The grease MS-70 (GOST 9762-76) is a low-viscosity petroleum oil solidified with ceresin wax; contains a viscous additive.
The basic operational characteristics: high water resistance, conservation properties and frost resistance; provides periodic work of mechanisms within 10 years. It is efficient at temperature-45 … +65°С, in powerful mechanisms — from-50°S.
Scope: the rolling and sliding bearings, directly adjoining to sea water.

Data on operational temperatures represent values which are guided by a structure of lubricants, and also on a scope and technology of use. Depending on a kind of mehaniko-dynamic loading lubricants change the consistence, conditional viscosity or viscosity at various temperatures, pressure and duration of operation. These changes of indicators can affect work of components.
