RTW Internal Circlips (R-Type｜JIS B 2804)

The RTW Internal Retaining Ring is manufactured according to JIS B 2804 and designed for installation in internal grooves of mechanical components. It prevents axial displacement or loosening of bearings, washers, and other internal parts.

Featuring a double-hole design on the inside diameter, it can be easily installed and removed using internal circlip pliers, making it ideal for assemblies with limited internal space.
