General data Single or double antifriction bearing grease lubricated (ball or roller type) or oil lubricated sleeve bearing. The theoretical lifetime of bearings, L10h according to ISO 281/1 standard, of standard horizontal construction generators, without external forces (radial and / or axial) is in excess of 50.000 hours. On request, the lifetime of bearings, L10h can be in excess of 100.000 hours. Locating bearings are on the D end side and floating bearings on the ND end side. Bearing selection Antifriction bearings up to 560 frame size included. Sleeve bearings from 630 frame size included...

Auxiliary device Automatic voltage regulator mounted on board. RTD devices in standard configuration: 1+1 RTD on each phase of stator winding 1 RTD on each bearing Terminals in auxiliary terminal box. Other configurations available: DUPLEX type RTD for inlet / outlet air RTD for inlet / outlet water

Optional features Reinforced construction for high linear vibrations flanged shaft for direct coupling with engine flywheel (in case of single bearing solution) neutral point terminals in separate terminal box terminal box inside air duct (internal terminal box) cooling system IC 86W with additional forced ventilation cooler mounted on side increase protection degree up to IP 54, IP 55 or IP 56 lifted feet to couple the generator with engine on existing baseframe redundant rotating rectifier with 12 diodes insulated bearing and earthing brush AVR supplied loose automatic power factor control...
