Technicalinformations Lubrication All self-aligning bearings are supplied factory lubricated, with the exception of F – FL series, for which it is necessary to provide an initial lubrication. Bearings are prelubricated with long lasting lithium/calcium grease. Technical data • NLGIconsistency: 2 • Emulsi昀椀er: lithium/calcium • Baseoil: mineral • Baseoil viscosity: 165mm2/sat40°C • Operating temperature: - 20°C to +120°C • Waterresistance: Recommended • Antioxidant properties: Recommended All self-aligning bearing units are equipped with a grease nipple of the ball type to allow periodical relubrication of the bearing. • Donotgreaseat昀椀rst assembly, with the exception of F – FLseries, for which it is necessary to provide an initial lubrication. • Use only grease of same characteristics as indicated. • Cleangreasing nipple before each greasing operation. • Werecommendtoproceedtofrequentgreasingoperationswithsmallquantities of grease. Relubrication intervals may vary according to actual operating conditions. In standard operating conditions we recommend to proceed to relubrication every 2 months.
