SKF angular contact bearings in the CD/P4ATBTB series are precision sets with four rows arranged in tandem, back-to-back. They are used in machine tool spindles and applications where axial and radial loads are combined with high rigidity and speed. MR Accesorios Industriales carries this line as an official brand and advises you so you choose the correct set for your assembly.

The designation is read in parts. CD indicates the angular contact design with a 15° contact angle and larger balls for greater capacity. P4A is the dimensional and rotational precision class, higher than P4. TBTB describes the arrangement: four bearings in tandem, back-to-back, tandem, back-to-back. The examples 7013 CD/P4ATBTB, 7015 CD/P4ATBTB, 7017 CD/P4ATBTB and 7028 CD/P4ATBTB share that structure and vary in bore diameter.

These sets are used in milling machine spindles, grinding machines, machining centers and high-speed heads. Also in lathe chucks, precision grinding machine spindles and metrology equipment. In Argentina they are used by the metalworking, automotive, aeronautical and machine tool industries, where spindle repeatability and rigidity are critical for part quality and tool life.

To select, take into account the combined axial and radial load, the maximum speed and the required rigidity. Assembly requires cleanliness, alignment of the shaft and housing, and controlled preload. Lubrication can be grease or oil depending on the speed; sealing is defined by the environment. Respect the tightening torque and the adjustment order of the nuts so as not to deform the rings.

As for equivalents, precision angular contact bearings are interchanged between manufacturers by designation, precision class and arrangement, but always verify contact angle, preload and tolerances. Do not replace a P4A set with a lower class one if the spindle demands high accuracy. Consult drawings or samples to confirm interchangeability before mounting.

If you have the set part number or the spindle drawing, send it by WhatsApp to MR Accesorios Industriales. We quote the CD/P4ATBTB series and help you validate the arrangement, precision class and assembly. We have more than 80 years in the business and we know the demands of Argentine industry.
