Product Description

RS1610A is a standard-length rolled shaft for NSK R-series (transfer equipment) ball screws: shaft diameter 16 mm, lead 10 mm, rolled accuracy Ct10 with slight clearance (no preload). Standard lengths: 500 / 1,000 / 1,500 mm (ordering code = RS + dia/lead code + A + length code in 100 mm units: 500 mm -> RS1610A5; 1,000 mm -> RS1610A10; 1,500 mm -> RS1610A15). Shaft ends are supplied blank - cutting, annealing, turning and keyway milling are done by the customer, or can be arranged via NSK / Nahshon (machining guidelines: E3162 B340 / B345).

R-series nut assemblies and screw shafts are sold separately: nuts ship mounted on an arbor and are transferred onto the shaft at assembly (procedure: E3162 B340).

Matching Nuts (2 items on this site)

This shaft matches the following R-series nuts (same dia/lead code 1610; nuts under one code differ only in seals (S) and number of effective circuits, and all share this shaft):

RNFTL 1610A2.5, RNFTL 1610A2.5S

Matching Support Units

Per the official NSK R-series shaft-end tables (E3162 B29-B30, after standard shaft-end machining): fixed side WBK12-01A, WBK12-11; support side WBK12S-01.

Custom Cutting & Complete-Set Inquiry

Quote shaft and nut as a set: add this shaft and the nuts you need to the inquiry list (or just give us diameter x lead). Nahshon can arrange cutting to length and shaft-end machining, and match support units and lock nuts per the official tables - one quotation, one complete delivery.

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 RS1610A?

Nahshon is the NSK distributor in Taiwan. Add RS1610A to your inquiry list along with your stroke, load and operating conditions, and we'll confirm the specification, quote and lead time.
