SKF Cooper Split Tapered Roller Bearings
Split construction with tapered rollers, so the bearing carries combined radial and axial load while still being fitted around a shaft in place. It suits positions that need to be located firmly but cannot be stripped. SES holds the range as an authorised SKF distributor, covering bore range About 50 mm to 500 mm in common sizes; rows Single row, opposed arrangements available; setting End float adjusted during assembly; cage Split machined cage. Executions include single row split tapered executions, opposed pair arrangements for reversing thrust, pillow block housed assemblies, flanged housed assemblies, among others. It is specified most often into locating ends of inclined conveyor drive shafts and winch and hoist drum shafts in workshop and port cranes. Every part is genuine SKF through official channels, with designation, specification and options confirmed against your duty before it ships — supplied from Kolkata and our branch network, with breakdown cover that does not sit in an inbox.

Where it runs.
You will find SKF Cooper Split Tapered Roller Bearings in the parts of a plant where this particular duty actually occurs. In practice that means locating ends of inclined conveyor drive shafts, winch and hoist drum shafts in workshop and port cranes, screw press and dewatering shafts in agro and paper plant, and equally mixer and agitator shafts carrying impeller thrust, inclined bucket elevator head shafts, drive shafts on rotating kiln support frames. What links them is the duty rather than the machine name — load: Combined radial + axial. If your installation is not on that list it matters less than you would think: the operating condition decides the specification. Send us the load, the speed, the running temperature and the environment it runs in, and we will match it to the right execution in the SKF range and confirm what is in stock.
Specify it against the duty.
Specification here follows the operating condition, not the catalogue. An inclined shaft feeds a steady downhill thrust into one support — The split tapered bearing at that end, with the thrust direction confirmed before ordering. Fitting it facing the wrong way puts the load on the small end of the rollers. Shaft position has to be held closely for coupling or seal alignment — This design set to a small end float rather than a floating cylindrical arrangement, which allows the shaft to wander under changing load. Duty involves start-stop loading with reversing thrust — An opposed arrangement across the two supports. A single tapered row cannot resist reversal, and the unloaded direction will let the rollers unseat and skew. Where two of those apply at once, specify for the harsher of the two — under-specifying is what puts the part back on the bench a month later. Send us the duty and we will confirm the execution.
Ordering this from SES.
Record the end float you set, on a tag inside the housing cover. Split tapered bearings are almost always reset by a different crew than the one that fitted them, and the second crew has no other reference to work from.
