NBK’s XUT-cross joint type flexible couplings
This is a cross joint type flexible coupling. Slippage of the bush built in the hubs and the pins of the spacer allows eccentricity and angular misalignment to be accepted. The high accuracy fitting of pin and bush allows the extremely small backlash. The load on the shaft generated by misalignment is small and the burden on the […]
NBK’s XGHW-C flexible couplings
Flexible couplings with vibration absorption function added to high rigidity couplings. A structure with both high rigidity and vibration absorption. The individual dynamic vibration absorber＊1 is separate from the inertial rotor and elastic body in order to achieve vibration absorption. ＊1: The mechanism for suppressing resonant vibration phenomena is achieved by connecting the dynamic vibration absorber […]
Coupling stainless steel screw alteration service
Hex socket set screws provided with set screw type couplings and hex socket head cap screws provided with clamping type couplings can be altered to stainless steel. NBK www.nbk1560.com/en-US/
NBK’s Flexus
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 excellent functionality is demonstrated in a flexible coupling（ MST and MSX ). This enables arbitrary spring properties against compression, tension, shearing, and […]
What is the key to speeding up the Servo System？
There are many ways to improve productivity in a servo system. For example, there is the possibility that you can shorten the production cycle time if you use a high-performance servo motor and an actuator. What is a chance to bring out the servo system performance? However, there are some points users are overlooking. It is […]
NBK Wireless Positioning Unit “EPU-200” Series model change notice
A model change for the Wireless Positioning Unit “EPU-200” series will occur as follows. The backwards compatible model will be the “EPU-220” series (scheduled for release on June 29, 2021). There will be no change in price, shape, dimensions, or performance as a result of this model change. Customers who have been using the “EPU-200” series can […]
NBK’s anti-vibration coupling with high rigidity
Many types of shaft couplings are used with various production equipment, which requires high productivity. High-torsional stiffness couplings such as Disk type (Pic1) and Bellows type (Pic2) are primarily used in applications that require high positioning accuracy. On the other hand, recently, the speed response frequency of servomotors is increasing (Fig1), the vibration by hunting […]
Flexible clamping Oldham type couplings from NBK
This is the MOM-C, Oldham type flexible coupling from NBK. FCD400 is adopted in the spacer and the coupling is suitable for low-speed and high-torque specification. High-performance grease is applied in the gap between hubs and the spacer in order to prevent sticking. Slippage of hubs and a spacer allows large eccentricity and angular misalignment to be accepted. A […]
