ТУ У 23.2-30802090-084:2008Lithium lubricants for rolling mills Sliding GR1 and Sliding GR2 are intended for greasing rolling work bearings of rolling mills. Lubricant Sliding GR1 is utilized in centralized systems, continuous greasing and lubricant Sliding GR2 is used as a mortgage one. The use of lubricants is permissible in roller and ball bearings units of other industrial equipment, which put forward higher requirements for mechanical and thermal stability under the influence of elevated pressures and temperatures. The lubricants are efficient at the temperature varying from minus 20°С up to 150°С.Guarantee period of storage – 3 years from the day of manufacture.Table 110
