Description
The 304 Stainless Steel GB893.1 C-Type External Retaining Ring is a precision-engineered fastener designed to secure components onto a shaft by fitting into a machined groove, preventing axial movement. Manufactured according to the GB893.1 Chinese standard, this external retaining ring provides a reliable locking function in mechanical assemblies. Made from high-quality 304 stainless steel, it offers superior corrosion resistance, durability, and long-term performance in demanding environments. Its standard clamp hole design allows for quick and secure installation and removal using standard retaining ring pliers, greatly saving installation time. It plays a critical role in maintaining component positioning, preventing axial movement, and ensuring system stability.
