I don't think these are real Timkens as they are made in China. I bought it last July and after 4-6 months the bearings failed. At the same time, my calipers were sticking, so I figured that was the cause of their extreme heat and wear. I bought a new pair and also installed new calipers and discs. The wheel bearing failed after 3-4 months. I DD my machine and commute. Tried to contact Timken about warranty but no response as this sale is not warranty related. Big fall. Find
