    • ⭐⭐⭐⭐⭐ Excellent Quality Bearings – Perfect for My Treadmill Repair
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. ... show more

    • Quality in a small bearing
Review Image by JM-GM
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. ... show more

This bearing comes in 2 pack and it fits just like the OEM bearing on the pulley. Since the dealer doesn't sell just the bearing or pulley. You have to buy the whole assembly so with this. You definitely save a lot of money. The bearing is super smooth and quiet. It spins with the belt on with no issues or noise. Again just like the factory NSK bearings. Performs great and though there's no country of orgins anywhere on the bearing or box. Quality of way better than the Chinese made stuff. ... show more

    • 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.
