Basic dynamic load rating C50 193,000 N (50km rated life), C100 153,000 N (100km rated life), basic static load rating C0 264,000 N, assembly height H approx. 70 mm, mounting hole M12×1.75×13 (NSK official catalog CAT.

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 NH55BL?

Nahshon is the NSK distributor in Taiwan. Add NH55BL to your inquiry list along with your stroke, load and operating conditions, and we'll confirm the specification, quote and lead time.
