* Note that it normally takes 2 hours for bearing temperature to stabilize and the final temperature will depend on the ambient, r/min, pumpage
temperature and pump size. Also some oils have a very low pour point and good viscosity index which extend the minimum temperature
capability of the oil. Always check the grade capability where the ambient is less than -5 ºC (23 ºF).

Note: the bearing sizes do not constitute a
purchasing specification.
Grease lubricated bearing housings are fitted with
"sealed for life" bearings.
5.2.3 Lubrication schedule
5.2.3.1
Oil lubricated bearings
Normal oil change intervals are 4 000 operating
hours or at least every 6 months. For pumps on hot
service or in severely damp or corrosive
atmosphere, the oil will require changing more
frequently.
Lubricant and bearing temperature analysis can be
useful in optimizing lubricant change intervals.
The lubricating oil should be a high quality mineral
oil having foam inhibitors. Synthetic oils may also be
used if checks show that the rubber oil seals will not
be adversely affected.
The bearing temperature may be allowed to rise to
50 ºC (90 ºF) above ambient, but should not exceed
82 ºC (180 ºF) (API 610 limit). A continuously rising
temperature, or an abrupt rise, indicates a fault.
Pumps which handle high temperature liquids may
require their bearings to be cooled to prevent
bearing temperatures exceeding their limits.
5.2.3.2
Grease lubricated bearings
The bearings are sealed for life.
