详细内容:产品基本信息: 型号:lectric B 42-72 英文名称:KLUBERlectric B 42-72 粘度等级:NLGI 品牌/产地:克鲁勃,德国 包装规格及价格:1KG/2400 25KG/58600 类型:导电滚动轴承润滑脂 宝贝描述: Klüberlectric B 42-72导电滚动轴承润滑脂 说明:Klüberlectric B 42-72是一个完全基于合成润滑脂酯油,合成烃油,专用锂皂,固体润滑剂。由于其特殊的组成,在静电滚动轴承进行通过油脂,从而防止当地电压放电哪严重损坏轴承滚道和滚动体。在除了导电属性,Klüberlectric B 42-72提供- 宽工作温度范围- 良好的防腐蚀保护,并- 使用寿命长。 应用:Klüberlectric B42-72已专为长期滚动轴承的润滑其中静电可能会发生,例如在电动马达,造纸复印机,机,薄膜拉伸支架和风扇。该润滑脂证明高效的应用受电动电流<1 A和特别是对球轴承。电导率的Klüberlectric B42-72已确定在DIN为基础的测试53482。在滚动轴承测试钻机FAG FE9,DIN51821,轴向负载为1.500 N,6.000转速,开一个安装位置,140℃,实现了产品的服务中生活>200小时失败,概率50%。 包装规格:1公斤可以25千克桶。 英文: Klüberlectric B 42-72 Electroconductive rolling bearing grease Description: Klüberlectric B 42-72 is a fully synthetic lubricating grease based on ester oil, synthetic hydrocarbon oil, special lithium soap and solid lubricants. Due to its special composition, static electricity in rolling bearings are conducted through the grease, thus preventing local voltage discharge which would severely damage the bearing raceways and rolling elements. In addition to the electroconductive properties, Klüberlectric B 42-72 offers – a wide service temperature range – good corrosion protection, and – a long service life. Application: Klüberlectric B 42-72 has been designed for the long-term lubrication of rolling bearings in which static electricity may occur, such as in electric motors, papermaking machines, copying machines, film-stretching stenters and fans. The grease has proven efficient for applications subject to electric currents < 1 A and especially for ball bearings. The electric conductivity of Klüberlectric B 42-72 has been determined in tests based on DIN 53 482. On the rolling bearing test rig FAG-FE9, DIN 51 821, axial load of 1,500 N, 6,000 rpm, open mounting position A, 140 °C, the product achieved a medium service life of > 200 h, failure probability 50%. Minimum shelf life: The minimum shelf life is approx. 36 months when stored in a dry place and in closed original containers.
