产品概述 Introduction
SF-4系列青铜卷制轴承套是我公司在SF-3钢-铜铅双金属轴套产品基础上开发设计的新一代轴套，该产品在国外应用十分普遍。随着我国引进机械设备的新机种日益增多，设计师们对新颖摩擦材料、轴套的要求也日益需要。因此该产品在我国机械制造集中有着宽广应用领域和实用价值。
SF-4系列轴套最大特点是薄壁结构，不占据很大的装配空间。轴套材料采用特殊配方高密度铜合金带材。它与传统的铸型铜套相比，具有密度高、无气缩孔、承载能力大，又有耐磨耐疲劳等优点。轴套制造采用先进的工装模具，可在带材摩擦面上加工出适应各种工况条件的油穴、油坑、油槽，从而使轴套在使用中可储存大量润滑油脂，延长加油间隔时间，有效地提高了使用寿命。SF-4系列轴承广泛应用于农业机械、建筑机械、工程机械、汽车行业等。
Thin wall thickness is the most important peculiarity of the SF-4 Bush series. They are light and compact, The inner-layer of the bush being a kind of high density copper alloy of special compositions, there is no hole and pit and provides higher load capacity and fatigue strength, in compare with traditional casting bronze bushes. It is manufactured by advanced technology and machines, various kinds of lubricating indentations or grooves may be readily provided on the sliding surface, and so the re-oiling period is remarkably prolonged and the service lift is accordingly prolonged. It’s used in agricultural machinery, construction machinery as well as engineering machinery etc.
