What does a sleeve bearing on a motor mean?
Th e life of a sleeve bearing is practically infi nite, pro- vided that its operation remains within the specifi ed conditions. Motors have sleeve bearings at both ends. Th e bearing on the D end is the guide bearing and means that it can tolerate a limited non-axial force. Th e bearing on the N drive end is isolated.
Why does my spa pump keep seizing up?
A pump will commonly seize due to worn out bearings or trapped debris/foreign objects. The remedy is replacing the spa pump. While there are companies that rebuild pumps, this is often just as expensive (or more) as purchasing a new one.
How does a spherical roller thrust bearing work?
Spherical roller thrust bearing In Spherical Roller thrust bearings, the load is transmit- ted from one raceway to the other at an angle to the bearing axis. Th ey are suitable for the accommodation of high axial loads in addition to simultaneously acting small radial loads. Spherical roller thrust bearings are also self-aligning.
What kind of lubrication is used on bearings?
Th e bearings are lubricated by hydrodynamic lubrication, which can be of a self-lubricating or oil circulation type. Th e bearing shells are spherically-seated in the hous- ing. Th e oil fl ow of self-lubricated bearings is guaranteed by the central arrangement of the oil ring.
How to replace a bearing on a pool pump?
Disconnect the motor from the pump housing as you would in a new motor replacement. Ensure that there is no electricity to the pump. Disconnect the motor from the pump housing; disconnect the electrical conduit and bonding wire; remove the diffuser, impeller, seal plate and pump bracket.
What do you need to know about bearing replacement?
Anatomy of a motor: Brush up on your motor skills with this illustration pinpointing parts that you’ll disassemble in the event of a bearing malfunction. For a bearing replacement, we’re primarily concerned with the shaft, ball bearing assembly and the rear and front end (also called shaft end) bells.
