SKF Traffic light concept Operating temperature range of greases –50 Unsafe functioning (only for short periods) Safe functioning i.e. with predictable grease life LGWA 2 LGGB 2 LGLT 2 LGWM 1 LTL – Low-temperature limit: The lowest temperature at which the grease will allow the bearing to be started up without difficulty. LTPL – Low-temperature performance limit: Below this limit, the supply of grease to the contact surfaces of rolling elements and raceways may become insufficient. Values are different for roller and ball bearings. HTPL – High-temperature performance limit: Above this limit the...
