2PACK TIMKEN 6203-2RS Deep Groove Ball Bearing 17x40x12mm

These TIMKEN 6204-2RS bearings are excellent quality and performed exactly as expected. I purchased them to rebuild my Life Fitness F3 treadmill, and the fit and tolerances were spot-on. The bearings were properly sealed, pre-lubricated, and installed without any issues. Once installed, the treadmill ran smoothly and quietly again, just like new. The precision and build quality are what I've come to expect from TIMKEN products. Most importantly, these bearings saved me a significant amount of money compared to replacing major treadmill components or paying for a service call. For anyone repairing fitness equipment, electric motors, or other machinery that uses 6204 bearings, I highly recommend these.

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.

The bearings were perfect and as described. Fast shipping!

Genuine Timken Bearings. I tested them using the WBA Authenticator 2.0 app and they are authentic. They came in a sealed bag of 2 and within them the bearings were individually sealed in their own bags inside the box. QR code in the back. Very happy with my order.

Arrived on time. Fit as replacements for the equipment perfectly. Frankly, these may be better and quieter than the original equipment. Running fantastic.

I like these bearings, they work great for me. I've use others for like wheel bearings.
