產(chǎn)品說明
SF-2Y邊界潤滑無鉛軸承,是在SF-2的基礎上改進而成。其性能與SF-2相同,但表面不含鉛,使用領域可以擴展至有要求的領域。目前該產(chǎn)品已應用于進口紡織設備、柱塞泵擺動部位、汽車操縱桿部位等中載、中速、油脂潤滑的場合。
技術參數(shù)

 

承載壓力:70N/mm2
適用溫度范圍:-40~+130攝氏度

 

滑動速度:2.5m/s
摩擦系數(shù):0.05~0.25
允許

 

PV值:2.8N/mm2 .m/s
允許

 

PV值:22N/mm2 .m/s
應用特點:
1.承載好,耐磨性能良好。
2.適用于高載低速下的旋轉(zhuǎn)運動、搖擺運動及經(jīng)常在載荷下啟閉頻繁而不易形成流體動力潤滑的場合。
3.在邊界潤滑條件下可長期不加油保養(yǎng),而在過層中加油使軸承使用壽命更長。
4.表面塑料層在加工成型時可留一定的余量,裝配壓入座孔后可自行加工,以達到更好的裝配尺寸。
5.產(chǎn)品主要運用于汽車底盤、冶金機械、礦山機械、水利機械、建筑機械、農(nóng)用機械、軋鋼設備等。
6.因其不含鉛,故可廣泛運用于無鉛領域。
