Whisperflo Ball & Roller Bearings - 2 PACK

MADE IN CHINA. I went ahead and used them just so I could get my pool pump going quicker.. Will have to wait and see how long they will last.

Perfect one-for-one replacement for the bearings in my WhisperFlo pump. I did not need a bearing puller to remove the old bearings. I was able to use two large clamps I already had. These bearings seem to have made a significant difference in the efficiency of the pump in addition to being substantially quieter.

If you want your bearings to fail again, this is the way to go. Cheap Chinese manufacturer with cardboard side coverings that allow for lots of slop in spinning and early failure. NSK, made in America, all steel. Almost twice as heavy, no slop in spinning and no disintegration of the bearings should water make it past the pumps ceramic seal, or in my case torrential rains splashing up into a vent despite using a motor cover.I had removed the through bolts holding my motor together and covered the threads with antiseize in anticipation of some rusting. Strongly recommend you check the bottom through bolts before ordering. You may decide to purchase a new front motor housing at the same time, or a replacement motor instead.Not bashing the product for fun, not a fan of busted buckles and doing things twice. Utube is learning from other people's experiences, no need to pioneer yourself. Hope this helps.

worked very well. Be sure to buy a bearing puller to remove old bearings from your motor. You'll use the bearing puller with a wrench to replace (or in some cases a drill...which is over kill).~Former Mechanical Engineer.

Why pay $$$ when you can just fix it yourself. These worked great to fix the high pitched whining noise from my pool pump motor.

Fast shipping and it met my needs. I only gave it 4 stars as they have only been installed for a short period of time; therefore, I do not know how long they will last.

Worked as expected. Allowed me to repair the noisy pump. As quiet as it was when it was first installed 12 years ago.

these seals fit like a glove great product!
