FAQ

What is the material and finish of these Seeger rings?

Seeger SP rings are typically made from high-grade spring steel (e.g., Ck 75) and are often phosphated and oiled for corrosion protection. This ensures durability and reliable performance in demanding applications.

Is the SP 90 ring interchangeable with a DIN 471 A90 ring?

No, they are not directly interchangeable. The SP 90 (conforming to DIN 9925/9926) has a different geometry and groove requirement compared to the more common DIN 471 circlip. Always verify your application’s groove specifications before installation.

What is the correct way to install and remove an SP 90 retaining ring?

Installation and removal should be done using special retaining ring pliers designed for external rings. Ensure the pliers’ tips fit securely into the ring’s lugs to prevent the ring from deforming or flying off, which can be a safety hazard.
