Axial assembly of retaining ring

The axially assembled retaining ring is installed in the machined groove of the casing/hole (internal) or shaft (external). These rings are manufactured with lug holes - small holes on the lugs for axial internal and external fixing rings - for installation/disassembly using pliers designed for this purpose.
Inverted buckle
Inverted fixed ring is a variant of axial assembly ring, in which the lug hole is inverted to be installed at the bottom of the groove. Inverted lugs allow for greater clearance in the shaft or casing and form a higher uniform shoulder, which is beneficial for securing bearings and other components with large fillet radii or chamfers.
Beveled fixing ring
The inclined fixed ring has 15 ° inclined or angled edges. This angle allows the ring to wedge itself between the groove and the retained part until it cannot go any further, effectively locking everything in place. Think about putting a cork in the bottle. The cork is pressed into the opening until it wedges as deep as possible. The same thing happens when installing the inclined fixed ring into the application. The ring wedges itself into the position between the groove wall and the retained part, causing the so-called rigid end gap to tighten.
Bow shaped fixing ring
The bow shaped retaining ring is a curved version of the standard flat inner and outer retaining rings, which apply preload to the component when installed in the groove. This occupies the end gap and acts like a spring, keeping the component in a compressed state.
In the manufacturing industry, parts cannot be produced to precise dimensions; Therefore, if they are manufactured on the low side of the tolerance, they may become loose or have gaps on the shaft when installing the standard ring. If they are manufactured on the higher side of the tolerance, they will further extend into the groove and prevent the standard ring from being completely installed. Compensating for accumulated tolerance is the design purpose of the bow shaped fixing ring, which acts as a spring once installed in the groove.
