Low noise
Oil-impregnated bearing material No.1-H
General-purpose copper type bearing material This is a soft material with low noise
Characteristics
This material is equivalent to JIS P4013Z. Because it is soft and works well with the shaft, it is perfect for acoustic applications and cameras and the like, where it is desired to avoid sliding noise from the motor. Further, it is a Cu-Sn type and is effective as a countermeasure for rust, which is a concern in Fe type materials.
Uses
- Camera and acoustic-related motors / Fan motors / Office equipment, such as multifunction printers
- Fishing equipment, such as electric reels
- Vehicle equipment, e.g. washer pumps
