JDB-650固体镶嵌自润滑轴承:自润滑轴承产品类型，以铸造铜合金为基体,产品整体按一定比例镶嵌MoS2成分固体润滑剂的一种高性能自润滑产品。这种产品突破了一般轴承依靠油膜润滑的局限性,可以在无给油的工况下工作。在使用过程中，通过摩擦使固体润滑与轴摩擦，形成油、粉末并存润滑的优异条件，既保护轴不磨损，又使固体润滑特性永恒。具有硬度高,耐磨性高的特点.
推荐使用场合： 
这种结构综合了铜合金和润滑材料的各自特点，可以在难以形成油膜润滑和因条件限制而不能添加润滑剂的场合使用。基体含有的润滑材料一般贯通轴承内外径，设备在运转使用过程中，通过摩擦使润滑材料与轴相互摩擦，润滑材料和润滑油不断渗出，在轴承内壁和轴之间形成油膜润滑的优异条件，既保护轴不磨损，又使固体润滑特性持续永恒。可以用在低速重载不便维护，无给油的工况，并且在零下温度和零上300℃之间都可以使用。具有硬度高，负荷大、耐腐蚀、摩擦系数低的特点。以数控机床成品，对数量和尺寸几乎没有限制。产品一般运用在为避免污染而不能加油或处于封闭性结构内不易加油的场合；往复、摇摆运动、频繁启动、制动低速重载、短距离滑动以及处于水中或腐蚀性液体中难以形成润滑油膜的场合；作业环境恶劣，注油润滑效果难以发挥的场合；

Bronze bearing with solid 
modern-day bearing materials. Zero maintenance is often expected under severe to extreme conditions as well as under maximum loads.
The constant pressure on costs also calls for increasing uptime of machinery and equipment and uncompromising standards of operational reliability. materials are suitable for applications involving sustained high static and dynamic loads,relatively low sliding speeds and rotary, angular, axial or linear motion. They are also suitable for applications where conventional lubrication is not possible or permissible, or where other properties are required such as durability and resistance to operational and environmental or special conditions (e.g. impact load, abrasive stress, etc).
In conventionally lubricated bronze materials a?separating lubricating film“ can only be formed if themovement conditions and sliding speeds are suitable.With self-lubricating bearing, the lubrication is provided by thesliding material itself. The solid lubricant is released from the bearing material by micro abrasion as soon as thesliding movement begins. This gives the sliding partnerssmooth surfaces with a firmly adhesive solid lubricantfi lm. The solid lubricant remains within the contact zoneeven under heavy loads, resulting in a high degree ofseparation between the sliding surfaces and a sustainedlow coeffi cient of friction coupled with minimal wear.
现代轴承材料设计要求产品应用在零维护及预计经常在恶劣较端条件以及较大负荷下。成本压力不断加大的同时还要求机械设备增加正常运行时间，严格标准的运行可靠性，此型号产品的润滑材料全部集中在轴承的内径表面包裹旋转轴，既能较大限度的保留轴承的承载力又较大的满足了工况的润滑要求，材料适合应用涉及持续的高静态和动态负载。
能相对降低的滑动速度摩擦力，可以用于旋转，角度，轴向或直线运动。润滑是由提供滑动材料本身提供的，只要运转开始固体润滑剂就会通过微磨损的轴承材料来释放，润滑剂保持接触的区域内的甚至在重负载下，高性能的滑动表面和一个持续之间的分离低摩擦系数可以保证轴承的磨损量在非常小的范围内。
