SKF Cooper Split Bearing Units
SKF Cooper split bearing units are fully integrated, ready-to-mount assemblies combining a split bearing (spherical, cylindrical, or tapered roller) with a split housing, split seals, and shaft locking. The complete unit is designed around the principle of in-place bearing replacement — assemble the bearing and housing around the shaft without removing couplings, gearboxes, or the shaft itself. This slashes installation and replacement downtime by up to 80% compared to solid bearings. Units are used in mission-critical applications where downtime is extremely costly: ship propulsion shafts, mine conveyors, large ventilation fans, and process machinery. SKF Cooper units deliver load ratings comparable to solid bearings and are manufactured with precision to ensure reliable operation. The complete unit simplifies procurement, providing a single part number for the entire assembly, with full technical support available from SKF.

Complete Split Assembly
Bearing, housing, seals, and locking all split for easy assembly.
Massive Downtime Reduction
Split design eliminates shaft removal — dramatically shortens planned maintenance windows.
No Shaft Removal Required
Ideal for coupled shafts, flanged shafts, or long shafts.
Load Ratings Match Solid Bearings
Near-equivalent dynamic capacity despite split design.
Custom Seal Solutions
Split seals tailored to dust, water, or chemical environments.
Global Engineering Support
SKF assists with unit selection and on-site installation training.
Cooper Split Units in Marine Propulsion Shaft Lines
Propeller shafts are supported by multiple bearings; replacing one normally requires dry-docking. A SKF Cooper split unit can be assembled underwater or in a confined engine room, allowing at-sea or alongside bearing renewal that keeps the vessel in service and eliminates dry-dock expense.
Cost-Benefit Analysis: Solid vs. Split Bearing Units
While a split unit has a higher initial cost, the reduction in downtime, crane time, and labour more than compensates in critical processes. For a 24/7 mine conveyor losing $20,000 per hour, the one-day downtime saving pays for the unit many times over in a single replacement event.
