Reasons for large runout of precision piston rods:
1. Machining, such as incomplete grinding sequence;
2. The positioning reference is not the same or the form and position errors between the reference are very poor;
3. The fitting tolerance of each fitting component is not selected properly;
4. The support ring is worn, with the first two being before installation and the last two being after installation.
In various mechanical systems with linear reciprocating motion, precision piston rods play a supporting or transmission role, with high accuracy, good wear resistance, and high strength. Suitable for various cylinders, oil cylinders, piston rods, packaging, woodworking, textile, printing and dyeing machinery, die-casting machines, injection molding machines, and other mechanical guide rods, top rods, etc.
