The 9316 2.0 inch (50.8 mm) Adjustment Screw provides smooth, wobble-free adjustment combined with exceptional long-term stability and low susceptibility to thermal variation. It is the same 1/4-80 precision screw used in our optic mounts and allows you to build your own mounts or positioners. In addition to a travel of 2.0 inch (50.8 mm); the screw has a ball tip, unbraked brass bushing, and is knob adjusted. Outstanding positional and thermal performance is achieved using a proprietary assembly process. This assembly process uses tightly toleranced subcomponents and the ideal amount of lubrication. The small amount of lubrication is optimized to mitigate the effects of hysteresis and long-term creep caused by lubricant migration.



Our proprietary assembly process uses very tight tolerances and allows us to use very little grease. We limit the amount of grease because over time, and as the temperature varies, large amounts of grease can cause the threads to migrate, leading to hysteresis as well as long-term creep. The result of our proprietary process is actuators that have very smooth, wobble-free movement, high precision, and exceptional long-term and thermal stability.

9316 2.0英寸(50.8 mm)调节螺丝提供平滑、无抖动的调节功能，同时具有优异的长期稳定性和较低的热变化敏感性。这是相同的1/4-80精密螺丝用于我们的光学支架，并允许您建立自己的支架或定位器。除行程2.0英寸(50.8 mm)外;该螺丝有一个球头，未刹车的黄铜衬套，和旋钮调整。优异的定位和热性能是通过专有的组装工艺实现的。这个装配过程使用紧密耐受的子部件和理想的润滑量。对少量润滑进行优化，以减轻润滑油运移引起的迟滞和长期蠕变的影响。

我们专有的装配工艺使用非常严格的公差，允许我们使用非常少的油脂。我们限制油脂的数量是因为随着时间的推移，随着温度的变化，大量的油脂会导致线程迁移，导致滞后和长期蠕变。我们的专利工艺的结果是执行机构具有非常平滑，不摇摆的运动，高精度，和卓越的长期和热稳定性。
