Vacuum Cup Fittings Spring Buffer Strut MTA-HD Stainless Steel With Brass
1. Introduction
- Spring plunger for handling of workpieces with differing heights, such as curved metal sheets, etc.;
- Soft placement of the suction cup on sensitive workpieces; good compensation for varying workpiece heights;
- For a wide range of applications; available for all suction cups of the standard range;
2. Application:
- Spring plunger with two damping springs for handling of workpieces with differing heights, such as curved metal sheets,etc.
- Handle pressure sensitive workpieces (such as glass) to ensure flexible contact.
- For use under rough operating conditions;
- It is suitable for occasions with short working period and fast transportation speed.
3. Structure

- Spring plunger consisting of a high strength rod made of galvanized steel, guide sleeve (3) and upper (2) and lower (5) damping springs;
- The vacuum channel at the upper end of the Plunger is provided with an internal thread connection (1);
- Thread for suction cup is always a external thread (6);
- For models with anti-rotation function, the stainless steel rod and bearing sleeve adopt matching planar structure;
- Two lock nuts for attachment (4);
