Double row self-aligning ball bearings 2220K

2220K self-aligning ball bearing is a double row 2220K ball bearing with self-aligning double row 2220K design, offering high radial load capacity and misalignment compensation for precision performance in industrial machinery applications.

Specification

SEODescription

The 2220K self-aligning ball bearing is a double-row design featuring a bore diameter of 100 mm, outer diameter of 180 mm, and width of 60 mm. This Double row 2220K ball bearing accommodates combined radial and axial loads up to 135 kN dynamically, with a maximum speed rating of 3,600 rpm. The Self-aligning double row 2220K operates effectively in temperatures ranging from -30°C to +120°C, supporting ±2.5° angular misalignment compensation. Widely used in mining, material handling, and heavy machinery, its self-aligning capability reduces vibration and shaft deflection while maintaining low friction. Key advantages include extended service life in misaligned conditions and reduced maintenance needs. Limitations include higher initial cost compared to standard bearings and reduced suitability for ultra-high-precision applications requiring absolute alignment.

SEOQandA_Product

question:What causes premature failure in 2220K bearings?
answer:Contamination, improper lubrication, or overload. Ensure clean environment and correct load limits.
question:How to resolve excessive noise from 2220K bearings?
answer:Check for contamination, misalignment, or damage. Clean, realign, or replace the bearing if necessary.
question:Why does 2220K bearing overheat during operation?
answer:Overloading, insufficient lubrication, or high-speed operation. Reduce load, relubricate, or adjust speed.
question:How to prevent misalignment in 2220K bearings?
answer:Ensure proper installation and shaft alignment. Use self-aligning design to accommodate minor misalignments.
question:What lubrication is suitable for 2220K bearings?
answer:Use manufacturer-recommended grease or oil. Maintain lubrication intervals and avoid over/under-lubrication.
