NORBERT NBU 15 高速主轴轴承润滑脂

文档摘要

作为一款专为极端高速与高精度工况设计的润滑解决方案,NBU 15通过其独特的配方与验证性能,致力于解决高速轴承系统的润滑挑战,延长设备寿命,提升运行可靠性,并最终为用户降低总持有成本。


1. 引言:高速时代的润滑挑战

随着现代制造业向高转速、高精度、高效率方向持续发展,机床主轴、纺织机械、精密传动系统等设备中的轴承正面临着日益严苛的运行条件。高速运转带来的温升、离心力、微动磨损,以及来自冷却液、金属屑等多介质环境,对润滑脂的性能提出了全方位挑战。传统润滑脂往往在高温下流失、氧化,或在高速下被甩出,导致润滑失效、轴承磨损加剧,进而引发设备停机与高昂维护成本。

NORBERT NBU 15的研发,正是为了直面这些挑战。它不仅仅是一种润滑脂,更是一套经过实践验证的高速轴承系统保护方案。

2. 产品核心特性与技术解析

2.1 专为高速而生

  • 卓越的高速保持性:其独特的均匀短纤维状结构,结合优化的增稠剂与基础油体系,使其在高达1,600,000 mm/min的速度因子(n x dm) 下,仍能牢固地附着在轴承滚道内,抵抗离心力作用,避免润滑失效。

  • 优异的温控表现:精选的合成油与酯类油复合基础油,在高速剪切下粘度稳定,能有效降低轴承运转中的摩擦与温升,从而保护轴承钢材的金相组织与尺寸稳定性。

2.2 极致的防护性能

  • 复合钡基增稠剂系统:赋予产品出色的抗腐蚀、耐水性和耐介质性。即使在潮湿或接触切削液的环境下,也能在金属表面形成持久保护膜,SKF-EMCOR测试结果(腐蚀等级≤1)证明了其卓越的抗腐蚀能力。

  • 宽泛的温度适应性:工作温度横跨-40℃ 至 230℃,滴点高达280℃以上,确保了在严寒启动或高温持续运行的极端条件下,润滑脂结构不发生坍塌或严重硬化。

2.3 长效与可靠的润滑保障

  • 优化的抗磨与极压性能:特殊的添加剂配方提供了出色的抗负载能力,即使在重载或冲击载荷下,也能有效防止轴承滚道与滚动体的磨损,显著延长轴承使用寿命。

  • 优异的抗氧化性:有效延缓基础油在高温下的氧化进程,防止酸性物质生成,确保润滑脂在长期使用中性能稳定,最长保质期达36个月。

3. 典型应用领域

NORBERT NBU 15是以下高速、精密设备轴承润滑的理想选择:

  • 高速机床主轴:加工中心、数控铣床、精密车床的主轴轴承。

  • 纺织机械:高速纺纱锭子、络筒机、织布机的主轴及滚动轴承。

  • 精密传动系统:高速滚珠丝杠支撑轴承、直线导轨滑块、精密齿轮副(如斜齿轮)。

  • 其他高速设备:高速电机轴承、精密仪器主轴、电动阀门制动器等高转速部件。
