[For Users] Spider Identification Guide

Introducing the method for identifying spiders at the time of your order!

The KTR-made coupling spider comes in two types: the flexible jaw coupling ROTEX (for three-phase motors) and the backlash-free servo coupling ROTEX GS (for servo motors), each differing in shape and size. This document explains the types of couplings, allowable temperatures, hardness, and how to specify your order with illustrations, so please take a look. It is a must-read for customers who want to replace their spider but don't know how to identify the product, want to know the confirmation items when ordering, or wish to replace it with one that has a higher hardness than the current spider! Additionally, feel free to contact us with any questions or inquiries regarding the spider.
