How to read SKF 21307 CCK
- 213Series
- Spherical roller bearings, 213 series. For the same bore, each series has a different outside diameter and width.
- 07Bore
- 35 mm bore: 07 × 5.
- CCKSuffix
- SKF suffix: it defines the variant (sealing, cage, internal clearance or other features).
21307 is the standard (ISO) basic designation: it defines the type, the series and the bore.
Description
The SKF 21307 CCK bearing has a 35 mm bore, a 80 mm outside diameter and a 21 mm width (35 x 80 x 21 mm).

SKF spherical roller bearings are self-aligning components with two rows of rollers, designed to support radial and axial loads in both directions, even with misaligned shafts. They are used in equipment where shaft deflection or mounting errors require self-aligning capability. MR Accesorios Industriales sells them in Buenos Aires, Argentina, and quotes them by WhatsApp.
The designation of these bearings combines a series number with letters that identify the execution. In the 213 series, for example, the codes 21306 CCK and 21307 CCK indicate the size: the series number 213 and the bore number (06 and 07) that defines the bore diameter. The CCK suffix is part of the code and distinguishes this variant within the spherical roller family. To order yours, send the complete code exactly as it appears on the drawing or on the equipment's identification plate.
These bearings are used in process industries, mining, cement, steel, paper, aggregate processing and material handling, where equipment operates with variable loads and shafts that deflect. They also appear in reducers, conveyor belts, mills, screens and agricultural machinery. In Argentina, MR Accesorios Industriales sells them along with a broad line of bearings, housings and power transmission for maintenance and replacement.
To select the correct bearing, take into account the radial and axial load, the rotation speed, the type of fit and the environmental conditions. Mounting must be done with suitable tools, without striking the rings, and verifying the alignment of the shaft with the housing. Lubrication and sealing are chosen according to the level of contamination and the working temperature. If the equipment allows misalignment, this type of bearing compensates for it without losing load capacity.
When replacing a bearing, it is common to find equivalent codes from other brands. Interchangeability is defined by the main dimensions (bore diameter, outside diameter and width) and by the type of execution. If you have the code from another brand or an unidentified part, write to us by WhatsApp: we'll indicate the equivalence compatible with your equipment and quote the exact code you need.
MR Accesorios Industriales has more than 80 years of experience in Buenos Aires, Argentina, and sells SKF bearings along with housings, seals, bushings, chains and pulleys. If you are looking for a spherical roller bearing, send the code or the size by WhatsApp and we'll quote it shortly.

Frequently Asked Questions
- What are the dimensions of the SKF 21307 CCK bearing?
- The SKF 21307 CCK bearing has a 35 mm bore, a 80 mm outside diameter and a 21 mm width (35 x 80 x 21 mm). These are the standardised boundary dimensions (ISO 15) of the basic designation 21307.
- What type of loads do spherical roller bearings support?
- They support radial and axial loads in both directions, even when the shaft is misaligned. Their two-row roller design compensates for deflection and mounting errors, which is why they are used in equipment with long shafts or subject to vibration.
- How do I request a quote for an SKF bearing?
- Write to us by WhatsApp with the complete code, for example
21306 CCKor21307 CCK, or with the bore size. We'll quote it shortly and indicate the compatible alternative if you bring the code from another brand. - What should I take into account when mounting a spherical roller bearing?
- Check the alignment of the shaft and the housing, use suitable mounting tools and avoid striking the rings. Lubrication and sealing are chosen according to the working environment. If the equipment allows misalignment, the bearing compensates for it without losing load capacity.
