Bently Nevada 21022-28-10-XXX-02 Dual Axial Probe Housing

Product Overview

Bently Nevada 21022-28-10-XXX-02 MOD 17480-122 is a dual axial probe housing assembly designed for thrust position monitoring in rotating machinery.

This assembly supports reliable axial displacement measurement in harsh industrial environments.

The housing protects proximity probes, extension cables, and probe leads against contamination and liquid exposure.

The system installs externally on machinery near the thrust bearing position.

Engineers can adjust probe gaps without opening the machine casing.

The assembly complies with API 670 requirements for axial thrust position transducer housings.
