The NSK KA series ball screw turns rotary input into axial movement with high efficiency and repeatability. It suits machine tools, automation equipment, and positioning systems that call for precision and rigidity. MR Industrial Accessories supplies this line and assists with selection for your application.

The part number follows a clear structure: the first digits give the nominal screw diameter, then KA indicates the series. Next comes the number of ball circuits (such as 3P or 1P), the precision class (C3 or C5), and the nominal lead (Z4, Z5, Z10). For instance, W1203KA-3P-C5Z10 identifies a 12 mm diameter screw, KA series, with 3 circuits, C5 precision, and 10 mm lead. This coding lets you identify key specifications at a glance.

These ball screws appear in machining centers, CNC lathes, grinding machines, coordinate measuring machines, laser cutting equipment, and automated handling systems. They also serve the food, pharmaceutical, and automotive sectors, where precise and repeatable linear motion is essential. With proper maintenance, the design supports high feed rates and a long service life.

When selecting a screw, consider axial load, rotation speed, required precision, and environmental conditions. The C3 or C5 class sets the permissible lead error; the number of circuits affects load capacity and rigidity. During assembly, align the screw carefully with the linear guide and supports, and lubricate with grease or oil made for ball screws. Effective sealing keeps contaminants out and extends component life.

NSK KA series ball screws can be interchanged with equivalent products from other brands if the critical dimensions match: diameter, lead, length, nut type, and precision class. Series from manufacturers such as THK, Hiwin, or Bosch Rexroth often have dimensional equivalents, but always verify nut and support compatibility. If you provide a part number from another brand, we will identify the compatible alternative.
