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

Well made as always from this company. Good price, good quality.

good quality

I have ordered different kind of bearings in the part. But Timken bearings have always given me good long service. I recommend this bearings and vendor.

The rear roller bearings were worn our and clunking in our Proform Pro 2000 treadmill, so I investigated a fix. The roller with bearings is over $100, but the bearings can be removed and replaced separately. After a few Youtube videos, I was confident it could be done with little effort for ~$15 in bearings. These are ZZ or 2Z, but fit the same space as a Z model. Treadmill is smooth and quiet again, but these do appear to be made in China (box says printed in CN) so Ill update if they wear prematurely.

Excellent Product, Delivered Earlier Than Expected

If your looking to replace the bearings to the mower ball assembly on an older DR Trimmer and dont want to fork out the ridiculous price they want for the replacement then look no further this is it and worked perfectly.

Used these in my table saw to replace bad bearings. Overnight shipping was great . They fit right in and the table saw is humming again. I hope they last a long time.

Replacement bearings for my tablesaw

I used these to rebuild a 40 year old 1 1/2 hp dual voltage single phase electric motor and they worked perfectly just as I expected because I’ve used this brand before.

Bearings were right size as described. Fit the motor I was repairing and worked great. Seller did everything right as well. Happy with my purchase!
