Double Row Self Aligning Roller Bearing 23128CA Roller Spherical Bearing 140x225x68 For Heavy Load

The 23128CA spherical roller bearing plays an important role in industrial mechanical transmission systems as a double-row spherical roller bearing. The model designation has specific meaning: "231" identifies the bearing series; "28" indicates the inner diameter size of 140mm (calculated as 28×5); "CA" denotes a brass solid cage design, providing unique performance advantages.

• Self-aligning Structure: Features a spherical outer ring raceway and two inclined inner ring raceways with barrel-shaped rollers. This design provides strong self-aligning capability (1°-2.5° allowable angle), compensating for shaft deflection and installation misalignment to reduce stress and wear.
• Cage: Brass solid cage (CA type) provides excellent mechanical strength and wear resistance. Ensures proper roller distribution and smooth operation with low noise characteristics.
• Rolling Elements: Barrel-shaped rollers with linear contact to raceways provide high radial load capacity and can withstand bidirectional axial loads for complex stress conditions.

• High Load-bearing Capacity: Excellent radial load capacity suitable for heavy-duty applications in mining, metallurgy, and papermaking industries.
• Good Wear and Fatigue Resistance: Manufactured from high-quality bearing steel with rigorous heat treatment for high hardness and toughness, ensuring long service life in harsh environments.
• Stable Operation with Low Noise: Self-aligning function and optimized roller-raceway contact reduce vibration and noise, improving equipment stability and operational precision.

• Mining Machinery: Crushers, ball mills, and vibrating screens where high impact loads and vibrations require robust bearing performance.
• Metallurgical Equipment: Gearboxes of rolling mills and continuous casters operating under high temperature, high load conditions.
• Papermaking Machinery: Drying cylinders and press rolls in paper machines where shaft deflection and misalignment are common.
• Power Equipment: Hydraulic generators, wind turbines, and large motors where shaft deformation and vibration compensation are critical.
