Shaft Insertion Amount When Assembling the Coupling and Single-axis Actuator

Here, we explain the shaft insertion amount when assembling the coupling and single-axis actuator in detail.

The Key to Increased Productivity! Understand the Secret of Reduced Stabilization Time in 2 Minutes

Introducing the features of NBK's High-gain Rubber Type Coupling "XG2", made from integrally molded vibration-resistant rubber. This is the abridged 2-minute version.

AOI_SPI

The ‘XG’ high-gain rubber coupling series is ideal for AOI/SPI productivity improvement!

Here is a discussion of how the XG Series can improve AOI/SPI productivity. Here we introduce the optimum couplings for AOI and SPI.

Choosing the most suitable coupling

We also explain the basic points for selection of the "perfect couplings" to meet customer needs. If you have struggled with selecting the perfect coupling from the many available, this is a must-see.

What is the key to speeding up the Servo System？

This page describes couplings that increase servo system speed. If you haven't heard about the progress made with couplings that connect motors and actuators, you may be missing an opportunity to get better performance out of your servo system.

Choosing the most suitable coupling

There are many types of miniature couplings. How do you choose the “perfect coupling” to suit your needs? We explain the fundamental points you need to know.
