Why FAG’s HCM machine tool bearings?

Machining a part on a CNC which uses HCM machine tool bearings.

In the specialized world of machine tool spindle repair, downtime disrupts productivity and profit for machine shops. Optimizing precision and efficiency in your shop translates to improved machine running outcomes and more money. If time is money, then using the right bearings is golden. Schaeffler FAG HCM-series bearings are a great choice to help you improve efficiency.   

Key features

  1. Looking to increase your motor spindles’ load-carrying capacity for speed, forces, and temperatures? Schaeffler FAG’s HCM-series spindle bearings deliver.  
  2. The HCM-series bearings come with FAG’s “X-Life”, indicating ultra-high performance compared to other bearings with the same design envelope, even under challenging conditions. The precision structure delivers high operating and limiting speeds, combining robustness with performance.   

Schaeffler has combined the high-speed capacity of small ball bearings with the strength and load capacity of large ball bearings. You can increase the load-carrying capacity of your motor spindles with the HCM-series. A sturdy structure ensures the series can effectively withstand radial and axial loads. Quality materials mean a longer bearing life.  

Highest quality materials

HCM-series bearings combine a larger ball than the predecessor HC-series. The HCM-series has a 17-degree contact angle compared to the HC series 15-degree contact angle. This allows the bearings to handle a larger load without sacrificing speed capability.


The series offers temperature-resistant ceramic balls and races made from 100Cr6 rolling bearing steel with next-level X-life quality. These mean less friction and less thermal expansion with greater resistance to temperature gradients at high speeds. 

High performance

Precision bearings translate into smoother, longer operations, reduce stress on machines, and increase productivity. HCM-series spindle bearings mean longer running times, lower maintenance and unit costs, and high productivity for you.     

Expert assistance and quick shipping
