Double row self-aligning ball bearings 2211K

Double row self-aligning ball bearings 2211K (Self-aligning ball bearings 2211K/2211K spherical roller bearings) provide misalignment compensation, low friction, and high load capacity for industrial applications.

Specification

SEODescription

The Double row self-aligning ball bearings 2211K is a robust bearing solution designed for applications requiring high radial load capacity and misalignment compensation. The 2211K model features a bore diameter of 55 mm, outer diameter of 100 mm, and width of 25 mm, with a dynamic load rating of 38.5 kN and static load rating of 16.8 kN. It operates efficiently at speeds up to 6,300 rpm under grease lubrication. The Self-aligning ball bearings 2211K excels in environments with shaft deflection or mounting inaccuracies, thanks to its spherical outer ring raceway. Widely used in industrial machinery, conveyors, and agricultural equipment, it offers durability in temperatures ranging from -30°C to +120°C. While the 2211K spherical roller bearings (note: technically a ball bearing variant) provide low friction and vibration resistance, their axial load capacity is limited compared to tapered roller designs. Key advantages include extended service life, reduced maintenance needs, and adaptability to harsh operating conditions.

SEOQandA_Product

question:What causes excessive heat in Double row self-aligning ball bearings 2211K during operation?
answer:Excessive heat is often due to overloading, improper lubrication, or misalignment. Ensure correct load limits, proper lubrication, and alignment.
question:How to address increased vibration or noise from 2211K bearings?
answer:Check for contamination, wear, or misalignment. Clean bearings, replace damaged components, and verify proper installation alignment.
question:Why does 2211K bearing lubrication degrade prematurely?
answer:Premature lubrication degradation results from high temperatures, contamination, or incorrect lubricant type. Use recommended lubricants and seal properly.
question:How to prevent premature failure of 2211K bearings?
answer:Avoid overloading, ensure proper installation alignment, use correct lubrication, and protect from contaminants to extend bearing life.
question:What causes uneven wear patterns in 2211K bearings?
answer:Uneven wear typically stems from shaft deflection, misalignment, or improper mounting. Inspect shaft rigidity and realign components correctly.
