Updated review, 10/2025, These worked so well I purchased two more two packs to rebuild my mower spindles as these are the same numbers. While there were multiple different bearing manufactures for this specific size, I chose the Timken bearings based upon previous experiences with the brand. I have rebuilt transmissions from over the road trucks to very small electrical motors and the Timken brand was always spec on with their tolerances. These bearings fit perfectly into the castings and onto the motor shaft with minimal effort. Once the rebuilt electrical motor was reinstalled into the pump system it ran perfectly and was as quiet as a new motor. In the future this will always be my brand of choice first.

Exact fit for OEM replacement at 1/3 the cost. Quality and construction was excellent at a great value.

Came well packaged. Installed them and they fit perfectly. The snowblower is back in service.

Quality bearing, worked great. Fixed the bad spindle for a fraction of a replacement. Tap out the old, tap in the new ....

Used these bearings in my Pentair pool motor and they fit perfectly. Easy replacement.

How could I go wrong with TIMKEN bearings? I’ve installed timken bearings in every thing from motorcycles to all types of automobiles. These were installed in my wife’s treadmill rollers. Perfect match. Belt runs quite as a mouse !

Great replacement bearings for pool pump.
