When I tried this product for the first time Im impressed with how well it works .The packaging was great and the quality of the bearings is top-notch. The NTN Bearing 627ZZ Clearance Shielded is a perfect fit for my industrial needs. It is sturdy and has a long lifespan. The only downside is the price, but I would say it's worth it. Overall, i highly recommend this product to anyone in the Industrial and Scientific field needing reliable bearings..
