The FAG HCM line covers super precision bearings built for setups where rotational accuracy and rigidity drive the result. Machine tool spindles, measuring instruments and high-speed systems are the usual homes for these bearings, which handle combined loads while keeping friction low. MR Industrial Accessories LLC supplies this series and helps buyers match the right variant to their application.

Reading an HCM part number is a matter of breaking it into blocks. The letters HCM mark the super precision family. The two digits that follow set the size and section, as seen in HCM7005, HCM7006 and HCM7007, where those figures relate to bore diameter. After that, EDLR covers internal design details such as cage type and preload, T signals dimensional heat treatment, P4S gives the precision class and XL identifies the optimized version. A reference like HCM7010-EDLR-T-P4S-XL therefore points to a size 10 super precision bearing with those particular characteristics.

Where do these bearings fit? Milling, grinding and machining center spindles rely on them when speed and accuracy cannot be compromised. Metrology equipment, precision drill heads and positioning systems also use them. The series runs at high speed while generating little heat, which suits continuous machining work and helps plants hold tight tolerances.

Selection comes down to a few variables: axial and radial load, top operating speed and lubrication method. The environment decides whether sealing or protective plates are needed, since contaminated areas call for a protected design. Preload and internal clearance follow from the application, and too much preload pushes temperatures up. Spindle alignment and mounting quality matter just as much, because poor fitting brings vibration. Grease or oil lubrication should follow the manufacturer's guidance for the given size and speed range.

Equivalents are a frequent question. Other super precision brands use similar designations, but the letters and digits rarely line up exactly, and interchangeability rests on main dimensions plus precision class. The reliable route is to quote with the full part number. If the number you have comes from another brand, we can point you to the matching FAG variant. Each suffix in the HCM series tells you something about how the bearing behaves.

Send the exact part number you need by WhatsApp, for example HCM7008-EDLR-T-P4S-XL, and we will respond promptly with options. If the designation is unclear, a photo or drawing helps us identify it. We can also advise on selection for your specific application.
