NTN Spherical Roller Bearing, 22324BD1C3

The Brief Description of Bearings:

Spherical roller bearings are dedicated to extremely severe applications and must support high loads,severe misalignment,contaminated environments,shocks,and vibrations.

NTN 22324BD1C3 sphericals feature the industry highest load rating: a full 18% higher than a standard spherical roller bearing. This level of quality means at least a 75% extension of service life. The performance of these sphericals is achieved through the use of very high quality raw materials and optimized rolling element geometry.

The unique design also leads to:,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 200Â°C (392Â°F) for metallic cage bearings.

Dimensional stability is ensured by a specific heat treatment.,A +/- 0.5Â° misalignment capability,without reducing the load capacity,and up to 1Â° 30 in case of low loads.

NTN 22324BD1C3 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 NTN 22324BD1C3 bearings are self-aligning and insensitive to misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection.NTN 22324BD1C3 Spherical roller bearings are designed to accommodate heavy radial loads, as well as heavy axial loads in both directions
