CARB bearings are self-aligning toroidal roller bearings, designed to accommodate angular misalignment between shaft and housing without losing load capacity. They are used in applications where shaft deflection or mounting errors require tolerance. MR Accesorios Industriales supplies the SKF brand, with more than 80 years of experience in the field, and advises you to choose the correct part number for your equipment.
The CARB series designation is read in blocks. The initial letter C identifies the toroidal roller family. The first number indicates the dimension series. The letter K indicates that the bore is tapered. The number following the K is the taper angle. The slash separates the radial internal clearance class, which can be C2, C3, C4 or C5. For example, in C 4032 K30/C4: C is the family, 4032 the size series, K30 the tapered bore with 1:30 angle, and C4 the increased radial clearance. Learn more about this nomenclature by consulting MR.
These bearings are used in industries where shafts suffer deflection or misalignment, such as mills, conveyor belts, paper machines, mining equipment and cranes. In Argentina, they are common in cement plants, oilseed plants and the metalworking sector. Their self-aligning capability reduces wear and extends service life in demanding assemblies. As they do not require additional spherical housings, they simplify design and maintenance.
To select a CARB, take into account radial and axial load, speed, and the appropriate internal clearance. The tapered bore requires an adapter sleeve and a lock nut, with a fit that ensures correct interference. Lubrication can be grease or oil, and sealing must be chosen according to the environment: dust, humidity or temperature. Initial alignment is less critical than in rigid bearings, but it is advisable to verify the parallelism of the supports.
Regarding equivalences, SKF CARB bearings can be interchanged with other brands offering self-aligning toroidal roller designs, provided dimensions, tolerances and clearance match. There is no universal code correspondence, so it is essential to verify the complete designation. MR Accesorios Industriales supplies SKF as an official brand and can guide you on compatible alternatives for your application.

Frequently Asked Questions
- What does the K30 suffix mean in a CARB bearing?
- The K indicates a tapered bore and the number 30 specifies the taper angle, in this case 1:30. This allows mounting with a sleeve and nut to achieve the necessary fit. It is important to respect the angle when choosing the sleeve.
- How do I choose the right radial clearance for my application?
- Radial clearance depends on operating temperature, speed and fit. A C3 or C4 clearance is common in applications with heating. Consult MR to define the optimal clearance for your equipment and operating conditions.
- Are SKF CARB bearings interchangeable with other brands?
- They can be interchangeable with self-aligning toroidal roller bearings from other brands, if dimensions, tolerances and clearance match. There is no universal code equivalence, so the complete designation must always be verified before replacing.
