5.7 Bearings, Lubrication, and Bearing Frame
5.7.1 Bearings
5.7.1.1 DesIgn. Two rolling element bearing assemblies shall be provided: one assembly free to float within the frame to carry radial loading only. and the other assembly arranged to carry both radial loading and axial thrust.
5.7.1.2 Life. Bearings shall be selected in accordance with ANSI/ABMA-9, ANSI/ABMA-Il. and 150 281. The minimum L10 bearing tile shall be 17.500 hr in the alIowaLle operating region as defined in para. 7.1.6 and for all standard and optional arrangemenls of hearings, lubrication, shafts, covers, sealing, and impellers.
5.7.1.3 End Play. The maximum end play ad the shaft assembly shall not exceed the internal axial clearance for the thrust bearing utilized. Minimum and maximum shaft end play values shall be published in the pump manufacturer’s instruction manual.
5.7.2 Lubrication
5.7.2.1 Oil bath lubrication is standard.
5.7.2.2 Oil mist lubrication shall be optional. When oil mist lubrication is specified, the location ad the inlets, drains, and the vents should he mutually agreed upon between the purchaser and the supplier.
5.7.2.3 Greased for life or regreaseable lubrication shall be optional. When regreascable lubrication is specified, a means for grease relief shall be provided.
5.7.3 Bearing Frame. Bearing frame shall be constructed to protect the bearing,s from water, dust, and other contaminants and provide lubrication for the bearings. The standard design is for oil bath lubrication and is to include labyrinth-type hearing isolators, a 1-in. (25-mm) bull’s eye oil sight gLass. magnetic drain plug, and plugged top vent
5.7.3.1 SealIng. The standard design is to include lahvnnth-type bvanng isolators. In addition, Llt,on.al designs may be offered that allow for the use of a variety of other hearing frame seals, such as lip seals or magnetic oil seals, as may be specified by the purchaser. in those cases where the bearing frame seal does not allow the hearing frame prrs’.ua to equalize with atmospheric pressure during operation, an expansion chamber or breather is necessary.
5.7.3.2 Bearing Frame Drain. Bearing frame shall he provided with a tapped and plugged drain hole at its lowest point. A magnetic drain plug shall be used.
57.3.3 Lubricant Leve4 Indication. Bearing frame for oil bath lubrication shall be provided with a 1-in. (25-rnni) buids eve level indicator that is capable of optionally being installed on either side or both sides
