Frequently asked question (FAQ)
- Question: What role does a ball plunger play?
- Answer: It specifies the stroke of the front ball and can be used for temporary positioning and indexing of workpieces.
- Question: What role does a spring plunger play?
- Answer: With pin-shaped front section, it can be used to eject workpieces or stoppers.
- Question: What is the difference between a ball plunger and a spring plunger?
- Answer: A plunger is headed with a steel ball and its stroke is the displacement of the ball. A spring plunger has a pin-shaped front section and the displacement stroke of the pin is used for such purposes as temporary positioning and indexing of workpieces.
- Question: What is the meaning of load min and max?
- Answer: The min. load represents the initial load, and the max. load represents the load at the maximum press-in limit of ball head.
