Internal Retaining Rings

Internal retaining rings are retaining rings that are installed inside housings and cylindrical bores. The ring inserts into a groove that creates a load-bearing shoulder to retain parts of the assembly securely into place. As they are placed within a groove, internal retaining rings can handle high rotational speeds. Internal retaining rings come in a vast array of types and sizes, making them suitable for a large number of different applications. The basic principle of an internal retaining rings is the same regardless of the size of the ring – it pushes outwards to retain components in place. Internal retaining rings can be as small as a millimetre in diameter, but for larger applications – such as wind turbines, they can be as much as three metres in diameter, showing just how versatile internal retaining rings can be. Used extensively in automotive and aerospace industries, internal retaining rings are cost-effective and highly efficient.
