Custom Precision Machining Toy Shaft with Retaining Ring Groove and Plastic Insert for Pre-installed Circlip Shaft Assembly
This toy shaft with retaining ring groove, also known as a pre-installed circlip shaft, is a precision plastic insert locating shaft designed for toy hardware assembly. It is engineered for embedding into plastic injection molding. The reserved circlip groove allows quick installation of circlips to limit axial movement. The surface is smooth with low friction, ensuring stable and flexible rotation of toy movable parts. We support custom precision machining according to drawings or samples to match various toy structure requirements.
- Pre-machined circlip groove with good matching tolerance for circlip assembly — not easy to fall off.
- Suitable for plastic injection insert molding, fixed firmly inside plastic parts.
- Smooth shaft surface, burr-free, low noise during rotation, safe for children's toys.
- Strict dimensional tolerance, consistent batch quality.
- Available in multiple material options: carbon steel, stainless steel, brass as required.
- Non-standard custom service: diameter, length, groove position and size can be customized by CNC machining.
