NBK provides couplings that can be used in special environments such as clean room, vacuum, high temperature (80 ° C or higher) are available. ● Low particle The amount of attached particle is ultra low. This is directly available in a cleanroom. This does not bring contaminated matters into a cleanroom. ● Vacuum-supported A material […]
XGT2 high-gain rubber type coupling: productivity and stabilization time
High-gain flexible coupling which surpasses XGT-CXGL-CXGS-C in performance. This is a single-piece construction with the two aluminum hubs molded with high-gain rubber. The optimal damping and rigidity design enables realization of even greater servomotor gain, leading to reduced stabilization time. Technical information⇒Productivity and stabilization time Suppressing speed unevenness control during stepping motor operation is effective.⇒Suppressing […]
NBK’s new XGHW-C flexible couplings
This video showcases NBK’s new XGHW-C flexible coupling. These flexible couplings feature vibration absorption function added to high rigidity couplings. Additionally, this coupling has a structure with both high rigidity and vibration absorption. The individual dynamic vibration absorbtion is separate from the inertial rotor and elastic body in order to achieve vibration absorption. NBK […]

High gain type coupling from NBK: Video
In this video, we see a single-piece construction coupling with the two aluminum hubs molded and vibration-absorbing rubber. The “XG2” designing with damping and high rigidity helps the coupling meet servomotors’ demanding high gain and its precision positioning requirement. NBK www.nbk1560.com
NBK Flexus line
This is a multi-functional part made of various materials with slits and the portion between the slits works as a spring. It is a simple structure made of various materials with slits and its functionality is demonstrated in a flexible coupling( MST and MSX ). This protects arbitrary spring properties against compression, tension, shearing, and […]
Damping servomotor couplings — New ways to use flexible couplings to minimize hunting and boost system stability
August 27, 2017 update: The full-length technical feature on this servo-coupling topic of damping and gain setting is now live. New technological improvements in servomotors have spurred dramatic improvements in response frequencies. The catch is that vibration (and hunting) tend to arise when designers apply high gain settings to servo systems and use advanced couplings […]
MJC-BL jaw-type, flexible coupling from NBK
The MJC-BL is a jaw type flexible coupling. A tight tit enables transmission with zero backlash at low torque. The easy fit allows users to assemble and partition the hub and sleeve smoothly. The coupling’s flexibility allows eccentricity, angular misalignment and twisting vibration to be accepted. It has electrical insulation and a resistance value: Not […]
Basics: What is a clamping screw
Clamping screws are machine elements which use screw thrust for workpiece fixing and positioning. Point contact by the full ball securely fixes the workpiece. Advantages of using Clamping Screws By replacing hex socket head cap screws and hex socket set screws with clamping bolts when clamping (fixing) workpieces, point contact with workpieces can be achieved. […]
Bellows-type flexible couplings: NBK specifications
Bellows-type flexible couplings from NBK allows for eccentricity, angular misalignment, and end-play. The bellows is stainless steel. MBB couplings work extremely well with servomotors and stepper motors, but are inappropriate for pairing with general-purpose motors. MBB couplings are zero-backlash couplings, though slightly less forgiving of misalignment than come other compliant types. Bellows-type flexible couplings: Selection example Note that […]
