FAG super precision bearings of the HCB series are components designed for high accuracy requirements, intended for machine tool spindles and equipment where repeatability is critical. MR Accesorios Industriales sells this line, with technical advice so you choose the right suffix and mounting. If you have the bearing part number, we'll quote it by WhatsApp shortly.

The designation of this series is read in blocks. HCB identifies the super precision family; the four-digit number indicates the bearing size. Then come the suffixes: CDLR defines the internal design and contact arrangement, T refers to the treatment or variant of the assembly, and P4S indicates the super precision tolerance class. Each block changes the bearing's behavior, so it's best to read the full part number before ordering.

These bearings are used in milling machine, grinding machine and machining center spindles, in measuring heads and in high speed equipment where rotational error must be minimal. In Argentina they appear in precision machining shops, machine tool factories, automotive plants and in the aeronautical sector. They are also chosen in instrumentation applications and in shafts that rotate at high speeds with rigidity and accuracy requirements.

To select correctly, you must look at the tolerance class, the type of sealing or its absence, and the internal clearance required by the application. Mounting a super precision bearing demands extreme cleanliness, careful alignment and lubrication suited to the working speed. Preload and tightening torque adjustment directly influence service life. If the spindle runs at high revolutions, it's advisable to check the lubrication and cooling of the assembly.

As for equivalences, super precision bearings are compared between manufacturers by dimensions, tolerance class and design type, but suffixes are not automatically interchangeable. The same size may have different clearance, sealing or load capacity depending on the brand. Therefore, before replacing a bearing, it's advisable to verify the full part number and the working conditions. At MR Accesorios Industriales we help you interpret those differences.

If you already have the bearing part number, send it by WhatsApp to MR Accesorios Industriales and we'll send you the quote shortly. If you're not sure which suffix you need, tell us what equipment it's mounted on and at what speed it runs, and we'll guide you to choose the correct variant within the series.
