Make the bolt pattern and bore work together.
Send OD, BCD, thread, usable center opening and stack height. Include axial and bending loads so a torque rating does not hide an integration problem.

Drilling, tapping and fastener preload correlationMEASURE THE FIXED LOAD PATH
The shaft turns. The sensor stays on the frame.
A Reaction Torque Sensor between a motor or gearbox housing and the fixed frame measures the housing torque without rotating the sensor cable.
For steady-state balance, relate housing torque to shaft torque after accounting for losses and other loads. During acceleration, include rotor inertia and any parallel torque paths. Validate fixture resonance, sensor bandwidth and cross-load limits.
Review fixed-housing vs. rotary measurement ↗
Quote the sensor and readout as a system.
Request mV/V, USB, RS485, analog, CANopen or EtherCAT conditioning. Sampling, filtering, scaling and connector pinout need module-level confirmation.
Build a calibrated kit ↗Compare the original drawing before the part number.
FUTEK, Honeywell, Interface, HBM and Burster references begin a compatibility review. Mechanical fit, stiffness and wiring require separate sign-off.
Request a replacement review ↗ENGINEERING QUESTIONS
Resolve the load path before ordering.
Can a static sensor measure a changing motor load?
Yes, when the sensor remains stationary and the varying housing load is within the complete measurement system bandwidth. Review inertia, losses, resonances and other torque paths before relating it to shaft output.
Is a reference model a guaranteed drop-in replacement?
No. Approve the range-specific mechanical drawing, stiffness, cross-load limits, excitation, sensitivity and connector wiring before a replacement is released.
What comes with the requested calibration?
Request five points in both CW and CCW, the sensor/readout pairing, uncertainty and the traceability chain. The quotation confirms the actual report scope; NIST traceability is not a blanket product certification.
REQUEST QUOTE / CAD
Start with your load and mounting envelope.
Send the installation constraints. We will review the sensor configuration, drawing, calibration scope and commercial quotation.
