21022-00-00-017-00 | Bently Nevada Dual Axial Probe Housing Assembly

What Is the Bently Nevada 21022-00-00-017-00?

When axial thrust position monitoring demands precision and durability, the 21022-00-00-017-00 from Bently Nevada delivers a robust solution. This dual axial probe housing assembly consists of two proximity probes installed in an externally mounted protective enclosure. It is intended for mounting on the end of a machine nearest the thrust bearing to allow both probes to observe the end of the shaft for axial thrust position movement. The enclosure mounts on the machine case using four standard machine screws. The probes are mounted in sleeve/adapter assemblies, which are installed directly onto the machine case through two 3/4-in NPT threaded holes.

The 1.7-inch probe penetration is a distinctive spec that ensures accurate gap setting for reliable thrust position measurement. This housing assembly protects probes, leads, and extension cables from dust, splashing liquid, or other environmental factors. A removable cover on the enclosure provides easy access for setting probe gaps.

Industry Applications & Use Cases

Engineers in the oil and gas, power generation, and heavy machinery sectors rely on the 21022-00-00-017-00 for critical axial thrust monitoring. For example, in a steam turbine application, this housing assembly helps prevent catastrophic damage by continuously measuring shaft position. Additionally, its compliance with API 670 makes it a trusted choice for refineries and petrochemical plants. Moreover, the external mounting design allows probe adjustments from outside the machine, reducing downtime during maintenance.

Installation & Setup Guide

Installing the Bently Nevada 21022-00-00-017-00 is straightforward. First, mount the enclosure on the machine case using four standard machine screws. Then, insert the sleeve/adapter assemblies into the two 3/4-in NPT threaded holes. After that, install the proximity probes into the sleeves and adjust the gap using the removable cover. Finally, connect the extension cables to your monitoring system. Always follow the manufacturer's manual for precise gap settings.

Maintenance & Reliability Tips

To maximize the service life of the 21022-00-00-017-00, inspect the housing and seals periodically for signs of wear or contamination. Check the probe gaps annually or after any machine overhaul. Since the housing is made from corrosion-resistant aluminum alloy and stainless steel, it withstands harsh industrial environments. Regular inspection helps prevent unplanned downtime and extends the life of your thrust monitoring system.
