• intros：{"brand_intro":"THK（蒂业技凯）成立于1971年，总部位于日本东京，是全球直线运动系统（LM导轨、滚珠丝杠）的发明者和领导者。创始人寺町彰博以'消除摩擦'为理念，首创了滚动接触式直线导轨。THK的凸轮随动器继承了其精密滚动技术，采用独特的'Caged Ball'保持器设计，减少摩擦发热。品牌在汽车、半导体、医疗设备领域占据高端市场，品控标准通过ISO 9001和IATF 16949认证，产品寿命测试标准严于JIS行业标准30%。","product_intro":"THK CF12-1B凸轮随动器定位为'免维护型'，核心卖点：内置润滑脂嘴（1B），可定期加注油脂延长寿命；外圈采用高碳铬轴承钢（SUJ2）并经过低温回火处理，抗冲击性强。适用于重型冲压机械、注塑机顶出机构、矿山振动筛等重载低速场景。与IKO相比，THK的润滑设计更灵活，但极限转速略低（6000rpm），更适合冲击载荷环境。","key_specs":{"外径":"32mm，壁厚加强设计","润滑方式":"脂润滑嘴（1B），支持外部加脂","动载荷":"12.5kN，抗冲击能力突出","适用温度":"-20°C至+120°C，耐高温","保持器材质":"钢制保持器，避免塑料老化问题"}}
