This specification follows DIN (Deutsches Institut für Normung, German Industrial Standard). It is essential when maintaining German or European-sourced equipment and when supplying to the European market.
装在轴槽中防止零件轴向移动的C形卡簧。固定轴承、齿轮和皮带轮的轴向位置，用卡簧钳拆装。
实务注意事项
- 使用专用外卡簧钳。普通钳子会使卡簧变形，降低保持力。
- 确认轴槽深度和倒角。槽浅会导致卡簧弹出；无倒角则难以装入。
主要特点
- C型卡簧安装在轴槽中防止零件轴向位移
- 用专用卡簧钳安装和拆卸；可反复使用
- KS B 1336 / DIN 471 / ISO 5425；覆盖轴径8–100 mm
主要应用领域
齿轮箱轴承固定、电机轴零件定位、减速器内部装配、链轮/皮带轮固定
常见问题
轴用挡圈DIN 471和JIS B 2804有什么区别？
尺寸几乎相同但可能存在轻微厚度/槽深差异。互换使用时务必对比详细尺寸。
