Product Description

SHAFT 


The NB shaft can be used in a wide range of applications as a mechanical component from straight shaft to spindle shaft.  


제품 상세 설명

NB's expertise in machining and heat-treatment turns into manufacturing spindle shaft, roll shaft, and general machinery shaft for rotational motion.
NB's high accuracy technology answers various shaft machining requirements.

Advanced Machining Technology
NB performs a wide variety of highly accurate machining processes to provide custom shafting from relatively simple machining,
such as tapping and shaft stepping, to the more demanding highspeed rotating shafts and spindles.
NB can also answer the special grinding and bore machining requirements.

Special Requirements
Based on the customer drawings and specifications NB will answer the customer requirements in material (SCM, SKS etc.), heat-treatment, surface treatment, etc.

Excellent Wear Resistance
Most commonly used materials are high-carbon chromium bearing steel (SUJ2) and martensite stainless steel (SUS440C or equivalent).
NB's advanced heat-treatment technology gives these materials an excellent wear resistance by quenching and tempering
to achieve a uniform hardened layer in the circumferential and axial directions.
The cross-sectional picture below shows the hardened layer-depth of the NB shaft.

Shaft Supporter and Shaft Support Rail
These components ease the shaft installation and help save the design/assembling time. 

Surface Roughness
Precision grinding results in a surface roughness of less than Ra0.4

FIT Series
This series is a set of NB slide bush and NB shaft. By precise shaft-grinding, FIT series achieves the best-fit clearance adjustment for a smooth, high accuracy linear motion.

Wide Selection of Shaft Types
SN type, SNS type, SNT type, SNB, SNSB type (Center-lined tapped shaft) SNW, SNWS type (Inch shaft) SNW-PD,
SNWS-PD type (Inch, pre-drilled shaft) Spindle shaft, roll shaft Hardened Layer (cross section)

SNB/SNSB type (NB Center-lined Tapped Shaft)
SNW-PD/SNWS-PD type (Inch Shaft, Pre-drilled Shaft)

(주)디와이티 Shaft  3

Center-lined tapped shafts are standardized series for easy selection that can be used with the SA shaft support rails.

The SNW and SNWS types are inch dimensional shafts with the same specifications as SN/SNS type.
SNW-PD and SNWS-PD types are standardized series that can be used with the WA shaft support rails.
