Smooth Thru-Hole Donut Load Cells

A smooth center bore keeps the shaft path open while the annular sensing body measures axial compression. Start with shaft clearance, then confirm the loading ring and support geometry.

Low-profile donut and doughnut load cells for axial compression.

Choose the smooth through-hole body by actual bore, loading-land geometry and installed height. The D catalogue contains small 24.9 mm bodies through high-force 76.2 mm bodies; compare each dimensional option rather than treating the full family range as one interchangeable sensor.

A 700 Ω bridge and a full-bridge gauge layout are selectable specification directions. The measured span, non-linearity, deflection and temperature behavior belong to the selected model and calibration record.

Section concept showing active inner loading ring, relieved non-loading cover and separate outer support ring
Section concept · use the selected drawing for contact dimensions

LOAD INTRODUCTION / KEEP THE COVER CLEAR

Load the active ring. Support the outer ring.

The relieved cover protects the strain-gauge region. A washer must bear on the designated land without touching the cover or connecting the moving load to the fixed support.

Mounting review targets

Contact surface ≥40 HRC; flatness ≤0.01 mm. Matched washer option targets HRC 48 and ≤0.005 mm flatness. Confirm parallelism, loading-land diameters and installed stack height.

Raised hub steps and recess depth are specified on the selected drawing. Factory electrical pairing does not remove the need to assess force shunts, support flexibility or installed preload.

PROTOTYPE TO OEM / DIRECT QUOTATION

Price the complete measurement chain.

01 / SENSOR

$260–$480 / pc

Indicative mV/V bare-sensor range. MOQ one for prototype review.

02 / LOAD INTERFACE

+$25 / pair

HRC 48 ground parallel load washers, with loading-land geometry matched to the selected sensor.

03 / CONDITIONING

+$145 standard option

Factory paired USB or standard PLC module. Confirm the exact interface and calibration scope.

Illustrative configuration: $340 sensor + $25 washer pair + $145 standard conditioner = $510/set. Multi-channel, EtherCAT and special environmental options are quoted separately.

Volume quote bands: 1–4 prototypes; 5–19 pieces with a target 15% reduction; 20–49 pieces with a target 25% reduction; 50+ annual OEM agreement. Eligible ID/OD modifications target $0 NRE; new elastic-body designs require a separate review. Final pricing and dispatch appear in the formal quotation.

Resolve fit, signal and loading before ordering.

Can I use a metric shaft with an imperial bore?

Check the actual clearance, runout and thermal range. Nominal inch conversion alone does not establish an assembly fit.

Are washers and paired conditioning included?

Choose the +$25 washer pair and +$145 standard conditioner options in your brief. The quote confirms the selected load interface, signal and calibration scope.

What establishes replacement compatibility?

The original part number and revision, dimensions, loading faces, bridge resistance, excitation, pinout and calibration must match the accepted replacement specification.
