FAG HCN super precision bearings are built for spindle and shaft positions where rotational accuracy and rigidity drive the result. Tolerances are held very tight, and the assemblies they sit in run at high speed under combined loads with repeatability demands. MR Industrial Accessories LLC supplies these bearings and quotes them by part number, matching the configuration each application calls for.

The part number breaks into blocks you can read one at a time. HCN marks the super precision series, and the digits that follow give the size inside that series. A K in the designation means the bore is tapered, while the PVPA block and its trailing number set the cage type and the precision level of the assembly. The SP suffix identifies the high accuracy class. Change any one of those blocks and you have a different variant of the same family.

Typical installations include machine tool spindles, grinding heads, boring machines, machining centers, and the high-speed shafts found in measuring and testing equipment. They also go into setups where dimensional repeatability cannot drift, such as internal and external grinders or high-speed milling heads.

Choosing the right variant starts with three inputs: shaft diameter, fit type, and mounting arrangement. On K versions the tapered bore seats on a tapered shaft and is held with a lock nut or adapter sleeve, which is how clearance or preload gets adjusted. Lubrication, housing cleanliness and support alignment all matter if rotational accuracy is to hold up over time. Follow the mounting procedure and check preload before the equipment goes into service.

When replacing a super precision bearing with another brand, match by dimensional designation and accuracy class rather than by the full part number. Cage, preload and tolerance suffixes differ from one maker to the next, so a true equivalence means comparing those parameters, not just the size number. If the replacement comes from a different source, validate the arrangement, the fit and the precision level before mounting. Our team can walk you through that comparison.

For any HCN variant, send the complete part number through WhatsApp or email, along with the equipment and the fit involved. With that information we confirm the configuration and return your quote promptly.
