Overview
This industrial spherical bearing is engineered to deliver exceptional reliability in heavy-duty machinery where shaft misalignment and high radial loads are common challenges. Featuring a precise 1.38-inch bore diameter and a robust 3.15-inch outside diameter, the unit is constructed from high-grade steel to ensure superior durability against wear and corrosion. With a compact width of 1.22 inches, this component fits seamlessly into space-constrained assemblies without compromising structural integrity. The design specifically addresses the need for self-alignment, allowing the inner ring to adjust automatically to angular deviations caused by shaft deflection or mounting errors. This capability significantly reduces stress on adjacent components and extends the overall service life of the equipment. Rated for a dynamic load capacity of 6,890 lbs, it provides consistent performance under rigorous operational conditions, making it an essential choice for maintaining uptime in critical industrial applications.
Key Features
Self-aligning design compensates for shaft misalignment up to several degrees High dynamic load rating of 6,890 lbs supports heavy rotational forces Tapered bore configuration enables secure locking and simplified installation Constructed from premium steel for enhanced resistance to fatigue and deformation Compact 1.22-inch width optimizes space utilization in tight mechanical assemblies Precision-ground raceways ensure smooth rotation and reduced friction C3 internal clearance accommodates thermal expansion during high-speed operation
