Deep groove, or single row radial, ball bearings are the most widely used bearings. They utilize an uninterrupted raceway that makes them optimal for radial loads .This design permits precision tolerance, even at high-speed operation. Besides, ball bearings use standard cages of pressed steel, as well as machined, brass cages for high-speed applications.
Pre-lubricated bearings have integral seals, or shields, which are packed with long-life grease. In many applications, these bearings can be used without supplementary seals, closures, or protective devices. This design also offers the lowest possible manufacturing costs to the end user.
Shielded ball bearings are protected on one or both sides by metal shields that are fastened to the outer ring.
Sealed ball bearings incorporate steel-reinforced rubber seals that are securely fastened to a groove on the outer ring.

• Clean, vacuum-degassed, high-carbon chromium steel that undergoes a proprietary heat treatment to reduce crack sensitivity.
• High-power density that allows a smaller bearing to support higher loads.
• Low-weight, compact designs.
• A wide range of sizes.
