FB09G solid embedded bronze rolled bearings are made of bronze material as the substrate, with special solid lubricants embedded on the surface. Due to the use of copper alloy material with high elongation as the substrate, ultra-thin rolled shaft sleeves can be made, and the ideal filling material is wear-resistant. Therefore, they are suitable for use as wear-resistant shaft sleeves in automotive transmission shafts, and can also be used in other situations without oil lubrication.

APPLICATION CHARACTER
1. No or insufficient oil lubrication
2. High load, low speed, high performance, superior to other bearings at medium speed
3. Suitable for areas where the formation of oil films is difficult, with frequent starting and stopping of reciprocating and swinging movements
4. During operation, a lubricating pad can be formed to transfer and protect against friction, without any biting or turning phenomenon, and to increase lubrication
5. Can reduce mechanical vibration, reduce noise, prevent environmental pollution, and reduce machine maintenance frequency
6. Thin walled structure, lightweight, can reduce mechanical volume, and save costs compared to the price of JDB-650 shaft sleeve
7. Especially suitable for situations with high temperatures, inability to refuel, and extremely difficult refueling
8. This product has been applied in automotive starting motors, elevators, cranes, and metal processing machinery, etc
