Copper-based oil-impregnated bearing material 'No.1-H' with excellent quietness

Peace-Lon's "No.1-H" is a general-purpose copper-based oil-impregnated bearing material suitable for reducing abnormal noise and vibration in motors. It is a sintered oil-impregnated bearing material primarily composed of copper (Cu) and tin (Sn), equivalent to JIS P4013Z. Its unique softness as a copper-based material and excellent conformability to the shaft suppress vibration and noise during sliding, supporting stable rotation.

Main Features of No.1-H

1．Excellent QuietnessThe soft copper-based material easily conforms to the shaft surface, which is expected to reduce vibration and abnormal noise generated during sliding.

2．Good Initial ConformabilityIt easily forms a stable sliding state from the early stages of operation, contributing to the reduction of abnormal noise risk in the initial phase.

3．Stable Self-Lubricating PerformanceBy impregnating lubricating oil into the fine pores within the sintered material, oil is supplied to the sliding surface during operation. It is also suitable for small motors where regular lubrication is difficult.

4．Excellent Corrosion ResistanceCompared to general iron-based oil-impregnated bearing materials, it is less prone to rust, making it suitable for high-humidity environments and applications requiring corrosion resistance.

5．Extensive Track Record of AdoptionIt can be adopted in various products, primarily small motors where quietness is emphasized.

Comparison with General Iron-Based Materials

※The optimal material varies depending on factors such as load, rotational speed, shaft material, operating temperature, lubrication conditions, and operating environment.

Main Applications

No.1-H is suitable for the following products that require quietness and stable rotation:

• Camera Motors
• FAN Motors
• Audio Equipment
• Office Automation Equipment
• Small Home Appliances
• Electric Reels
• Washer Pumps
• Various Small Precision Motors
