Double row self-aligning ball bearings 2213K

Double row self-aligning 2213K bearing provides misalignment compensation and radial load support. The 2213K self-aligning bearing features dual-row construction, while the 2213K double row bearing ensures smooth operation in applications requiring angular adjustment and reduced friction.

Specification

SEODescription

The Double row self-aligning ball bearings 2213K (2213K self-aligning bearing) is designed to accommodate misalignment and axial displacements in rotating systems. This 2213K double row bearing features a bore diameter of 65 mm, outer diameter of 120 mm, and width of 31 mm, optimized for radial load capacities up to 38.5 kN dynamically. It operates effectively within a temperature range of -30°C to +120°C, with grease or oil lubrication options. Widely used in heavy machinery, agricultural equipment, and conveyor systems, its dual-row spherical design compensates for shaft deflection up to 3°, ensuring smooth operation under misaligned conditions. Key advantages include reduced friction, extended service life, and vibration damping. However, it has limited axial load capacity compared to tapered roller bearings and requires precise mounting alignment for optimal performance.
