1.精密塑料轴承 POM和PA材料具备良好的机械强度及耐磨性,适合制作比较精密的塑料轴承,其良好的自润滑性能及低的磨擦系数,在保持塑料轴承传统优势的基础上,可应用于精密及较高转速运转。其中POM塑料轴承是所有塑料轴承中应用广泛的一种,一般内外球材料采用POM或PA,保持架采用玻璃纤维增强的尼龙66(GRPA66—25)。滚珠为玻璃球,不锈钢球或陶瓷球,此种轴承碱性环境下表现良好但不适合在酸性腐蚀环境下运行。 2.耐腐蚀塑料轴承 作为氟塑料中典型的品种,PTFE和PVDF是具有优良的耐腐蚀性能,其中PTFE更是所有已知工程塑料中耐腐蚀性较好的,可用于所有的浓酸及浓碱场合,包括HF及发烟硫酸硝酸(98%以上)等,且具有良好的高温表现,PTFE证明可用于180℃ 的高温,PVDF也能用到150℃ ,但PTEF材料机械强度极低,且尺寸稳定性较差,温度变形大,相比较而言PVDF具有更佳的综合性能,一般内外圈材料选用PTFE或PVDF,保持架材料为PTFE或PVDF,滚珠一般为玻璃球或陶瓷球。 3.抗酸碱塑料轴承 HDPE、PP、UPE材料已证明能用于相对较弱的酸碱交叉环境(30%Cucl2溶液和30%NaoH溶液测试OK)故适用于大多数酸/碱/盐/溶济/油/气体及海水腐蚀环境。具备一般塑料轴承之无油自润滑,抗磁电绝缘等性能,但机械强度较低,容易变形,故不适用于较大负荷及较高转速,相比较而言,UPE材料具备更佳的强度,低磨擦特性及低温应用特性(最低可至- 150℃ ),一般内外圈材料采用HDPE、PP或UPE,保持架材料采用HDPE、PP或UPE,滚珠为玻璃球、不锈钢球或陶瓷球。 4.PEEK/PI塑料轴承(耐高温塑料轴承) PEEK和PI作为新兴的工程塑料材料,被证明是所有已知工程塑料中机械强度尺寸稳定性及耐高温性能较好的,其中PEEK长期使用温度达 260℃ ,PI长期使用温度更是高达300℃ ,且其具有优良的耐腐蚀性能,在中等强度的酸碱腐蚀环境仍可以运转自如,故一般用于制作需要在比较严酷环境中精密运转的轴承,其缺点是因材料本身比较昂贵,故使用成本较高,一般内外圈材料选用PEEK或PI,保持架材料为PTFE,PEEK或PI,滚珠一般为Zro2或Si3N4陶瓷球。 5.塑料轴承座及塑料外球面轴承 塑料带座轴承独具重量轻,安装简便,免于维护,同时具有常用铸铁座或冲压座所不具有减震抗冲击性能。随着新材料的不断开发正越来越多地在工程上得到广泛应用。针对不同情况,塑料外球面轴承可采用POM,HDPE,PP,UPE,PTFE等不同材料制作,塑料轴承座一般采用PBT材料。
