Overview
The SKF CMPK 70 Bearing Diagnostic Kit is an integrated, field-deployable solution engineered for predictive maintenance professionals conducting routine condition monitoring of rotating machinery. Designed as a purpose-built tri-instrument ensemble, it combines three complementary measurement modalities—vibration analysis, lubricant condition assessment, and non-contact surface temperature profiling—within a single calibrated, transport-ready package. The kit operates on the principle that early-stage bearing degradation manifests simultaneously across multiple physical domains: mechanical energy dissipation (captured as high-frequency acceleration envelope signals), microstructural changes in lubricant chemistry (reflected in dielectric response and particulate scattering), and localized thermal anomalies (indicative of increased friction or inadequate heat dissipation). By correlating data from these orthogonal sensing channels, the CMPK 70 supports root-cause differentiation between incipient fatigue spalling, lubrication starvation, misalignment-induced edge loading, and contamination-driven wear—enabling technicians to prioritize interventions based on failure mode likelihood rather than symptom severity alone.
Key Features
- Tri-sensor integration: Synchronized use of CMVP 50 vibration pen, TMEH 1 oil condition checker, and CMSS 2000 infrared thermometer within a unified diagnostic workflow.
- Vibration analysis capability: CMVP 50 delivers RMS velocity (0.1–55 mm/s, 10 Hz–1 kHz) for overall machine health screening and high-frequency acceleration envelope (gE, 0.01–45 gE, 10–30 kHz) for early-stage bearing defect detection per ISO 10816-3 and ISO 20816-1 guidelines.
- Lubricant integrity verification: TMEH 1 employs optical-dielectric hybrid sensing to assess oxidation state, water ingress, and particle load in both mineral and synthetic base oils—providing repeatable (<5% RSD), semi-quantitative condition grading (0–100 scale) with intuitive green/red status indication.
- Non-contact thermal mapping: CMSS 2000 offers wide-range surface temperature measurement (−32 °C to +500 °C) with traceable accuracy compliant with ASTM E1933 and IEC 62942-1, supporting hotspot identification in bearing housings, motor windings, and coupling interfaces.
- Field-hardened ergonomics: All instruments feature IP54-rated enclosures, ruggedized casings, and battery-operated autonomy—optimized for industrial environments where portability, rapid deployment, and operator safety are critical.
Sample Compatibility & Compliance
The CMPK 70 is validated for use across standard rolling-element bearing configurations—including deep-groove ball, cylindrical roller, tapered roller, and spherical roller bearings—installed in electric motors, gearboxes, pumps, fans, and compressors operating under typical industrial duty cycles. Its constituent instruments comply with relevant international standards: CMVP 50 conforms to ISO 20816-1 (vibration severity evaluation), TMEH 1 meets CE marking requirements under Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), and CMSS 2000 adheres to IEC 62942-1 (infrared thermography equipment performance criteria). While the kit itself does not constitute a certified measurement system per ISO/IEC 17025, all components are supplied with factory calibration certificates traceable to national metrology institutes (NMI), supporting implementation within GLP-compliant maintenance programs and alignment with ISO 55001 asset management frameworks.
Software & Data Management
The CMPK 70 operates as a standalone hardware suite without embedded software or cloud connectivity. However, its output formats are structured for manual entry into enterprise CMMS platforms (e.g., IBM Maximo, SAP PM, Fiix) or spreadsheet-based trend analysis. Each instrument generates human-readable, time-stamped readings—velocity RMS values, gE envelopes, numeric oil condition scores, and temperature measurements—that can be logged alongside asset ID, measurement location, and environmental conditions. For organizations requiring digital traceability, SKF recommends pairing the kit with the SKF @ptitude™ Observer Mobile application (sold separately), which enables photo-anchored data capture, automated report generation, and audit-ready export in CSV or PDF format—fully compatible with FDA 21 CFR Part 11 electronic record requirements when deployed with appropriate access controls and electronic signature protocols.
Applications
- Routine bearing health screening during scheduled walkdowns in manufacturing plants, power generation facilities, and water treatment infrastructure.
- Troubleshooting unexplained vibration increases or abnormal noise in rotating equipment prior to catastrophic failure.
- Verifying lubricant replacement intervals by correlating oil condition scores with operational hours and temperature history.
- Validating thermal performance after bearing re-lubrication or replacement to confirm proper fit and preload.
- Supporting ISO 18436-2–certified Category I vibration analysts in developing baseline signatures and establishing alarm thresholds for critical assets.
FAQ
Is the CMPK 70 suitable for use in hazardous areas (ATEX/IECEx zones)?
No—the instruments in the CMPK 70 are not intrinsically safe or explosion-proof certified. They are intended for general-purpose industrial use in non-classified locations.
Can the TMEH 1 quantify water content or acid number in oil?
No—it provides a composite condition index based on optical absorption and dielectric permittivity changes; it does not perform elemental or chemical speciation. Laboratory analysis (ASTM D6304, D974) remains required for quantitative contaminant or additive testing.
Does the CMSS 2000 support emissivity adjustment?
Yes—emissivity is manually adjustable from 0.10 to 1.00 in 0.01 increments, enabling accurate temperature measurement across diverse surface finishes including oxidized steel, painted housings, and bare aluminum.
Are calibration certificates included with each instrument?
Yes—each CMVP 50, TMEH 1, and CMSS 2000 unit ships with a factory calibration certificate referencing NIST-traceable standards, valid for 12 months from date of shipment.
Can the CMPK 70 be used on vertical shafts or inaccessible bearing housings?
Yes—its handheld form factor and non-contact infrared capability allow measurements on vertically oriented or recessed components, though optimal vibration acquisition requires stable sensor contact perpendicular to the bearing housing surface.
