According to the ISO 281/1 standard, the theoretical lifetime of bearings (L10h) used in standard horizontal construction motors and not subject to external forces (radial and/or axial) is in excess of 50000 hours. On request, L10h can be in excess of 100000 hours. The motors from 63 to 132 frame size have floating bearings. The motors from 160 frame size have locating bearings on the D-End side and floating bearings on the N-End side. On request special bearings are designed where high radial and axial forces are applied.
General Specification:
Antifriction bearings 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 motors, 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. Both bearings are fitted with a regreasing system.The used grease is removed through a valve locked in the outer bearing cover. Sleeve bearings available as an option. On request special bearings are designed where high radial and axial forces are applied.
