Product Description

NS25JM is an NSK NS series linear guide (Standard Series, Low-Profile) interchangeable block: size 25, block type JM (Flanged block, short length (Medium-load/Short type)). Basic dynamic load rating C50 17,700 N (50km rated life), C100 14,000 N (100km rated life), basic static load rating C0 20,800 N, assembly height H approx. 33 mm, mounting hole M8×1.25×10 (NSK official catalog CAT.

In the interchangeable series, blocks and rails are purchased separately and freely combined, which simplifies maintenance and replacement, and supports NSK K1-L long-life lubrication units for extended maintenance-free operation.

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 NS25JM?

Nahshon is the NSK distributor in Taiwan. Add NS25JM to your inquiry list along with your stroke, load and operating conditions, and we'll confirm the specification, quote and lead time.
