Abstract: A linear motion bearing assembly is provided including a carriage, a rail, and a bearing assembly. The linear motion bearing assembly includes deflectable structure formed in at least one of the carriage, rail and bearing assembly. The deflectable structure is configured to deflect under a predetermined force to affect load bearing characteristics of the linear motion bearing assembly. Pressure transducer structure is disposed adjacent to and configured for engaging the deflectable structure to apply the predetermined force to affect load bearing characteristics. The deflectable structure may include portions of the rail defining a cavity. The pressure transducer structure is disposed within the cavity. In another embodiment, the carriage includes a sidewall depending therefrom whereby the deflectable structure includes the sidewall. In yet another embodiment, the bearing assembly includes a ball retainer having a load bearing plate aperture. The deflectable structure includes a load bearing plate positioned within the aperture. The pressure transducer structure may include piezoelectric structure.
