ES1 Stainless Steel Deep Groove Ball Bearings

Daily cleaning and chemical washdown of equipment and work surfaces in food and beverage and chemical plants can quickly corrode bearings, leading to frequent bearing replacement and machine downtime. NSK ES1 deep groove ball bearings are designed and manufactured to deliver superior corrosion resistance for a longer operating life.
