NLS4系列線性滑軌提供XY和XYZ配置。NLS4線性平臺的真空兼容版本在尺寸上與標準NLS4相同。NLS4真空定位平臺的每個部分都經過修改,以最小化虛擬泄漏和氣體釋放。所有鋁部件均經過透明銥處理,軸承使用Braycote 601EF潤滑脂潤滑,所有電線均采用特氟龍絕緣。步進電機和限位開關專為真空應用設計。緊固件采用不銹鋼制成,并在盲孔中通風,以消除虛擬泄漏。驅動系統采用不銹鋼ACME絲杠和乙縮醛塑料驅動螺母。驅動螺母提供零間隙操作,能夠自動調整磨損,以確保在整個平臺使用壽命內保持零間隙。使用線性導軌軸承可提供平穩的運動、高負載能力和剛性。由于滑塊在整個行程中得到支撐,因此可以實現良好的懸臂負載能力。電機和信號線長0.6米(24英寸),并配有DB-9連接器。請注意,DB-9連接器不兼容真空環境。
