Product Description
Features and BenefitsApplications
Mobil BEACON 325 is a high performance grease specifically formulated for the lubrication of precision equipment operating at moderate and low temperatures. It is made with a synthetic base oil of extremely low viscosity and low volatility plus a lithium soap. BEACON 325 is characterised by good mechanical stability, a high degree of resistance to water and extremely high oxidation stability. As its base oil viscosity is low and the viscosity index of the fluid is high, the grease has excellent low temperature properties including low starting and running torque at very cold temperatures and good pumpability.
BEACON 325 provides excellent service in a wide variety of small bearings and small, lightly loaded gears that operate over a wide temperature range. Its long lubrication life and excellent oxidation stability well suit it for use as a bearing lubricant in sealed-for-life units in automotive, aircraft and industrial applications. The recommended application temperature range for continuous operation for BEACON 325 is -50º C to120º C.
BEACON 325 is a member of the Mobil brand of lubricating products recognized for their high quality and reliability, as well as performance capabilities. As with other Mobil greases, this product is manufactured to the strictest quality standards. A key feature of BEACON 325 is its use of a synthetic fluid to provide optimum performance for low temperature precision applications. BEACON 325 offers the following quality features:
Application notes: BEACON 325 is formulated with an organic ester synthetic oil. This synthetic oil may cause a softening or swelling of certain plastics, elastomers, paints, or varnishes. How serious the softening or swelling tendency may be depends also on the temperature and the period of contact. Contact your local Mobil representative for further information on materials compatibility.
BEACON 325 provides excellent service in a wide variety of small bearings and lightly loaded gears that operate over a wide temperature range, including such applications as:
Naval, marine, and aircraft instruments and control mechanismsGeared limit switches in Limitorque valve actuatorsCommercial and military electronic equipmentSealed for life motors, generators, and similar equipment in automotive, aviation and industrial applications
