Using these bearings from an Industrial and Scientific supplier, our team found that they were easy to install AND offered steady and reliable performance. We appreciated that they were shielded, which helped to reduce external damage to our machinery. The bearings were also made with quality materials that are resistant to wear and degrade. While the price point was a bit higher than some other options, we feel that the overall value and performance outweighed this minor downside. Overall, an excellent choice for any business investing in good Power Transmission Products. .
