LINEAR SHAFT
SHAFT
NB SLIDE SHAFT is a round shaft used in combination with a slide bush. We provide high quality products with our advanced machining and hardening technologies.
Features
We have developed the advanced machining and hardening technologies cultivated through the machining of slide shafts as the inner ring of bushings into rotary motion, and are capable of machining all types of shafts, from roll shafts to shafts for general machinery.
Advanced processing technology
Our long-accumulated machining technologies enable us to perform a wide range of high-precision machining, from simple machining such as step, screw, and tap processing to those requiring advanced machining technologies such as high-speed rotary axes. We can also handle long grinding and drilling.
Excellent abrasion resistance
NB's superior heat treatment technology has realized a uniform and even hardened layer in both the circumferential and axial directions. (See photo).
Special Specifications
Various types of machined shafts according to customer drawings, from SCM and SKS materials to heat treatment and special surface treatment according to customer requests.
Wide Variety of Variations
SN type, SNS type, SNT type, Tapped shaft on bus bar (SNB, SNSB type)
Surface roughness
Surface roughness of 0.4 Ra or less is achieved by precision grinding.
FIT Series
By adjusting the radial clearance between the NB slide bushing and slide shaft through precision grinding, the NB slide bushing and slide shaft can achieve smooth linear motion with minimal rattling.
Type
SN／SNS／SNT（NB SHAFT）
SNB／SNSB（Tapped shaft on bus bar）
