Constant Section Retaining Rings / Snap Rings
Constant section retaining rings, also known as snap rings, are manufactured with a uniform width along their circumference, providing three points of contact with the groove. Constant section rings/snap rings excel in applications with tight clearances or limited space, thanks to their lug-free design. Customers frequently choose constant section rings due to their robust cross-section, which enhances their ability to withstand impact loads effectively.
Designed to provide constant contact that is uniform across a range of deflections, the portion of the ring protruding from the groove (also known as the shoulder) securely holds an assembly in place.
Constant section rings also provide opportunities for many different end configurations based on application needs.
Sizes available from:
- Standard: .157 to 10” (4 mm to 150 mm)
- Custom: .157” to 15” (4 mm to 380 mm)
Installation
Constant section rings/snap rings are installed in a horizontal direction into a groove in a housing or on a shaft. They don’t require special tooling for installation and removal, although some constant section rings feature notches on the end of the ring to make installation easier.
Application Examples
Constant section rings/snap rings are commonly used in industrial applications across all industries, where they provide a secure and efficient way to hold components in place.
Some common examples include:
- Actuators
- Engines, transmissions and axels
- Orthopedic implants
- Electronics
- Conveyors
- Pumps
