CARB Toroidal Roller Bearings for Non-Locating Bearing Positions
CARB toroidal roller bearings are specialised self-aligning roller bearings designed to carry radial load while accommodating axial displacement within the bearing. They are used in the non-locating position of a correctly designed bearing arrangement, where thermal movement, shaft expansion or deflection must be accommodated without imposing unwanted axial force on the system.
This collection contains 191 SKF CARB references. Live product titles identify C, C22, C23, C3 and tapered-bore variants where applicable. A matching bore alone does not establish a safe substitute: the complete designation and the equipment’s locating strategy must agree.
How CARB bearings differ from other roller bearings
CARB bearings combine self-alignment with internal axial displacement. That role is different from a locating bearing and should be selected as part of the complete shaft arrangement. Do not replace a spherical or cylindrical roller bearing solely by dimensions; confirm the original bearing position, axial-location method, load direction, housing fit, speed, lubricant and operating temperature.
For alternatives within the bearing system, compare Spherical Roller Bearings, Cylindrical Roller Bearings and Plummer Block Housings.
Read the designation before ordering
Record the full code on the existing bearing, including every prefix and suffix. Check bore, outside diameter, width, radial internal clearance, cage configuration, seal arrangement and cylindrical or tapered bore. Product titles in this collection include examples such as C2212TN9, C2318K/C3 and C4122V/C3; each suffix can affect the selected bearing or its operating clearance.
Where a sleeve-mounted bore is specified, verify the sleeve, locknut and lock-washer arrangement rather than assuming these components are included. View Sleeves and Locknuts & Washers when checking the complete mounting hardware.
Installation and condition checks
Inspect the shaft, housing seat, seals and lubrication system before fitting a replacement. Follow the bearing and equipment manufacturer’s mounting method, lubricant specification, quantity and relubrication interval. After commissioning, monitor temperature, vibration and noise; these observations can help identify alignment, fit or contamination issues before they damage the assembly.

CARB Toroidal Roller Bearing FAQs
Can a CARB bearing replace any spherical roller bearing?
No. CARB bearings have a particular role in a locating/non-locating arrangement. Confirm the original design, full designation and manufacturer requirements before changing a bearing type.
Does a CARB bearing carry axial load?
Its role is to accommodate axial displacement while carrying radial load. The complete bearing arrangement determines how axial forces are controlled, so check the equipment design before selecting a replacement.
What information is needed to match a CARB bearing?
Provide the complete existing code, bore type, dimensions, clearance or suffix details, housing arrangement and application. This gives the strongest basis for comparing listed product options against the equipment specification.
