Description
The Bently Nevada 167563-10 is a specialized 1/4-28 UNF adhesive mounting kit designed for industrial seismic transducers, specifically compatible with the 200350 and 200355 Trendmaster Pro accelerometers, as well as several Velomitor series sensors. This installation accessory allows engineers to securely mount case-mounted vibration sensors directly onto machinery casings where drilling and tapping a traditional mounting stud hole is structurally unfeasible, prohibited, or restricted due to thin walls or underlying internal components.

Engineering Overview & Integration Notes
Adhesive mounting kits like the 167563-10 serve as an alternative to mechanical stud mounting in condition monitoring loops. However, structural and material preparation dictates the quality of the vibration signal transmission.
Mechanical Integrity and Frequency Limitations
While a threaded stud mount offers the truest mechanical link and the highest frequency transmission (often exceeding 10 kHz), an adhesive pad introduces a thin layer of compliance. The 167563-10 is engineered with a flat profile to minimize this damping effect, making it ideal for standard industrial machinery monitoring up to 1 kHz or 2 kHz, such as balance and misalignment tracking on motor-pump assemblies.
Surface Preparation Guidelines
The operational reliability of the transducer installation depends entirely on the bond strength between the machine housing and the pad:
- Remove Coatings: Remove all paint, rust, scale, and surface scale down to bare metal using a grinding wheel or spot-facing tool. The surface must be flat to within 0.03 mm over the diameter of the pad.
- Chemical Degreasing: Clean the surface and the base of the 167563-10 pad using a zero-residue solvent (such as loctite cleaner or isopropyl alcohol) to remove residual oils.
- Adhesive Selection: Use a high-rigidity structural adhesive, such as a two-part epoxy or cyanoacrylate gel designed specifically for industrial vibration applications. Avoid soft, elastic adhesives or silicone compounds, which act as low-pass filters and corrupt high-frequency vibration data.
Field Note: When screwing the accelerometer onto the 1/4-28 UNF stud of the bonded pad, always use a torque wrench set exactly to the transducer’s specification (typically 2.3 to 4.5 N·m or 20 to 40 in·lb depending on the housing). Do not over-torque, as this can shear the adhesive bond or warp the flat interface, causing erratic bias voltage readings.
Frequently Asked Questions
What is included in the 167563-10 kit?
The kit contains the 1/4-28 UNF threaded metal mounting pads designed for industrial adhesives. Be aware that most structural adhesives ship separately due to shelf-life constraints and transport safety regulations; verify chemical inclusions with your sales representative before ordering.
Can I use the 167563-10 on curved motor frames?
No, the pad base is flat. For curved casing surfaces, you must machine a small flat spot-face using a milling tool or choose an alternative mounting option, such as a dedicated magnetic base configuration (e.g., 167563-12) or a contoured adapter pad.
How does temperature affect the adhesive bond of this kit?
The metal pad handles temperatures matching the accelerometer’s operating range, but the total temperature constraint is determined by your chosen adhesive compound. For steam turbines or high-temperature pumps exceeding +100°C (+212°F), verify that your high-temperature epoxy maintains its structural rigidity to prevent the pad from detaching mid-operation.
