What are the different tightening methods for a screw?
Written by Hiroki Goto, Engineering Manager NBK America LLC There are several ways of securing parts together, but the screw — a mechanical fastener with a threaded shaft — is still the most common. The primary role of screws (and bolts) is to fasten objects using axial force generated from tightening. Typically, the torque method…
How do flat and lock washers differ?
~ Article courtesy of NBK America LLC Generally, washers are used to distribute a fastener’s load, reducing friction and preventing loosening. A washer is a plate with a hole, which lets a fastener pass through it. The most common shape is a flat disk with a concentric hole. Before a threaded fastener, such as a…

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 […]
