Sealed Design: The rubber seals on both sides help keep out dirt and moisture, extending the bearing's life. Cost-Effective: Purchasing the 2-pack offered good value, especially considering the quality.

Final Thoughts: Overall, the TIMKEN 6203-2RS bearings have been a reliable choice for my repair needs.

Quality in a small bearing
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.

Good replacement bearing, sealed both sides, for equipment without a zerk fitting.
Arrived on time. Fit as replacements for the equipment perfectly. Frankly, these may be better and quieter than the original equipment. Running fantastic.

Works as intended
after I replaced a 35 year old engine cooling fan assembly pully bearing with another brand which failed after only a few hours of use, I picked up a timken bearing to replace it. It fit perfectly and is still 100% operational after nearly 100 hours of use.
