As a result of using this bearing, I found that it delivers excellent sealing performance keeping grease and oil inside where it belongs. The seals fit perfectly and are easy to install without any hassle. The high-quality construction ensures the long-term durability and smooth operation for high-speed driving .However, the only con is the price as it's slightly expensive compared to some other brands, but it's worth the extra investment for top-notch performance. Overall, I highly recommend NaSee full review
