Seal Replacement Easy seal replacement The RX line has a unique feature. The complete line from 3⁄8” to 6” is featured with a Quick Replacement Design (QRD). This feature will allow you to repair the RX union while the union is still installed on the machine. The Kadant RX union is the only one offering this feature in a ball bearing line. The RX union is designed for long operating life and short maintenance time to guarantee the best operating times for your production line. How does it work? Step 1. Loosen and remove socket head cap screws (2A) and set aside. Remove head (2). Step 2....
