microlube gbu-y 131

Special grease for the lubrication of rolling and plain bearings subject to humidity and water.

MICROLUBE GBU-Y 131 is a special grease incorporating a semi synthetic base oil and metal complex soap thickener. This special combination greatly influences the load carrying capacity, water resistance and corrosion protective characteristics of the grease.

  • MICROLUBE GBU-Y 131 is intended for the lubrication of plain and rolling bearings operating under medium to high loads as well as under the influence of humidity and water. MICROLUBE GBU-Y 131 has proven particularly successful for lubrication of the fixed or detachable rope grips of ski lifts.
  • MICROLUBE GBU-Y 131 can be applied by brush, spatula, grease gun or grease cartridge. Compatibility with elastomers and plastic materials should be checked prior to series applications as constructional materials may vary greatly from differing manufacturers and suppliers.
  • Good pressure absorption capacity
  • High resistance to water
  • Good corrosion protection
