Bently Nevada 21022-28-05-035-02 Dual Axial Probe Housing Assembly

Technical Specifications Breakdown

Key parameters for the 21022-28-05-035-02 are listed below for quick reference:

Industry Applications for Cost-Efficient Monitoring

Steam Turbine Thrust Position

In steam turbine generators, axial thrust position shifts can indicate bearing wear or shaft misalignment. The 21022-28-05-035-02 housing allows two 3300 XL 8 mm probes to continuously monitor the shaft end, providing early warning of thrust bearing degradation. Early detection reduces repair costs and extends machine life.

Centrifugal Compressor Protection

Centrifugal compressors in gas processing plants require precise axial position monitoring to prevent rotor-to-stator contact. This housing's external mounting enables quick probe gap adjustments without opening the machine case, saving hours of labor per adjustment.

API 670 Compliance for Refinery Pumps

Refineries often mandate API 670-compliant monitoring for critical pumps. The 21022-28-05-035-02 meets this standard, helping operators avoid non-compliance penalties and ensuring consistent, reliable operation.

Installation & Setup Guidance

Mount the housing on the machine end nearest the thrust bearing using four standard machine screws. The probes are installed in sleeve/adapter assemblies that fit into two 3/4-in NPT threaded holes on the machine case. Fittings are supplied as a kit and are not pre-installed; install them during setup. The removable cover provides access for setting probe gaps, allowing adjustments without disassembling the housing.

Maintenance & Reliability

Inspect the housing periodically for signs of corrosion or physical damage. The aluminum alloy housing (sand cast, 0.3% copper free) and 304 stainless steel sleeves offer good resistance to industrial environments. Clean the cover seal and ensure the enclosure remains dust- and liquid-tight to protect probe leads and extension cables. No disassembly of internal components is required for routine inspection.

Cost-Effective Thrust Position Monitoring with API 670 Compliance

For rotating machinery operators, unplanned thrust bearing failures can lead to costly downtime and repairs. The Bently Nevada 21022-28-05-035-02 dual axial probe housing assembly provides a reliable, externally mounted solution for continuous axial thrust position monitoring, helping you avoid catastrophic failures and reduce maintenance costs.

This assembly meets the American Petroleum Institute's API 670 Standard for axial thrust position transducer housings, ensuring compliance with industry best practices. By enabling probe adjustments from outside the machine, it minimizes labor costs and machine downtime during setup or recalibration.

Selection Guide & Purchasing Advice

When selecting a dual axial probe housing, verify that the probe option, cable length, penetration, and fittings match your machine's requirements. The 21022-28-05-035-02 is configured with 3300 XL 8 mm probes, 0.5 m cable, 3.5 in penetration, and two 3/4-14 NPT fittings. For availability and lifecycle status, contact AutoDCSTech.
