FAQ

How do I choose between precision grades C3, C5 and C7?

For measurement and machining equipment that need high positioning accuracy, choose the ground-finish C3/C5 grades; for general material handling and automation mechanisms, the rolled-finish C7 grade is sufficient and offers a cost and lead-time advantage.

Can the shaft ends be custom-machined?

Yes. Nahshon offers custom shaft-end machining for NSK ball screws, completing shaft-end turning and heat treatment to your drawings, saving you the in-house machining step.

How do I confirm pricing and lead time for W0801MS-2Y-C3T1.5?

Nahshon is the NSK distributor in Taiwan. Add W0801MS-2Y-C3T1.5 to your inquiry list along with your stroke, load and operating conditions, and we'll confirm the specification, quote and lead time.
