2PCS TIMKEN 6203-ZZ Double Metal Seal Bearings 17x40x12mm, Pre-Lubricated and Stable Performance and Cost Effective, Deep Groove Ball Bearings.

Perfect fit for my Epic View 550 Treadmill. Rear roller was making a clanking noise because the bearings were giving out. Replaced with these new bearings and noise is gone, runs just like new. Saved $140.00 by not having to buy a new roller.

As described, great value, great quality. Would buy again.

Original bearings were squealing like a pig on Easter in West Virginia! These fit perfwct, and got my saw back up and going like when she was new! (The saw, not the pig) have a great day y'all!

Have come to rely on Timken bearings. Have been familiar and used Timken bearings for over 50 years for replacements for electric motors, automotive and trailer bearings. Have always been satisfied with their quality.

Bottom part of my mini bag Jack shaft and they're working well

exact fit, fast service,great value

Used for a delta drill press and fit perfectly.

Bearings were just fine thank you
