+# CDSL Bridge: Bearing Housing
+
+- Use for a bearing seat, bearing support, pillow-block-like body, or bushing seat, not a rolling-bearing assembly.
+- Invariants: one bearing axis, distinct bearing seat and shaft-clearance diameters, a locating shoulder/depth, and a mounting base or flange.
+- Plan: base/support add -> coaxial shaft bore -> larger bearing pocket/counterbore -> mounting holes -> ribs/bosses -> late finishing.
+- Keep bearing outer diameter, seat depth, shaft clearance, center height, wall thickness, and mounting pattern separate.
+- Ribs must connect base and support; never add floating decorative ribs.
