Pillow Block Stainless Steel Ceramic Hybrid Mounted Unit Bearings (SBP) are designed to meet all of the most demanding operating environments such as the Food, Beverage or Chemical industry. Pillow Block Stainless Steel Ceramic Hybrid Mounted Unit bearings are ideally suited for applications that require frequent wash downs, operate near food or liquid contaminants and have a high exposure to harsh chemicals or humidity. Ceramic balls allow the bearing to require less energy, spin faster and last longer. Ceramic bearings do not require any lubrication to run. SB Style inserts have an extended inner ring on both sides of the bearing.
