Product Description

RS3610A is a standard-length rolled shaft for NSK R-series (transfer equipment) ball screws: shaft diameter 36 mm, lead 10 mm, rolled accuracy Ct10 with slight clearance (no preload). Standard lengths: 1,000 / 2,000 / 3,000 mm (ordering code = RS + dia/lead code + A + length code in 100 mm units: 1,000 mm -> RS3610A10; 2,000 mm -> RS3610A20; 3,000 mm -> RS3610A30). 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 (10 items on this site)

This shaft matches the following R-series nuts (same dia/lead code 3610; nuts under one code differ only in seals (S) and number of effective circuits, and all share this shaft):

RNCT 3610A5, RNCT 3610A5S, RNFBL 3610A2.5S, RNFBL 3610A5S, RNFTL 3610A2.5, RNFTL 3610A2.5S, RNFTL 3610A5, RNFTL 3610A5S, RNSTL 3610A2.5S, RNSTL 3610A5S

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 RS3610A?

Nahshon is the NSK distributor in Taiwan. Add RS3610A to your inquiry list along with your stroke, load and operating conditions, and we'll confirm the specification, quote and lead time.
