尼龙防脱垫片 retaining washer
主要起到定位和防脱之功能。亦可用于光滑的圆轴。
止动垫圈、定位防脱垫圈，塑料内齿垫圈
材料说明：
尼龙66（PA 6/66），标准颜色为米白色。
用于螺钉的预组装，无损失脱落风险，以降低最终组装成本。
尼龙防脱垫圈部件具有良好的电气绝缘性，无锈蚀问题。
由于其内部独特的内齿设计，这些防脱垫圈可以轻松咬合抓住螺纹，因此使得螺钉不会从机械设备(柜门面板及壳体）上滑脱。
便于组装，并吸收振动。
提供公制（库存品）和英制尺寸（这些尺寸中的大多数都有库存）。
止动垫圈，也称为推入式螺母，可夹紧螺栓、螺钉和轴组件的外部，形成紧密配合，防止转动松开脱离。
ALW系列尼龙防脱垫片(retaining washer)有39个不同的规格型号。可以配套卡套在M2-M24及英制全系列螺杆的外螺纹上，防止紧固件从设备上散落遗失。主要起到定位和防脱之功能。亦可用于光滑的圆轴。

关于信诺华工业RTW内齿定位防脱垫圈选型的小提示：
如果定位防脱垫圈是应用于外螺纹紧固件，那么咱们通常需要先确定或者测量一下外螺纹的直径，通常来说，防脱垫圈的咬合齿最内侧直径径(最小处内径)d2要稍微小于螺杆直径这样才能有效卡紧定位，同时无齿处内径d1又需要稍微比螺杆直径大一些以便螺钉能正常穿过。如果这些定位防脱垫片是应用于无螺纹轴，其选型原理亦同。如您有任何问题建议您随时联络我们的产品应用工程师或者索取免费样品试装。
Nylon Anti Loss/Retaining Washers
Technical Notes
Material of these Retaining Washers:
Nylon 66 (PA 6/66), standard colour is off-white.
Used for pre-assembly of screws and washers, with no risk of loss, to reduce final assembly cost.
Many Nylon parts are available in dyed black, this subject to a minimum value and process charge, please contact us for further details.Dyed black colour is not long term UV stable. Nylon parts offer good electrical insulation, is resistant to corrosion and most dilute acids.
Nylon protects work surfaces and absorbs shocks and vibrations.
Flat Anti Loss Washers are used for the preliminary mounting of Screws and Bolts with no risk of loss as their infernal serrated hole grabs the thread.
The ALW Anti-Loss Washers from Sinohua provide full insulation, cushioning and spacing.Insulate against moisture and electricity.
Allows ease of assembly and vibrations are absorbed.
Available in both Metric (Stock Line) and Imperial Sizes (most of these sizes are stocked).
Retaining washers, also known as push nuts, grip the outside of bolts, screws, and shaft components, creating a tight fit that prevents turning and loosening.
