Don't let this gap widen

Why this program matters

Without this upskilling, your team accumulates a technological gap that translates directly into productivity loss.
Organizations that don't train their talents on key topics see their competitiveness drop.
Every quarter without training is a gap widening with competitors who invest.
The cost of inaction quickly exceeds that of well-targeted training.

Learning objectives

Master spectral analysis and envelope demodulation to diagnose bearing defects in advanced professional training.
Select appropriate resolution, windowing, and averaging for the type of defect sought on real machines.
Calculate the characteristic frequencies of a bearing from its exact geometry.
Apply envelope demodulation and accurately interpret the resulting spectrum.
Track defect progression across multiple measurement campaigns.
Estimate time to intervention from spectral data and historical records.

Program

Module 1Signal acquisition and spectral setup (FFT, resolution, windowing)

Participants perform vibration measurements on rotating machines exhibiting imbalance, misalignment, and degraded bearings. They adjust resolution, windowing, and averaging to optimize detection of characteristic frequencies. Each spectrum is compared to a normative reference before disassembly. Practical exercises validate the impact of parameters on defect visibility.

Module 2Calculation of characteristic frequencies (bearing geometry)

Using real bearings, trainees calculate ball pass frequencies, cage frequency, and internal defect frequencies. They compare results to measured spectra and verify correlation with physical condition after disassembly. Company case studies illustrate the importance of precise calculation to avoid misdiagnosis.

Module 3Envelope demodulation and interpretation (analyzer, software)

The training covers envelope demodulation on signals from degraded bearings. Participants apply the technique, interpret the resulting lines, and compare them to actual disassembly. Comparisons with independent measurements strengthen diagnostic reliability. Deliverables include complete interpretation reports.

Module 4Time tracking and intervention timeline estimation

Trainees monitor the progression of a degraded bearing over multiple campaigns. They estimate time to intervention without setting an exact date, using machine history and standards. The thread concludes with final disassembly to validate the complete diagnosis. An operational action plan is prepared for the company.

Evaluation method

Methods, materials and delivery

The Training Envelope Spectrum Bearing - Diagnosing Machine Defects program is delivered onsite or remote (blended-learning, virtual classroom, remote presence). At Learni, an industry-certified training organization, every program is built to maximize skills acquisition regardless of the chosen format.

The trainer alternates between demonstrative, interrogative and active methods (through hands-on labs and/or scenarios). This pedagogical approach guarantees concrete learning that's immediately applicable at work.

Equipment required

For the smooth delivery of the Training Envelope Spectrum Bearing - Diagnosing Machine Defects program, the following equipment is required:

Mac or PC computers, high-speed fiber internet, whiteboard or flipchart, projector or interactive touch screen (for remote sessions)
Training environments installed on workstations or accessible online
Course materials, hands-on exercises and complementary resources
Post-training access to materials and educational resources

For intra-company training on a site outside Learni, the client commits to providing all required teaching materials (computers, internet, etc.) for the smooth delivery of the program in line with the prerequisites in the communicated program.

The Learni story

Founded by engineers and learning experts, Learni's mission is to make high-impact tech training accessible to teams everywhere. We work remotely with organizations across the US and Canada, in your time zone, to help teams upskill fast.

Our method

Training quality, guaranteed at every step

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.

Step 1

Rigorous trainer selection

Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.

Triple validation: technical, pedagogical, sectoral.
Minimum rating 4.8/5 over the last 12 sessions.

Step 2

You meet the trainer beforehand

30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.

Live briefing on goals and team context.
Veto right — we swap the trainer for free if needed.

Step 3

Content tailored to your context

No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.

Hands-on cases drawn from your stack and projects.
Program co-written then validated by your team.

Step 4

Continuous quality follow-up

Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.

NPS, knowledge quizzes and skills self-assessment.
Satisfaction guarantee: fully satisfied or free rework.

A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.

FAQ

Frequently asked questions

Which tools are used in Envelope Spectrum Bearing training?+

Hands-on work runs on FFT, resolution, windowing, bearing geometry, analyzer and software. Those tools come from the Envelope Spectrum Bearing program itself, delivered remotely over 4 days, so participants practise on the stack they will use at work.

What can participants do after Envelope Spectrum Bearing training?+

They can master spectral analysis and envelope demodulation to diagnose bearing defects in advanced professional training, select appropriate resolution, windowing, and averaging for the type of defect sought on real machines and calculate the characteristic frequencies of a bearing from its exact geometry. Those are the stated objectives of the Envelope Spectrum Bearing program at Advanced level, checked by the end-of-session assessment.

What does the Envelope Spectrum Bearing program cover, day by day?+

Day 1: Signal acquisition and spectral setup (FFT, resolution, windowing). Day 2: Calculation of characteristic frequencies (bearing geometry). Day 3: Envelope demodulation and interpretation (analyzer, software). Day 4: Time tracking and intervention timeline estimation. The Envelope Spectrum Bearing program runs over 4 days, delivered remotely.

How is Envelope Spectrum Bearing training assessed?+

Assessment relies on practical diagnosis on real machine with written report, spectrum and envelope interpretation verified against disassembly and justified intervention timeline estimate. Learni issues a completion certificate together with the individual assessment report at the end of the Envelope Spectrum Bearing program, which an L&D team can file as evidence.

How much does Envelope Spectrum Bearing training cost per participant?+

Envelope Spectrum Bearing training is priced on quote. The amount depends on headcount, format and how far the syllabus is tailored to your team. A detailed quote is sent within one business day, and team pricing covers the whole group from the second participant.

How long does Envelope Spectrum Bearing training take?+

4 days, available live online (US time zones) or on-site at your offices. Half-day tracks spread over several weeks are possible so the team stays operational.

Who pays for Envelope Spectrum Bearing training?+

Most US teams pay directly through their company L&D or training budget. Learni invoices in US dollars and accepts bank transfer (ACH/wire) or card, with volume pricing for teams. A purchase order is welcome.

What do participants need to know before Envelope Spectrum Bearing training?+

Confirmed experience in vibration measurements on rotating machinery, mastery of signal processing fundamentals, and practical use of a portable analyzer.

Is a certificate issued after Envelope Spectrum Bearing training?+

Yes. A Learni completion certificate is issued, along with the individual evaluation report. Learni is a certified training provider and prepares for third-party certifications, but does not award them itself.
