MAINTENANCE OF BEARINGS
OIL LUBRICATED BEARINGS
Oil level is measured through sight glass. Oil level
must not fall below center of site glass. An increase in
level may be noted after start up due to oil circulation
within the bearing frame. Change Oil after 200 hours
for new bearings, thereafter every 4000 operating
hours or 6 months, which ever period is shorter.
Change oil every 2000 operating hours under severe
operating conditions, such as high temperature services
[pumpage temperatures in excess of 325°F (160°C)].
We recommend using Table 5 to help determine your
lubricating oil needs.
