en.Wedoany.com Reported - SKF has launched the Cooper sealed split spherical roller bearings, combining innovative split design with high-quality craftsmanship to enable rapid installation, seamless replacement, and simplified repair and maintenance, minimizing operational disruptions and ensuring quick turnaround. Duncan Mngomezulu, SKF Key Account Manager, stated that these bearings are manufactured using world-class materials and designed for long service life, delivering optimal performance, proven reliability, peak efficiency, and extended lifecycle, effectively protecting critical assets and keeping operations running without interruption.
Mngomezulu explained that the split design works in conjunction with a robust sealing system, allowing for quick, direct, and safe on-site bearing replacement or repair in hard-to-reach areas. With minimal interference to shaft alignment, maintenance time, requirements, and costs are reduced, and these bearings can lower Mean Time to Repair (MTTR) by up to 70%. In terms of structural integrity, the bearings utilize an integrated precision-engineered connection method to secure the inner and outer rings. Each unit includes a standard sealing system that retains lubricant, minimizes grease leakage, and prevents contaminant ingress, ensuring reliable performance and reduced maintenance needs throughout the unit's service life. Mngomezulu noted that since there is no need to disassemble couplings or cantilever drives to replace bearings, realignment is avoided, thereby reducing worker exposure to hazards and simplifying maintenance—a feature particularly important in the mining and cement industries, where nearly half of all accidents occur during maintenance and conveyor inspections.
SKF Cooper split spherical roller bearings are manufactured to ISO normal precision and rotational accuracy. Their installed internal radial clearance is based on the mounting clearance of standard (CN) spherical roller bearings mounted on adapter sleeves. Mngomezulu pointed out that this may vary slightly due to shaft tolerance variations, and added that other bearing internal clearances, such as C3, are available upon request. This series of bearings is compatible with a wide range of bearing housings, with each bearing capable of being used with SKF metric and imperial split housings. The split bearing outer ring has the same external dimensions as standard ISO spherical roller bearing outer rings, ensuring seamless compatibility not only with SKF housings such as SNLD, SMS, and SAF/SDAF, but also with split housings from many other manufacturers.
Mngomezulu stated that the series has been expanded to include smaller sizes, broadening the application scope of split bearing technology to scenarios with smaller shaft diameters or space constraints. These bearings are designed for industries such as mining, mineral processing, metals, material handling, cement, pulp and paper, power generation, and food and beverage, with applications covering conveyor rollers, bucket elevators, escalators, agitators and mixers, and horizontal mill pinions. Mngomezulu noted that the unique split design redefines corporate expectations for split bearing technology, reducing operating costs and enabling a rapid return on investment.
