Key Points
- A wired online system suits fixed critical machines watched by in-house analysts.
- Wireless sensors or a service model cover more assets with less setup.
- Ask each vendor the same questions on sensing, connectivity, diagnosis, work orders and pricing, so answers line up side by side.
Teams searching for SKF alternatives usually want continuous monitoring without the integration work of an online system or the labor of vibration routes. Tractian, Augury and AssetWatch each take a different route to that goal. Learn more about wireless condition monitoring sensors and vibration analysis.
Why Do Teams Look at SKF Alternatives?
Teams look at alternatives when SKF's model does not match how they want to monitor machines. SKF's offer spans portable, wireless and online systems. Its online IMx-8/16 unit has 8-16 analogue and 2-4 digital inputs, and its @ptitude Observer software runs on premises or on SKF's cloud hosted on Amazon Web Services.
A broad portfolio gives choice and also means more decisions: which hardware, which software, which distributor. Engineers on r/IndustrialMaintenance ask for alternatives to SKF Decision Support, which is a common starting point for this search.

Tractian
Best for: Plants that want sensor-first monitoring on pumps, motors, fans, gearboxes and compressors, with their own technicians seeing diagnosed faults in one platform.
Overview
Tractian Smart Trac Ultra is a wireless sensor for rotating assets. It samples vibration, ultrasound, temperature and RPM.
Readings go to the Tractian condition monitoring platform, where Auto Diagnosis links signal patterns to bearing wear, misalignment, unbalance and other failure modes. The ultrasound channel tracks friction and lubrication on bearings, which supports condition-based maintenance without a route.
- Setup without cabling: unlike an IMx channel, a sensor needs no wiring; it mounts with adhesive or drill-and-tap and reports within minutes, with CMRP and CAT-certified experts supporting install and training.
- Classified and washdown areas: IP69K rated and hazardous-location certified for ATEX, IECEx, and NFPA 70 Class 1, 2, and 3 (Division I).
- Maintenance systems: diagnosed faults move into CMMS, ERP and EAM tools, Maximo and Oracle included, through Tractian integrations.
Key features
- Vibration trend and spectrum sampling to 64 kHz.
- A battery that lasts 3 to 5 years depending on configuration and environment.
- A 4G/LTE link reaching 3,300 ft in open line of sight and 330 ft around obstacles, with no plant Wi-Fi.
- Severity-ranked failure detection alerts with a root cause and next steps.
Customer results and industries
- Food and beverage: A Unilever food plant in Latin America moved from scheduled inspections and manual vibration analysis to 320 sensors on 40 critical assets. In 112 days, the team prevented 19 failures, avoided 117 hours of unplanned downtime and protected over $796K in corrective costs.
- Chemical: At ICL, a food-grade phosphate supplier, recurring lubrication alerts on a mill exposed gaps in the maintenance plan. After revising it, the team removed one of two annual shutdowns and recovers 400+ tons of output per year.

Tractian pricing compared with an SKF distributor quote
SKF pricing comes from a distributor, tier by tier, while a Tractian quote is scoped to the assets you want covered. Tractian reviews which machines are critical, how they fail and the sensor coverage that catches those failures early, and a specialist prices the plan around that risk.
Questions to ask before you buy
- Can you show a diagnosed fault on a plant like mine, start to finish? Auto Diagnosis ties the signal to a named failure mode, and the alert tells technicians the root cause and next step.
- What does ultrasound add to the vibration data I collect today? It gives an early read on bearing friction and lubrication condition from the same sensor.
- How fast can we get live without new cabling? Wireless sensors with multi-year batteries skip channel wiring, and certified experts support installation and training.
- Do the sensors suit classified or washdown areas? Check the IP69K rating and hazardous-location certification above against your zones.
- Which reference customer in my industry can I call? Ask for the food and beverage and chemical examples above.
SKF
Best for: Companies with permanent, wired measurement points on critical machines and in-house analysts.
Overview
SKF's IMx-8/16 and IMx-8/16Plus Multilog online systems offer simultaneous measurement across channels, 4 GB internal memory, data buffering when communication is down, and Modbus TCP/IP and Modbus RTU support.
Key features
- Online system with 8-16 analogue and 2-4 digital inputs, read from installed sensors, so sensors, cabling and channel counts are planned per machine.
- @ptitude Observer software for analysis, on premises or on SKF's cloud, with automated machine learning, rule-based AI or manual alarm and event log analysis.
- Results shared with historians and maintenance management systems.
- A portfolio that also includes portable and wireless condition monitoring.
- Applications in wind energy, marine, machine tool and process industries.
Pricing
SKF does not publish prices, and its products are bought through distributors, so cost comes from a distributor quote by hardware and software tier.
Questions to ask before you buy
- Which hardware and software tiers does my asset list need, and what does each cost? Ask the distributor for a written quote by tier.
- Do I host software on premises or on SKF's cloud, and who maintains it? With the cloud hosted on Amazon Web Services, each choice moves upkeep to a different team.
- Who installs and configures the system, and who reviews the diagnoses? Observer lets you choose machine learning, rule-based AI or manual analysis, so confirm what support is included.
Augury
Best for: Companies that want AI agents across production operations.
Overview
Augury offers industrial AI agents. Its Machine Health product centers on predictive alerts that state what is failing, how urgent it is and what to do.
Key features
- Machine Health for 200+ asset types in four levels of criticality.
- Recommended actions, reviewed by a vibration analyst alongside AI diagnostics.
- IoT hardware included in subscriptions.
- CMMS and EAM integrations, with alerts passed to a connected system rather than described as native work orders.
- Endpoint 3XS rated IP67, operating from -40 to +85 °C, with a mobile app limited to sensor installation.
Pricing
Augury quotes per customer, with sensors folded into the subscription.
What to confirm with Augury
Sensor types and connectivity are not published, so ask Augury for the current datasheet for your assets. Because alerts go to a connected CMMS or EAM, a gap in that link leaves a diagnosed fault without a task; the criteria for how to choose an AI condition monitoring provider cover this handoff. Request a multi-year quote that spells out sensors, software and services.
AssetWatch
Best for: Companies that want an outsourced reliability team with the monitoring platform.
Overview
AssetWatch provides condition monitoring as a service across vibration, temperature, electrical and oil analysis, and its staff check findings before your team sees them.
Key features
- Continuous and route-based vibration, electrical monitoring and oil analysis in one platform.
- Alerts that cover what was detected, why it matters and what to do next.
- An install of about 1 day, with the first actionable alert after a median of about 3 days.
- A Condition Monitoring Engineer, Asset Reliability Technician and Customer Success Manager on each account.
Sensor frequency range, battery life and ratings are not published.
Pricing
AssetWatch charges a subscription with no CapEx and offers a $199 trial; the full price list is not public, which makes multi-site cost hard to compare with an SKF purchase.
What to confirm with AssetWatch
Ownership and return terms for sensors and data are not stated, so get them in the contract. Ask how price scales with asset count and site size. Since analysts sit between detection and your team, request response times and analyst coverage in writing.
How Do You Choose Between SKF Alternatives?
Start with the decision that changes the most: who collects and interprets data.
- Wired online systems: suit fixed critical machines with in-house analysts.
- Wireless sensors with AI: suit plants that want fast coverage across many assets.
- A service model: suits teams short on reliability staff. Tractian also provides human review of findings when a team wants it, without moving to a full service contract.

Frequently Asked Questions
Who are SKF's main alternatives for condition monitoring?
Tractian, Augury and AssetWatch are three alternatives to SKF's portable, wireless and online condition monitoring portfolio, compared above.
Does SKF condition monitoring cover more than bearings?
SKF's condition monitoring offer covers portable, wireless and online solutions, and the IMx-8/16 lists wind energy, marine, machine tool and process applications.
What is the main difference between wired online and wireless monitoring?
A wired online system such as SKF IMx-8/16 reads analogue and digital inputs from installed sensors. Wireless systems such as Tractian use battery-powered sensors that send data over 4G/LTE, which skips plant network setup.
How do I compare vendors fairly?
Request matching details from each one: what it senses, how data travels, who diagnoses faults, how alerts are prioritized, what the contract covers and how pricing is quoted.
Does Tractian replace an SKF route-based program?
It can replace the routine data collection for assets you fit with sensors. Tractian sensors install wirelessly with expert support, and alerts flow into your CMMS, ERP or EAM through integrations. Assets without sensors still need routes or another method, so most teams map criticality first.
