Product Features

SWP Piano Spring has good resistance to elastic reduction and fatigue resistance;

NBR sealed dust ring protects the movement from cleaning and extends the maintenance cycle

Refined machine movements such as fully CNC machining centers provide excellent and stable protection against rebound values

Soft and wear-resistant rubber sleeve for comfortable operation of the rebound tester

Fine grinding spherical zero adjustment screw, rebound firing smoother

Improved pointer design, easy to adjust friction and stable

The precision is suitable for aluminum alloy flanges that are not easily damaged, and the high-strength hooks are wear-resistant (based on actual reports) and not easy to hang empty

The integrated design of the chassis ensures that the guide keys and supports are not damaged or detached; The button adopts stretching technology, which is not easy to fall off
