HQW Precision’s premium, high-quality bearings shine in more than one context. From lathes and CNC mills to printing machines, machine tool spindle bearings are essential components for the machines that shape our world. That’s why finding the right bearings for them is so important. At Alpine, we carry HQW’s machine tool spindle bearings because of their phenomenal price-to-performance ratio and precise German engineering.

HQW first opened as a bearing service and customization shop in 2009 in Veitshöchheim, Germany. In 2013, they expanded to a facility in Kürnach to produce their own high-precision stainless steel bearings.

HQW is serious about production quality and consistency. The company’s bearings comply with international ISO 492 and national DIN 620 standards and meet American ABEC tolerance classes.

HQW manufactures machine tool spindle bearings up to ABEC 9 Class 2 grade. The balls inside are Grade 5 or higher. HQW uses the material S30V, a high-end stainless steel which is wear- and corrosion-resistant. This steel and its heat treatment makes HQW’s bearings remarkably long-lasting and suitable for extremely high speeds.
