Precision Bearing Housing

A high-tolerance bearing housing engineered for repeatable CNC production, holding tight concentricity between mating bores under load.

Precision Bearing Housing

Challenge

Meeting tight GD&T tolerances on bore alignment while keeping the part machinable in a single setup to control cost.

Approach

Modeled the housing in Siemens NX with a single-setup machining strategy in mind, then ran tolerance stacking to confirm the design met fit and finish requirements.
