Bently Nevada 31000-29-05-20-050-00-02 Proximity Probe Housing Assembly

Complete English-series housing identity with a protected 3300 XL 8 mm probe, 0.5 m cable and defined machine-case mounting geometry.

Model Overview

Bently Nevada 31000-29-05-20-050-00-02 is an English-series proximity probe housing assembly for installing a radially mounted probe through a machine case. The housing keeps the probe and extension-cable connection externally accessible, allowing gap adjustment or probe replacement without dismantling the machine.

The six option fields define one specific assembly: 29 selects a 3300 XL 8 mm probe with connector protector; 05 specifies a 0.5 m (20 in) probe cable; 20 sets a 2.0 in (51 mm) standoff adapter; and 050 sets 5.0 in (127 mm) of probe penetration with a published sleeve adjustment range of ±0.5 in (13 mm).

The final fields also matter at installation. 00 means the housing is supplied without conduit fittings, while 02 specifies the 3/4-14 NPT mounting thread required with the selected standoff adapter. The resulting C-plus-D geometry is 7.0 in (178 mm), below the datasheet's 12 in threshold for additional sleeve support.

Ordering Code Definition

Every field in 31000-29-05-20-050-00-02 controls supplied hardware or installed geometry, so the suffix must remain intact from enquiry through receiving inspection.

Keep all six option fields

Record 29-05-20-050-00-02 as one suffix. Shortening the identity to 31000 loses the probe type, cable length, standoff, penetration, fitting package and mounting thread needed to reproduce the assembly.

Read C and D together

Option 20 contributes 2.0 in of standoff and option 050 contributes 5.0 in of penetration. Their 7.0 in total is the geometry used for sleeve-support and cable-length checks, not either value in isolation.

Separate fittings from thread

Option 00 omits conduit fittings, but option 02 still provides the 3/4-14 NPT machine mounting thread. Confirm the field conduit plan instead of reading 'without fittings' as 'without a mounting interface.'

Installation and Service Access

The housing protects the measurement path and moves routine probe access outside the machine, but accuracy still depends on mounting, gap and cable documentation.

Mount through the machine case

Verify the 3/4-14 NPT port, standoff clearance and probe target before threading the assembly into place. For radial vibration service, confirm that the machine casing is affixed to the bearing so the relative vibration signal remains meaningful.

Set and document probe gap

Use the approved 3300 XL procedure to establish the electrical gap, then record the final voltage, sleeve position and retaining-nut condition. The ±0.5 in penetration adjustment is for controlled setup, not an undocumented installation allowance.

Keep the service route external

Protect the ClickLoc connection, route the cable without exceeding bend limits and document any flexible conduit with integral 3/4-14 NPT fittings. External access should permit future gap correction or probe replacement without opening the machine case.
