SKF Cooper Split Tapered Roller Bearings
Split tapered roller bearings from SKF Cooper combine the combined-load handling of a tapered roller bearing with the assembly convenience of a split design. They can support high radial loads and unidirectional axial loads, and are used in applications like crane wheels, winch drums, and mixer shafts where both load types are present and accessibility is limited. The bearing comprises a split cone (inner ring and rollers), split cup (outer ring), and split cage. Proper axial setting can be achieved during installation using shims, as with solid tapered bearings. SKF Cooper split tapers enable heavy equipment maintenance teams to replace thrust-supporting bearings without dismantling drive systems or removing heavy shafts, a process that otherwise would require extensive rigging and downtime.

Combined Radial and Axial Loads
Split design retains tapered geometry for thrust.
In-Situ Retrofit
Replace solid tapered bearings without removing shaft or couplings.
Adjustable Setting
Clearance or preload set during assembly via shims.
Robust, Sealed Design
Split seals and housing options for environmental protection.
Ideal for Crane and Winch Drums
High accessibility constraints make split tapers ideal.
Durable, Proven Materials
Case-hardened components withstand shock.
Replacing Solid Tapered Roller Bearings in Crane Wheels
Bridge crane wheel blocks often require complete disassembly to change a solid tapered bearing. SKF Cooper split tapered roller bearings allow replacement directly inside the wheel block, cutting repair time by 80% and reducing crane outage.
Setting Axial Clearance in Split Tapered Bearings
A shim pack between the housing and the bearing cup outer face adjusts the internal clearance. SKF provides detailed procedures to measure endplay with a feeler gauge and achieve the specified preload, ensuring the bearing runs without excessive heat or play.
