Nigtight UMF
Nigtight UMF is grease, mainly consisting of refined mineral oil, thickened with urea compound, without adding any solid lubricants that cause pipe clogging. Nigtight UMF exerts excellent lubricity without seizure even under high-loaded severe conditions, and has good resistance against runoff of water-soluble coolant as having excellent adhesiveness and water resistance.
