KLUBER ASONIC HQ 72-102  ASONIC® HQ 72-102 High-temperature lubricating grease for low-noise rolling bearings Product Information 5.432 e Edition 06.03, replaces edition 07.01 GATE-B/HS Description: ASONIC HQ 72-102 is a synthetic high-temperature lubricating grease. Due to the careful selection of product components ａnd the clean manufacturing environment, ASONIC HQ 72-102 is a rolling bearing grease with a particularly low noise level. Application: In a wide variety of ball bearings operating under extreme thermal stress, ASONIC HQ 72-102 is used for economical long-term or lifetime lubrication. Examples are ball bearings in electric motors, fans, power-tool pumps, textile machinery, office equipment, household appliances ａnd automobile components such as belt tensioners, guide pulleys ａnd air conditioners. Application notes: The lubricant is applied by means of a spatula, brush, grease gun or grease cartridge. For use in automatic lubricating systems, the pumpability of the lubricant should be checked. Certain polyurea greases solidify during elongated periods of storage. Normally, such increase in consistency does not affect the performance of the lubricating grease ａnd is reversible when the grease is subjected to shearing or working stress.

Lubricants change their consistency, apparent dynamic viscosity or viscosity depending on the mechano- dynamical loads, time, pressure ａnd temperature. These changes in product characteristics may affect the function of a component. ** Klüber viscosity grades: EL = extra-light lubricating grease; L = light lubricating grease; M = medium lubricating grease; S = heavy lubricating grease; ES = extra-heavy lubricating grease *** Speed factors are guide values which depend on the type an size of the rolling bearing type ａnd the local operating conditions, which is why they have to be confirmed in tests carried out by the user in each individual case.
