SPM 1500 1/2 GREASE FOR HEAVY-DUTY UNITS
SPM-1500-1/2 (МС 51.23.8-1/2) is complex lithium lubricating grease based on synthetic oil. It contains polymers improving adhesion and oil bleeding, as well as anti-friction, extreme pressure and antioxidant additives.
It is designed for roller & plain bearings and friction joints where NLGI ½ consistency is required.
