产品介绍

NTN圆柱滚子轴承,作为恩梯恩(中国)投资有限公司的重要产品之一,以其只特的设计和可靠的性能广泛应用于各类机械设备中。该类轴承的滚动体为滚子,具有较高的载荷能力,并且内外圈可分离,使得安装过程简便快捷。NTN圆柱滚子轴承凭借其稳定性和耐用性,在众多工业领域中发挥着关键作用。滚动体为滚子,载荷能力较高。滚子由内圈或外圈的挡边引导。内外圈可分离,所以安装简便,内外圈都可以采用过盈配合安装。内外圈都有不带挡边的类型,沿轴向可以自由地移动,广泛用作于吸收轴膨胀的“自由端轴承”。对于带挡边的设计,滚子端面和挡边间可以承受微小的轴向载荷。HT型圆柱滚子轴承通过优化滚子端面形状及挡边形状的设计,提高了承受轴向载荷的能力。E型圆柱滚子轴承的内部特别设计提高了径向载荷能力。E型小径轴承已经成为标准设计。

产品特点

高载荷能力:滚子设计使得轴承能够承受较大的径向和轴向载荷,满足高负荷工况下的需求。

安装简便:内外圈可分离的设计,不仅便于安装,还允许内外圈均采用过盈配合安装,提高了装配的灵活性。

自由端轴承功能:部分型号的不带挡边设计,允许轴承沿轴向自由移动,有效吸收轴的膨胀,减少因热膨胀引起的应力。

轴向载荷能力:通过优化滚子端面和挡边的设计(如HT型),提高了轴承承受轴向载荷的能力。

径向载荷增强:E型圆柱滚子轴承的内部设计特别针对提高径向载荷能力进行了优化,使得小径轴承已成为标准设计。

常见型号

虽然具体型号未在参考链接中详细列出,但NTN圆柱滚子轴承大多数情况下包含多种型号,以满足不同尺寸、载荷和工况的需求。用户可根据实际应用场景和性能要求选择合适的型号。

工作原理

NTN圆柱滚子轴承的工作原理基于滚子在内外圈滚道之间的滚动。当轴承承受径向载荷时,滚子在滚道内滚动,将载荷均匀分布到整个接触区域,从而降低了接触应力,延长了轴承的使用寿命。与此同时,对于带挡边的设计,滚子端面与挡边之间还可以承受微小的轴向载荷。

应用行业

NTN圆柱滚子轴承由于其优异的性能和广泛的应用适应性,被广泛应用于多个工业领域,包括但不限于:

冶金行业:在轧机、连铸机等重型机械设备中,承受高温、重载工况。

矿山行业:在采矿机械、输送设备等中,适应恶劣的工作环境。

机械设备:作为各类机械设备的关键传动部件,确保设备的平稳运行和龑传动。

能源行业:在风力发电、水力发电等能源设备中,承受高速旋转和重载负荷。

交通运输:在轨道交通、汽车制造等领域,提供可靠的传动支持。

合理报价

关于NTN圆柱滚子轴承的具体报价,由于价格受多种因素(如材料成本、生产工艺、市场需求、型号规格等)影响,结果无法直接给出。建议用户通过NTN官方渠道或授权经销商进行询价,以获得准确的价格信息和专业的选购建议。在询价时,用户应提供详细的型号规格、数量以及交货期等要求,以便经销商给出合理的报价和交货方案。
