Bearing 331905 SKF Shielded bearings have a storage life of five years and a further two years operational life following installation. Wash all bearing parts with a noncontaminating solvent. Lightly pack the bearings with grease applying a 33% fill by volume into the bearing and housings. Where Bearing 331905 SKF space heaters are fitted, and the storage environment has wide humi dity and temperature variations, it is strongly recommended they be energised. Warnings should be placed on the Bearing 331905 SKF to make operatives aware of the live heaters Supplies are normally 220-240 volt single phase, from a 380-415 volt three phase supply. See terminal box lid for details.

Insulation resistance During extended storage a three monthly insulation test is recommended to avoid possible lengthy drying out periods when installing Bearing 331905 SKF. Use a 500 volt d.c. Megger.The insulation resistance between phases and between the windings and the frame should be checked. The insulation resistance should be maintained above 10 megohm. If a lower reading is measured, use one of the drying out methods recommended on page 14 until an acceptable reading is obtained. If heaters are fitted but not energised, they should be used in future. Wound rotors Ideally, wound Bearing 331905 SKF brushes should not be in contact with the slip-rings during storage as there is a risk of corrosion. Brushes should either be lifted off the slip-rings or stored separately. This may not be possible with small Bearing 331905 SKF.
