The NSK SA series is a ball screw line that turns rotary input into axial travel, and it does so with high efficiency and repeatable positioning. Machine tools, machining centers, automation cells and positioning axes are the usual homes for these screws. MR Industrial Accessories LLC supplies this line and assists with configuration questions before you commit to a part number.
Reading an SA code is straightforward once you know the blocks. The letter W at the front identifies the screw type, the digits right after it give the nominal diameter, and SA marks the series. Suffixes carry the rest: 2Z or 4Z tells you how many ball circuits are inside, C5 or C6 is the accuracy grade, and Z5 or Z6 is the axial clearance. Take W2802SA-2Z-C5Z5: 28 mm diameter, two circuits, C5 accuracy, Z5 clearance. W2803SA-4Z-C5Z6 pairs four circuits with C6 accuracy and Z6 clearance.
Typical applications include milling machines, CNC lathes, grinding machines, coordinate measuring machines, Cartesian robots and test rigs. You also find SA screws in precision presses, bottling lines and laser or plasma cutting tables. Low friction combined with the ability to carry heavy axial loads suits them to demanding, continuous duty.
Selection comes down to axial load, speed, stroke length and the accuracy your process needs. The Z seal keeps contaminants out; where chips or dust are present, look at adding further sealing. Lubrication, grease or oil, should follow the manufacturer's guidance. Alignment between screw and guides matters, and so do support mounting and proper tightening of the nut, since all of these influence wear and performance.
SA series screws can replace ball screws from other makers when performance is equivalent, though fit depends on mounting dimensions, lead, diameter and nut style. Send whatever you have, another brand's number or just measurements, and we will point you to the matching option. Reach MR Industrial Accessories LLC on WhatsApp or by email with the full part number to get a quote and help narrowing down the configuration for your equipment. If the variant you need is not something you can identify, send the model or dimensions and we will take it from there.

Frequently asked questions
- What do the suffixes on an NSK SA series ball screw tell me?
- They describe the internal and performance details: the digit ahead of Z is the count of ball circuits, C5 or C6 gives the accuracy grade, and Z5 or Z6 gives axial clearance. Those values drive how the screw fits your accuracy and rigidity needs.
- Should I pick 2Z or 4Z?
- Circuit count changes load capacity and rigidity. A 4Z screw carries more load and is stiffer than a 2Z, and it can also run with more friction. Match the choice to your axial load, speed and required accuracy.
- Can you supply outside the United States?
- We serve customers throughout the United States and in several Latin American countries. Send your part number and location by WhatsApp or email and we will follow up.
