NSK Machine Tool Ball Screw W2807SA-2Z-C5Z5 2805 Small Lead Ball Screw

The NSK W2802SA-1P-C5Z5 is a high-precision SA-type ground ball screw from the NSK A series, primarily used in precision industrial machinery, CNC machine tools, and automation systems requiring precise, repeatable, and heavy-duty motion control.

The NSK SA-type shaft-end finished product is a high-precision, standard ball screw designed by NSK Japan specifically for machine tool and heavy equipment feed systems.

Features of NSK SA type W2807SA-2Z-C5Z5 ball screw for machine tools:

Excellent precision: Standard C5 grade precision, with a preload structure achieving zero backlash, high positioning and repeatability accuracy, meeting the precision machining requirements of machine tools.

Sufficient rigidity: Optimized raceway structure and flange nut design provide strong load-bearing capacity and impact resistance, suitable for heavy-duty feed axis operations in small and medium-sized machine tools.

Easy installation: The ball screw shaft end is prefabricated, requiring no secondary processing, and can be directly matched with NSK standard support units, making assembly and equipment replacement simple and efficient.

SA-type lead screws are ideal for equipment with comprehensive requirements for positioning accuracy, installation speed, and space constraints:

CNC machine tools: X/Y/Z axis feed systems for small machining centers, CNC lathes, engraving and milling machines, and grinding machines.

Precision instruments: Measuring equipment, semiconductor manufacturing equipment, and industrial robotic arms.
