                                                                                                   In oil+air lubrication, a quantity of oil metered volumetrically by a pump or distributor is pulled apart
                                                                                                   by a continuous air flow in a tube and carried along the tube wall in the direction of compressed-air
                                                                                                   flow. The quantity of oil is fed into the air flow in pulses at a mixing point (mixing valve). A nearly
                                                                                                   continuous flow of oil is produced that leaves the outlet nozzle as fine drops and is fed to the rolling
                                                                                                   bearing without contact. This means that the bearing housing is under a slight overpressure, which
                                                                                                   keeps dirt away from the sensitive bearings. The carrier air leaves the bearing nearly free of oil.
                                                                                                   - One pump unit for both bearings
                                                                                                   - Inlet line on top of each bearing delivers an oil mist
                                                                                                   - Outlet line on bottom recirculates liquid oil back to the pump unit


                                                                                                   Bearings: Static Oil Lubrication System (Trico Oiler)
                                                                                                   Static oiler lubrication systems are designed to maintain a predetermined oil level in a sump. If the oil
                                                                                                   level drops below a certain point, the depleted oil automatically self levels based on the lubricators
                                                                                                   volume. This adds the right amount of lubricant, increasing efficiencies in the equipment.
                                                                                                   - Separate TRICO Oiler unit for each bearing
