Bently Nevada 31000-00-00-00-059-03-02 31000 Proximity Probe Housing
Product Introduction
The Bently Nevada 31000-00-00-00-059-03-02 belongs to the reliable 31000 series. This housing assembly safeguards proximity probes in harsh industrial settings. For instance, many facilities choose this 31000 housing for turbine bearings, compressors, and gearboxes.
This model 31000-00-00-00-059-03-02 provides a 5.9-inch probe penetration depth. Its 3/4-14 NPT mounting thread fits standard pipe fittings without modification. Additionally, the package includes two plugs and a stainless steel reducer. A cable seal grip with three grommets supports various cable diameters from 1/8 to 3/8 inches.
Since this version uses probe option 00 and cable option 00, the probe and cable are sold separately. Therefore, you can pair it with your preferred 3300 XL 8 mm probe. This flexibility makes the 31000 housing ideal for retrofits or custom system designs.
Technical Specifications
The Bently Nevada 31000-00-00-00-059-03-02 features a glass-reinforced PPS thermoplastic body. This material contains conductive fibers for electrostatic dissipation. Meanwhile, the sleeve and retaining chain use AISI 304 stainless steel. The outer sleeve and exterior screws are made from AISI 303 stainless steel for corrosion resistance.
A Neoprene® O-ring seals the interface between the sleeve and the housing body. Furthermore, the internal seal uses a Viton® O-ring when paired with a 3300 XL probe. The recommended retaining nut torque is 29.4 N·m (260 in·lb) . Proper torque application ensures a dependable seal against moisture and dust.
For protection, this housing achieves CSA Type 4X certification. It also holds IP66 verification and meets CENELEC EN50014 standards. Consequently, it performs well in outdoor, wash-down, and hazardous area installations.
Mechanical and Environmental Ratings
This housing demonstrates outstanding impact resistance. BASEEFA certified it to withstand two 4 Joule impacts at -39°C and at 115°C. Moreover, CSA verified its ability to endure a 7 Joule impact at room temperature. Such durability guarantees reliable operation in demanding conditions.
The temperature range spans from -51°C to +105°C (-60°F to +221°F). Therefore, it supports most industrial applications across various climates. The housing also showed mechanical strength by supporting 912 N in a cantilever test.
Nevertheless, this housing is not designed for pressurized environments. It seals effectively against hose-directed water per NEMA 4X and IP66. However, it cannot resist internal or external pressure. For pressure seal testing, please contact our custom design department.
Installation Guidelines
Follow these steps to install the Bently Nevada 31000-00-00-00-059-03-02 correctly:
Thread preparation : Clean the 3/4-14 NPT fitting hole thoroughly. Then apply a suitable thread sealant to prevent leakage.
Probe insertion : Slide your 3300 XL 8 mm probe through the housing. Next, adjust the penetration depth to achieve your target air gap.
Grommet selection : Choose the correct grommet size for your cable diameter. Options cover 1/8–3/16, 1/4–5/16, and 5/16–3/8 inches.
Cable sealing : Tighten the cable seal grip to secure the cable. Be careful not to over-tighten and damage the grommet.
Nut torque : Apply 29.4 N·m (260 in·lb) to the retaining nut. Use a calibrated torque wrench for accurate results.
After mounting, verify the air gap between the probe tip and target surface. A typical gap ranges from 1.5 mm to 2.5 mm. Finally, perform a full system calibration before starting your machinery.

Frequently Asked Questions
1. Is the 31000-00-00-00-059-03-02 compatible with all 3300 XL probes?
Yes, this Bently Nevada 31000-00-00-00-059-03-02 works with all 3300 XL 8 mm probes. Its internal sealing matches the probe's Viton O-ring perfectly.
2. Why does this housing exclude the probe and cable?
The probe option 00 and cable option 00 mean these are sold separately. Therefore, you can select the exact probe length and cable type for your needs.
3. Can I install this housing in a classified hazardous area?
Yes, the housing meets CENELEC EN50014 for electrostatic dissipation. However, verify that your complete probe assembly also carries the required approvals.
4. What cable diameters does the seal grip accommodate?
The included grommets support cables from 1/8 inch up to 3/8 inch. Specifically, three sizes cover 1/8–3/16, 1/4–5/16, and 5/16–3/8 inches.
5. Is this housing suitable for submerged or pressurized service?
No, this 31000 housing is not rated for submerged or pressurized use. It seals against hose-directed water per IP66 but cannot resist internal or external pressure.
