2、fler Group IndustrialHR 1351四点接触球轴承特性四点接触轴承是单列角接触球轴承，因此与双列设计相比，在轴向所需的空间相当小。轴承包含实体外圈、可分离内圈、滚珠和保持架组件，保持架由黄铜或聚酰胺材料制成。双半内圈可以容纳尽量多的滚珠。双半内圈是针对具体轴承匹配的，即使相同尺寸的轴承也不能与另一个轴承的双半内圈相互替换。带有滚珠与保持架组件的外圈可以和双半内圈分开安装。双向轴向承载能力由于轴承的滚道带有高的挡边，接触角为 35 和尽可能多的滚动体，四点接触球轴承的这种设计具有高的承载能力。能够承受大的双向轴向载荷和小的径向载荷。外圈上带定位槽或不带定位槽具有双向轴向承载能
3、力的四点接触球轴承经常与一个径向轴承组合使用，用作推力轴承且和轴承座有径向间隙。为了快速且可靠地定位，大尺寸的四点接触球轴承外圈有两个定位槽且相隔180。这些轴承带有后缀 N2。角度不对中的补偿内圈相对于外圈的可能的倾斜角与轴承载荷、工作游隙和轴承尺寸相关联，且可调心角度很小。因此四点接触球轴承不适合轴承座孔的不对中或由于轴挠曲造成的角度不对中。轴承套圈的倾斜会增加运转噪音，增大保持架的应力并对轴承寿命造成有害的影响。密封四点接触球轴承为开式设计。润滑它们没有初装润滑剂，可以采用脂润滑或油润滑。352HR 1Schaeffler Group Industrial四点接触球轴承工作温度带黄铜保持
4、架的四点接触球轴承适用的工作温度范围为30 C到+150 C。轴承外径超过 240 mm 的尺寸稳定温度可达+200 C。带玻璃纤维增强尼龙保持架轴承的最高工作温度达+120 C。保持架四点接触球轴承标准保持架，请见下表。带黄铜保持架的四点接触球轴承带有后缀 MPA。这种窗式保持架由外圈引导。玻璃纤维增强尼龙保持架带有后缀 TVP。检查保持架材料聚酰胺对合成油脂以及带 EP 极压添加剂的润滑剂的耐化学性能。在高温下，老化的润滑油和油中的添加剂会降低塑料保持架的运转寿命。必须遵照润滑油的更换周期。保持架和内径代码1)通过协商可供应其它形式保持架。这些具有特殊设计保持架的轴承的高温高速适应性、基本
