Square Magnetic Mount Block for Sensor - 35mm Triaxial Cube (3-Axis Accelerometer)
Convert Any Single-Axis Sensor into a Precision Triaxial Vibration Measurement Point
The BCNT Square Magnetic Mount Block (Model: BCNT-AJ-SMB-01) is a precision CNC-machined 40×40×20 mm mounting cube featuring 1 single centered female threaded hole on every face (1/4"-20 UNC, 1/4"-28 UNF, and M6 metric) and an embedded 25 kg pull N52 Neodymium magnet at the base. It enables vibration analysts to acquire simultaneous 3-axis orthogonal vibration signals (Horizontal, Vertical, and Axial) without investing in expensive dedicated triaxial sensors or drilling permanent machine holes.
Triaxial Sensor Mounting & Dynamic Vibration Simulator
*Tip: Use 1/4"-28 UNF threaded studs to mount BCNT, PCB, or Wilcoxon accelerometers. Always apply a thin film of silicone grease for optimal high-frequency transmission.
1 Why Choose BCNT Square Triaxial Magnetic Mount Blocks?
Standard cylindrical magnetic bases only allow single-axis measurement perpendicular to the machine surface. When condition monitoring standards (such as ISO 10816 / ISO 20816) require full three-directional vibration data (Horizontal Radial, Vertical Radial, and Axial), technicians traditionally face two expensive compromises:
The Traditional Drawbacks:
- Buying expensive dedicated triaxial sensors (₹25,000–₹50,000 each)
- Drilling 3 separate orthogonal tapped holes into machine casings
- Relocating a single magnet 3 times, introducing angle & surface errors
The BCNT SMB-01 Solution:
- Use standard single-axis accelerometers you already own
- 1 single centered hole on every face guarantees true 90° orthogonality
- Mount once on the machine and measure X, Y, and Z instantaneously

3 Installation & Triaxial Alignment Best Practices
Surface Prep
Clean rust, heavy scale, and peeling paint from the test location to ensure direct magnetic flux coupling.
Couplant Film
Apply a thin film of silicone grease or petroleum couplant on the bottom magnet surface to eliminate microscopic air gaps.
Axis Alignment
Orient the cube faces precisely parallel and perpendicular to the shaft centerline (X: Horizontal, Y: Axial, Z: Vertical).
Roll-On Placement
Roll the magnetic block onto the machine from the edge to prevent violent impact shock to delicate piezoelectric crystals.
4 Frequently Asked Questions (FAQ)
Q1: Can I use this block with single-axis accelerometers from other brands like PCB Piezotronics or Wilcoxon?
Yes. The BCNT Square Magnetic Mount Block uses standardized industrial threads (1/4"-28 UNF, 1/4"-20 UNC, or M6 metric), making it 100% compatible with ICP/IEPE accelerometers and vibration sensors from all global manufacturers.
Q2: How does a single centered hole per face maintain true 90-degree orthogonal accuracy?
Each face is precision CNC machined with perpendicularity tolerance under ±0.02 mm. Having a single centered hole on each orthogonal plane ensures that sensors are mounted exactly 90° relative to one another, keeping cross-axis sensitivity below 3%.
Q3: What is the maximum vibration frequency this magnetic block can measure accurately?
When properly coupled with couplant grease on a clean carbon steel surface, the BCNT SMB-01 delivers a flat linear measurement pass-band up to 2,000 Hz (2 kHz) with mounted resonance exceeding 7.5 kHz.
