SKF 23072 CACK/C3W33 STATIC SMOOTH DRUM ROLLER

The SKF 23072 CACK/C3W33 is a high-performance spherical roller bearing designed for heavy-duty industrial applications. It features a tapered bore type (1:12) with a bore diameter of 14.1732 inches, an outside diameter of 21.2598 inches, and a width of 5.2756 inches. This bearing is engineered to handle substantial radial and axial loads, offering a basic dynamic load rating of 623,395 lbf and a basic static load rating of 1,045,362 lbf. Its fatigue load limit is rated at 75,311 lbf, ensuring durability under cyclic loading conditions. Manufactured to SKF Explorer performance class standards, this bearing provides enhanced service life, higher load capacity, and improved reliability compared to standard designs. The performance class incorporates optimized internal geometry and superior steel quality, reducing friction, wear, and heat generation while supporting higher speeds — with a reference speed of 950 r/min and a limiting speed of 1,200 r/min. The machined brass cage ensures robust operation and lubrication retention, while the radial internal clearance is CN (normal), optimized for standard operating conditions. The bearing is open type, facilitating easy lubrication and maintenance. This bearing design also accommodates shaft misalignment and has excellent resistance to edge stresses due to its precise raceway-shoulder transitions. The SKF 23072 CACK/C3W33 bearing is ideal for applications requiring heavy load capacity, high reliability, and extended service intervals, such as in mining, mineral processing, and heavy machinery industries.
