Spherical roller bearings are dedicated to extremely severe applications and must support high loads, severe misalignment, contaminated environments, shocks, and vibrations. And with the industry’s highest load rating and production coming from a factory near you, there’s no reason to look anywhere else for spherical roller bearings.
- Reduced friction torque (as much as 30% less), offering lower operating temperature, with lower power and lubricant consumption.
- Appreciably increased operating speed, allowing an extended scope of applications.
- High temperature capacity of up to 200°C (392°F) for metallic cage bearings. Dimensional stability is ensured by a specific heat treatment.
- A +/- 0.5° misalignment capability, without reducing the load capacity, and up to 1° 30’ in case of low loads.

Cylindrical roller bearings have rollers that provide a modified line contact with the cylindrical inner and outer ring raceways, while the rollers are guided by ground ribs on either the inner or outer ring. The cylindrical shape allows the inner ring to have axial movement relative to the outer ring.

Double-row, self-aligning bearings utilize an inner ring with a single spherical raceway. In this configuration, the inner and outer rings can be misaligned relative to each other. The resulting effect is a comparatively large single angle that imposes moment loads upon the balls.

TWO OPTIONS TO PREVENT ELECTRICAL
Electrical pitting often occurs in bearings used in electrical equipment, such as motors and power generators, as a result of current leakage. An electrical current present near a bearing can flow to the inside of the bearing, causing sparks that damage the rolling contact surface, ultimately leading to bearing failure. This electrical pitting and can be prevented with coated bearings or ceramic hybrid bearings.

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.
- 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.
