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最好的,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。 耐高温塑料深沟球轴承尺寸表 外形尺寸(mm) 有关安装尺寸(mm) 重量 轴承型号 da da Da ra (kg) d D B r (最小) 最小 最大 最大 最大 (参考) P684 4 9 2.5 0.1 4.8 / 8.2 0.1 0.0001 P694 11 4 0.15 5.2 / 9.8 [...]

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,故此类抗酸碱塑料轴承不适用于较大负荷及较高转速,为克服此类抗酸碱塑料轴承的缺点。相比较而言,采用UPE材料则具备更佳的强度,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。这样抗酸碱轴承综合性能将会得到较大提高。 塑料深沟球轴承尺寸表 外形尺寸(mm) 有关安装尺寸(mm) 重量 轴承型号 da da Da ra (kg) d D B r (最小) 最小 最大 最大 最大 (参考) P684 4 9 2.5 0.1 4.8 / 8.2 0.1 0.0001 P694 11 4 0.15 5.2 / 9.8 [...]
Plastic ball bearings for units and plastic ball bearing units. The plastic ball bearing units specially have the performance of corrosion and wear resistance, reduce vibration and anti-bump, are free from the maintenance and so forth. Such is the most ideal solution of many difficult problem which have puzzled the industry field for hundreds years. [...]
PEEK/PI Plastic Bearings (High temperature application plastic bearings) As newly developing engineering plastic material, PEEK and PI have been approved have the strongest mechanical strength and could endure the highest temperature among all the plastic material. PEEK could work at 260℃ and PI at 300℃ in long-term. Moreover they have excellent.anti-corrosion performance could be used [...]
