SKF Cooper Split Spherical Roller Bearings
The SKF Cooper split spherical roller bearing is the most popular design in the split range, offering the self-aligning capability and high load capacity of a solid spherical roller bearing with the convenience of a split assembly. It accommodates misalignment, deflection, and high radial loads while permitting fast in-situ replacement. Applications span conveyor pulleys, mine winders, large process fans, and marine line shaft bearings. The split inner ring clamps securely onto the shaft, the split outer ring seats in the housing, and the roller/cage assembly is fitted between them — all without moving the shaft. Seals are also split and attached, completing the contamination protection. This bearing represents a strategic choice for maintenance engineering focused on maximizing uptime and accessibility.

Self-Alignment Maintained
Split design does not sacrifice the spherical misalignment capacity.
Heavy Radial Load Capacity
Two rows of barrel-shaped rollers match solid bearing ratings.
Complete In-Place Assembly
Every component is split for installation around the shaft.
Robust Sealing System
Split seals protect against dust, water, and lose lubricant.
Proven in Critical Conveyor Drives
Standard solution for mining and quarry conveyors.
Lower Total Cost of Ownership
Reduced downtime and labor outweigh marginally higher bearing cost.
Typical Conveyor Pulley Application of Split Spherical Bearings
On underground mine conveyors, changing a solid pulley bearing could halt production for a day. With SKF Cooper bearings, the worn bearing is cut off, and the split replacement assembled in hours, directly inside the confined space, dramatically improving safety and productivity.
Assembly and Alignment Tips for Split Spherical Roller Bearings
Proper alignment of the split housing halves using dowels and feeler gauges is crucial for load distribution. SKF provides detailed fitting instructions and on-site supervision to ensure the full rated life is achieved.
