This bearing is a total disappointment. The design is flawed and faulty. i didn`t even get to use it for a week before it started making grinding noises. I had to replace it sooner than expected. The only good thing about this product is that it arrived on time. But even that doesn't justify its high price .Don't be fooled by its fancy packaging. it's definitely not worth the money. Stick to reputable brands and reliable sellers in the Industrial and Scientific category if you want to save yourself from frustration and wasted money..
