Specification

SEODescription

The Double row self-aligning bearings 2219, also known as the 2219 self-aligning ball bearing or Self-aligning 2219 double row bearing, is engineered to accommodate angular misalignment and axial loads in rotating systems. With a bore diameter of 95 mm, outer diameter of 170 mm, and width of 43 mm, it supports radial and moderate thrust loads. Designed for industrial applications like conveyor systems, agricultural machinery, and material handling equipment, it operates effectively within a temperature range of -30°C to +120°C. The bearing's double-row spherical raceway enables ±3° self-alignment, reducing stress from shaft deflection or mounting errors. Key advantages include high load capacity, durability in harsh environments, and low maintenance requirements. However, its complex design may increase initial costs compared to standard bearings. The 2219 variant excels in applications requiring vibration resistance and prolonged service life under misaligned conditions.
