Product Overview: The 21307 Spherical Roller Bearing
The 21307 bearing is a robust and highly adaptable component, belonging to our comprehensive 21300 Series Spherical Roller Bearings. With dimensions of 35mm bore, 80mm outer diameter, and 23mm thickness, this bearing is engineered to excel in applications involving heavy radial and axial loads, especially those prone to misalignment. Its unique design features two rows of symmetrical rollers, a common spherical outer ring raceway, and two inner ring raceways inclined at an angle to the bearing axis. This allows for exceptional self-alignment, accommodating both static and dynamic misalignment that may arise from shaft deflection, housing distortion, or mounting errors.
As a trusted supplier of industrial bearings and mechanical parts, we ensure our 21307 bearings are manufactured to rigorous industry standards, guaranteeing reliable performance and extended operational life in demanding environments. This bearing is critical for maintaining smooth operation and reducing friction in heavy machinery across various sectors.
