TeepTrak vs FourJaw: an OEE comparison across 6 criteria

TeepTrak and FourJaw are both non-invasive, plug-and-play machine monitoring platforms that compute OEE without PLC integration. FourJaw is especially strong in CNC and machining environments; TeepTrak spans a broader set of process industries. This TeepTrak vs FourJaw comparison works through 6 concrete criteria, acknowledging the genuine strengths of each platform so you can match the right tool to your plant.

Criterion 1: sensing approach

FourJaw. Clips sensors onto the spindle or power cable and reads the machine’s electrical signal via its MachineLink device, inferring run, idle, and down states. This is a clean approach that performs well on CNC spindles with clear electrical signatures.

TeepTrak. Uses current clamps plus photoelectric sensors that count finished pieces directly at the output, and magnetic sensors for moving parts. TeepTrak selects the best sensor per machine, allowing direct output measurement where current inference is less precise.

Takeaway. FourJaw optimizes for spindle-current simplicity; TeepTrak for multi-sensor precision. Both are non-invasive.

Criterion 2: industry fit

FourJaw. Strongest in CNC and discrete machining shops. Spindle-power monitoring is a natural match for that environment, and FourJaw’s reputation is built there.

TeepTrak. Deployed across machining plus packaging, food and beverage, pharmaceutical, plastics injection, automotive components, and assembly. Broader sensor mix suited to varied process types.

Takeaway. For a pure machine shop, FourJaw’s focus is an asset. For mixed processes, TeepTrak’s breadth covers more of the floor.

Criterion 3: quality measurement

FourJaw. Tracks Availability via uptime and offers a Production Quantity Report (good and scrap quantities), with OEE relying partly on operator-logged downtime reasons.

TeepTrak. Photoelectric output counting plus the QualTrak module provide a more direct route to measuring good versus rejected pieces, reducing reliance on manual entry for the Quality component.

Criterion 4: changeover and micro-stop precision

FourJaw. Captures downtime and uses a downtime Pareto to highlight loss drivers, with operator-logged reasons.

TeepTrak. Measures changeover time to the second and captures micro-stops from three seconds, giving precise before-and-after data for SMED-style changeover reduction and exhaustive micro-stop capture on high-cadence lines.

Takeaway. For high-mix shops where changeovers and micro-stops dominate losses, TeepTrak’s second-level precision is an advantage on this criterion.

Criterion 5: product suite

FourJaw. Focused platform: machine monitoring, OEE, and energy-usage tracking, with an operator tablet. The strength is simplicity and focus.

TeepTrak. Modular suite: PerfTrak (OEE), QualTrak (quality), PaceTrak (manual/assembly tasks), ProcessTrak (process parameters), MoniTrak (KPI display). Reaches manual and quality use cases beyond machine monitoring.

Criterion 6: scale and references

FourJaw. UK-based specialist with a growing base, well-suited to single-site and regional deployments, and praised for ease of use.

TeepTrak. Founded in 2014, 450+ factories across 30 countries, references including Stellantis, Hutchinson, Nutriset, Alstom, and Aptargroup. Strong fit for multinational, multi-site rollouts.

Honest summary

FourJaw is an excellent, easy-to-use platform that excels in CNC and machining shops, especially for single-site operations prioritizing spindle utilisation and energy monitoring. TeepTrak differentiates on multi-sensor measurement (including direct piece counting), industry breadth beyond machining, changeover and micro-stop precision, a broader module suite, and a proven global multi-site footprint. Match the tool to your plant type and where your losses actually live.

Frequently asked questions

Is FourJaw or TeepTrak easier to install?

Both are plug-and-play and non-invasive, clipping onto the power cable with no PLC integration. FourJaw is well known for its simple setup, and TeepTrak installs in roughly one to two hours per machine without stopping production. On installation ease, both are strong; neither requires an IT project for the first line.

Which is better for a CNC machine shop?

FourJaw is purpose-built for CNC and machining, and spindle-power monitoring suits that environment well. TeepTrak also serves machining but extends to many other process types. For a pure CNC shop, FourJaw’s focus is a genuine strength; for a shop that also runs other processes, TeepTrak’s breadth helps.

Which platform measures quality more directly?

TeepTrak’s photoelectric output counting and QualTrak module measure good versus rejected pieces more directly, while FourJaw’s OEE relies partly on operator-logged reasons and a quantity report. If Quality is a major part of your OEE gap, TeepTrak has an advantage on this component.

Does FourJaw measure changeover time precisely?

FourJaw captures downtime with operator-logged reasons and a downtime Pareto. TeepTrak measures changeover time to the second, which provides more precise before-and-after data for changeover reduction programs. For SMED-focused shops, evaluate this difference closely.

Which is better for multiple factories?

TeepTrak’s deployment across 450+ factories in 30 countries makes it well-suited to multi-site, multi-country rollouts with consistent methodology. FourJaw is well-suited to single-site and regional deployments. Your site structure should weigh heavily in this decision.

Can both platforms work on old machines?

Yes. Both read the electrical signal non-invasively and work on any mains-powered machine regardless of age, make, or model, without PLC integration. Legacy equipment is addressable by either platform.

What is the most reliable way to compare them?

Run a head-to-head pilot on a comparable set of machines, ideally including the machine types most important to you. Compare data quality, sensor fit, quality measurement, changeover reporting, and the workflows your team uses. With platforms this close, real data from your floor is the best decision tool.
