works hard to prevent oxidation and rust, saving you time and money. Because it's extremely corrosion-resistant, this lightweight oil is ideal for wet, hot environments.
