Spherical roller bearings are double row, self-retaining units comprising solid outer rings with a concave raceway, solid inner rings and barrel rollers with cages. The inner rings with cylindrical or tapered bores.
Spherical roller bearings have two rows of rollers, a common sphered outer ring raceway and two inner ring raceways inclined at an angle to the bearing axis The centre point of the sphere in the outer ring raceway is at the bearing axis. Therefore, the bearings are self-aligning and insensitive to misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection.
Shown in the figures, types EA, C, CD, CA, which are designed for high load capacity, are available. Types EA, C, and CD have pressed steel cages; and type CA has machined brass cages. Type EA has especially high load capacity, features low torque, and has a high-strength cage.
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.
