The SKF CARB bearing is a single row bearing with long, slightly crowned rollers. It combines two things that other types offer separately: it aligns itself like a spherical roller bearing and lets the shaft move lengthwise inside the bearing itself, like a cylindrical roller bearing. That is why it is used at the non-locating support of long shafts or shafts that expand with temperature.

All designations start with C. In C 2215 K, the digits give the dimension series and the size, following the same logic as spherical roller bearings; the K marks the tapered bore, for mounting on a sleeve. C 2216, without K, has a cylindrical bore.
More blocks may follow. C 2215 K/C3 is the previous base with a block after the slash, and C 2206 TN9 adds letters after the size. The line also includes versions with a V. Each combination is a different reference: copy the whole designation, with slashes and spaces.
On a shaft with two supports, one fixes the position and the other lets the shaft lengthen. The CARB goes in the second. Since the displacement takes place inside the bearing, the outer ring can stay firm in the housing. Keep this in mind when replacing a spherical roller bearing with a CARB, or the other way round: even when the main dimensions match, the housing arrangement changes.
The bearing accepts misalignment and displacement, but within limits that depend on clearance and size. When mounting it, the rings must sit in the relative position planned for the expected expansion. If the previous one failed at one end of the rollers, check that position before fitting the replacement.
Send us the complete designation and the quantity. State whether the bore is tapered or cylindrical and, if it sits on a sleeve, the sleeve designation and the shaft diameter. Tell us which machine it runs on, which bearing is at the other support and whether the housing is split. When it replaces a bearing of another type, give us both designations so the arrangement can be reviewed.
It can take its place at the non-locating support if the dimensions match, but the arrangement changes. Check it first.
It is not intended for that: it lets the shaft move. The other support takes the axial load.
A tapered bore. It is mounted on a sleeve or on a tapered seat on the shaft.

CARB roller bearings are self-aligning radial bearings with a single row of rollers, designed to support combined loads and compensate for angular misalignment. They are used in applications where shaft deflection or mounting errors require self-aligning capability, such as transmissions, pumps and process equipment. MR Accesorios Industriales supplies the SKF line with technical advice to select the correct part number.
CARB bearings are self-aligning toroidal roller bearings that combine the load capacity of roller bearings with the ability to compensate for misalignment. They are designed for applications where shaft deflection or alignment errors are unavoidable, such as in belt or chain drives. At MR Accesorios Industriales we supply the SKF line to provide robust solutions for Argentine industry.
Just the manufacturer part number is enough: we will quote it and provide dimensions and equivalents via WhatsApp or email.
