Plain Rod Eye or Spherical Rod End on a Hydraulic Cylinder: Which Should You Use?
Use a plain rod eye when the rod moves in one flat plane, and both pins are parallel and held rigidly. Use a spherical rod end when the rod’s movement leaves that plane, when the structure bends under load, or when the brackets cannot be kept in line. A spherical joint lets the rod tilt, […]
What Types of Rod Ends and Rod Eyes Are Used on Hydraulic Cylinders, and How Do They Differ?
A rod end or rod eye is the metal part that joins the end of a cylinder’s piston rod to the machine. The rod pushes and pulls, and the rod end passes that force on through a pin. Rod ends differ in three independent ways: how they attach to the rod, how they join the […]
How Do You Size a Rod End for a Hydraulic Cylinder for Push and Pull Force, Shock Loads and Safety Factor?
To size a rod end, work out the largest force the cylinder can produce (push and pull separately, at the highest pressure the circuit can reach), classify the load as steady, changing, reversing or shock, choose the safety factor for that class, and pick a rod end whose rated load covers force times factor. No […]
