Proto J399 retaining ring plier (also known as circlip plier) is used to place rings on motor shafts, actuators and gear assemblies. It is ideal for the installation and removal of external or internal retaining rings

Working Mechanism:

• This retaining-ring plier is used to install and remove snap rings fitted onto a shaft or into a bore and hold components in place.
• The tip offers a tight grip on the rings to prevent them from flying off.
• Its jaws can be adjusted for accommodating rings within a fixed diameter range.

Features:

• This plier features fixed tips that are induction hardened and precision formed for wear resistance and accurate fit.
• It converts from external to internal or vice versa when the pivot screw is moved to an adjacent tapped hole.
• It is made of carbon steel for structural rigidity and shock resistance.
