21022-30-10-017-03 | Bently Nevada Dual Axial Probe Housing Assembly

Introduction

When rotating machinery requires precise axial thrust position monitoring, the 21022-30-10-017-03 from Bently Nevada delivers a robust solution. This dual axial probe housing assembly is designed for mounting on the end of a machine nearest the thrust bearing. It allows both probes to observe the shaft end for axial thrust position movement. The enclosure mounts using four standard machine screws, making installation straightforward.

Key Features & Technical Specs

• Product Type: Dual Axial Probe Housing Assembly
• Probe Option: 3300 XL 11 mm probe with multiple approvals
• Probe Cable Length: 1.0 meter (39 inches)
• Probe Penetration: 1.7 inches
• Fittings Option: Two cable seal grips with grommets for cable sizes 1/8-in to 3/16-in, 1/4-in to 5/16-in, 5/16-in to 3/8-in; two 3/4-14 to 1/2-14 NPT reducers
• Housing Material: Aluminum alloy (sand cast, 0.3% copper free) with sleeves from 304 stainless steel
• Weight: 3.6 kg (8 lb)

One distinctive feature is the external mounting design. It allows probe adjustments from outside the machine. This reduces downtime during setup and maintenance. The removable cover provides easy access for setting probe gaps.

Applications & Use Cases

Industries rely on the 21022-30-10-017-03 for critical thrust position monitoring. It is ideal for turbines, compressors, and pumps where axial position must be measured accurately. The housing protects probes from dust, splashing liquid, and other environmental factors. This makes it suitable for harsh industrial environments.

Installation & Setup

Mount the enclosure on the machine case using four standard machine screws. The probes install into sleeve/adapter assemblies. These assemblies mount directly onto the machine case through two 3/4-in NPT threaded holes. Fittings are supplied as a kit and are not pre-installed when the housing is shipped. This allows you to configure the cable seal grips and reducers as needed. Always follow the manufacturer's manual for proper gap settings.

Maintenance & Reliability

Regular inspection of the housing and probe connections ensures long-term reliability. The aluminum alloy housing resists corrosion. The 304 stainless steel sleeves add durability. Check the cable seal grips periodically for wear. This helps maintain a protective seal against contaminants. Following a routine maintenance schedule extends service life and reduces unexpected downtime.
