Understanding Bearing Measuring Instruments
Learn the fundamentals of bearing measuring instruments and their critical role in ensuring bearing performance and longevity.

Bearing measuring instruments are specialized devices used to assess the geometric and functional characteristics of bearings, such as diameter, roundness, surface finish, and runout.These instruments employ technologies like laser scanning, contact probes, or optical sensors to achieve micron-level accuracy, ensuring bearings meet stringent industrial standards like ISO 1940.

At ZYS, our instruments integrate advanced algorithms to detect minute deviations that could lead to bearing failure.They are essential for quality control in manufacturing, helping to prevent costly downtime and enhance product reliability. 

Common types include gauges for static measurements and testers for dynamic analysis under load. By providing precise data, these tools enable engineers to optimize bearing design, installation, and maintenance. With applications ranging from automotive engines to wind turbines, ZYS instruments deliver consistent results even in harsh environments.

How To Choose
Key Factors to Consider When Choosing an Instrument
01Required Accuracy (Tolerance Class)

Bearings are manufactured to specific tolerance classes, such as ABEC (Annular Bearing Engineers Committee) for ball bearings and RBEC for roller bearings. A higher number (e.g., ABEC 7 or 9) indicates a higher precision bearing with tighter tolerances. Your measuring instrument must be at least as accurate as the bearing's specified tolerance class. Using a tool with lower accuracy will not allow you to properly verify the bearing's quality.

02Type of Measurement

Determine exactly what you need to measure. Do you need to check the basic dimensions (ID, OD, width), or do you need to verify complex geometric properties like roundness, cylindricity, or surface finish? The tool must be capable of performing the required measurement.

03Environment and Volume

For a high-volume manufacturing setting, automated, non-contact systems like laser micrometers are more efficient. For low-volume inspection or field maintenance, portable, manual tools like calipers and micrometers are more practical. The environment also matters; a clean, temperature-controlled laboratory is necessary for high-precision measurements, whereas a shop floor requires more robust, durable instruments.

04Cost and Calibration

The cost of bearing measuring instruments can vary widely, from a few dollars for a caliper to hundreds of thousands for an automated inspection system. Always consider the total cost of ownership, which includes not only the purchase price but also the cost and frequency of calibration. Precision instruments require regular, professional calibration to maintain their accuracy.

Maintenance And Calibration Guide
Essential steps to maintain and calibrate your ZYS instruments for sustained accuracy and performance.
  • Daily Cleaning

    Wipe sensors and probes with lint-free cloth and isopropyl alcohol to prevent dust buildup.

  • Monthly Calibration

    Use certified reference standards to adjust instruments, documenting results for ISO audits.

  • Environmental Checks

    Store in controlled conditions (20°C ±2°C, humidity below 60%) to avoid thermal drift.

  • Error Diagnosis

    If readings fluctuate, inspect for worn probes or software glitches; run diagnostic tests via ZYS app.

  • Probe Replacement

    Replace contact probes every 6 months or after 10,000 cycles to maintain ±0.001mm accuracy.

  • Software Updates

    Install firmware updates quarterly to enhance features and fix bugs.

  • Professional Servicing

    Schedule annual servicing with ZYS technicians for comprehensive checks and recalibration.

  • Troubleshooting Issues

    For error codes, consult the manual or contact support; e.g., E101 indicates sensor misalignment.
