Product Overview: The 21311 Spherical Roller Bearing
The 21311 spherical roller bearing is a robust and high-performance component, integral to our comprehensive 21300 Series Spherical Roller Bearings. Engineered to manage exceptionally heavy radial loads and moderate axial loads in both directions, this bearing is designed to deliver reliable performance even in the most demanding industrial environments. Its defining feature is its inherent ability to self-align, which means it can accommodate significant angular misalignment between the shaft and housing, making it ideal for applications prone to shaft deflection or mounting errors. With a standard bore diameter of 55 mm, an outer diameter of 120 mm, and a thickness of 43 mm, the 21311 offers a versatile solution for a wide range of heavy-duty machinery.
As a trusted provider of industrial bearings, we ensure our 21311 bearings are manufactured to rigorous industry standards, guaranteeing dimensional accuracy, long service life, and consistent performance. This type of bearing is crucial for maintaining operational efficiency and reducing downtime in critical machinery. Explore our extensive selection of spherical roller bearings to find the perfect fit for your specific industrial needs.
