Use a self-contained liquid bearing (Sealed Precision FDB). The bearing and the spindle are made of high quality compressed metal and are lubricated by a special oil film resistant to temperatures of up to 250C° / 480F°. This drastically reduces friction, ensuring smooth operation and reduced wear, which results in an average life-span of 120 000 hours. Included vibration- and shock absorbing rubber pads which cover the tunnelless mounting holes. These decouplers effectively eliminate possible vibrations and allow low-noise operation. High airflow with low noise contribution as quiet case fan Dimension: 120x120x15mm, MTTF: 120,000hours
