21022-29-10-017-03 | Bently Nevada Dual Axial Probe Housing Assembly

What Makes the 21022-29-10-017-03 Essential for Axial Thrust Monitoring?

When machine reliability hinges on precise axial thrust position measurement, the 21022-29-10-017-03 from Bently Nevada offers a robust solution. This dual axial probe housing assembly is designed for end-of-shaft monitoring, helping prevent costly thrust bearing failures. By housing two proximity probes in a protective enclosure, it delivers consistent performance in demanding industrial environments.

Key Features & Technical Specs of the 21022-29-10-017-03

• Probe Option: 3300 XL 11 mm probe with connector (option 29).
• Probe Cable Length: 1.0 meter (39 inches) as standard.
• Probe Penetration: 1.7 inches (option 017).
• Fittings Kit: Includes two cable seal grips for cable sizes 1/8-in to 3/16-in, 1/4-in to 5/16-in, 5/16-in to 3/8-in, plus two 3/4-14 to 1/2-14 NPT reducers.
• Housing Material: Aluminum alloy (sand cast, 0.3% copper free) with 304 stainless steel sleeves.
• Weight: 3.6 kg (8 lb).
• Standards: Meets API 670 Standard for axial thrust position transducer housings.

A standout feature is the external mounting design, which allows probe adjustments without opening the machine. This reduces downtime during setup and maintenance.

Real-World Applications for the 21022-29-10-017-03

This housing assembly is ideal for turbines, compressors, and other rotating machinery where axial thrust position must be monitored continuously. In petrochemical plants, for example, the API 670 compliance ensures compatibility with industry safety standards. Furthermore, the rugged aluminum alloy housing protects probes from dust and splashing liquids, making it suitable for harsh environments.

Installation Guide for the 21022-29-10-017-03

Mount the enclosure on the machine case using four standard machine screws. The probes install into sleeve/adapter assemblies through two 3/4-in NPT threaded holes. After mounting, set the probe gaps through the removable cover. Note that the fittings kit is supplied separately and is not pre-installed, so plan for on-site assembly.

Maintenance & Reliability Tips

Inspect the cable seal grips periodically to ensure a tight seal against contaminants. Check the probe penetration depth (1.7 in) during routine maintenance to confirm correct positioning. The 304 stainless steel sleeves resist corrosion, extending service life. Regular inspection per manufacturer guidelines helps maintain API 670 compliance.

Compatibility & Integration

The 21022-29-10-017-03 works with Bently Nevada 3300 XL 11 mm proximity probes and extension cables. It integrates into existing monitoring systems that accept standard proximity probe inputs. For system-specific compatibility, consult the official documentation or contact Petro Auto Tech.
