+## API Definition
+
+```python
+def make_roller_chain_sprocket_rsolid(n_teeth: int, chain_pitch: float, roller_diameter: float, sprocket_thickness: float, *, bore_radius: float = 0.0, roller_clearance: float = 0.15) -> Solid
+```

+*Source: std/chain.py*
+
+## Import Surface
+
+- standard library: `import simplecadapi as scad` then `scad.std.chain.make_roller_chain_sprocket_rsolid(...)`; direct submodule import: `from simplecadapi.std.chain import make_roller_chain_sprocket_rsolid`
+
+## Description
+
+Create a roller-chain sprocket from tooth count, chain pitch, roller diameter, and tooth-plate thickness. The pitch radius follows the regular pitch polygon. Circular roller seats are cut at every pitch point and opened through the engineering outside-diameter envelope.
+
+The result preserves assembly-level engagement dimensions. Manufacturing release still requires the selected chain standard's permitted tooth-form range, tooth width, hub, material, heat treatment, runout, and supplier checks.
