The 624 Z High Precision Bearing is engineered for medical-grade applications, delivering ultra-smooth, low-noise, and contamination-free performance. Designed for surgical tools, dental handpieces, imaging devices, and lab equipment, this bearing features stainless steel construction (SUS440C/SUS316) for corrosion resistance and ceramic hybrid options for non-magnetic requirements.
With ABEC-5 or higher precision grades, it ensures minimal vibration and friction, critical for sensitive medical instruments. The Z-type single metal shield protects against particulate ingress while maintaining lubrication integrity in sterile environments.
