298 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 • NLGI consistency: 2 • Emulsifier: lithium/calcium • Base oil: mineral • Base oil viscosity: 165 mm2/s at 40°C • Operating temperature: - 20°C to +120°C • Water resistance: 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. • Do not grease at first assembly, with the exception of F – FL series, for which it is necessary to provide an initial lubrication. • Use only grease of same characteristics as indicated. • Clean greasing nipple before each greasing operation. • We recommend to proceed to frequent greasing operations with small quantities of grease. Relubrication intervals may vary according to actual operating conditions. In standard operating conditions we recommend to proceed to relubrication every 2 months.
