• Wide service-temperature range • Long-performance grease • Excellent low-temperature properties • Anti-rust properties • Noise-suppressing properties • No intentional polytetrafluoroethylene (PTFE) or per- and polyfluoroalkyl substances (PFAS) Performance life at elevated temperatures Performance life of MOLYKOTE® BG 555 Grease lasts several times longer than those of other wide- temperature range roller bearing greases available in the market. (See Figure 1.) MOLYKOTE® BG 555 Grease is suitable for use in bearings at elevated temperatures for long periods. Moreover, in general conditions, MOLYKOTE® BG 555 Grease can largely extend the intervals of grease repacking or bearing replacement. Noise-suppressant properties Impurities are removed from the main raw materials of MOLYKOTE® BG 555 Grease. The additives are strictly selected and base oil having appropriate viscosity is used. In addition, MOLYKOTE® BG 555 Grease is manufactured by a special process in a dust-free factory. Therefore MOLYKOTE® BG 555 Grease can achieve quieter bearing performances. Low-temperature properties MOLYKOTE® BG 555 Grease is made from excellent synthetic lubricating oils and designed so that the structure causes the least internal resistance. (See Figure 2.)
