As high-precision measuring instruments, dial indicators can magnify and display minute displacements (at 0.01mm level) through mechanical structures. They are fundamental tools for detecting dimensional deviations and geometric errors in bearing production, widely used in all stages from raw blanks to finished products.

Core Application Scenarios

Blank and Turning Processes
  • Inspect bearing ring blank height and roundness deviations
  • Verify dimensional accuracy of bores and outer diameters after turning
  • Calibrate initial raceway positions
Grinding and Final Inspection
  • Measure raceway roundness and cylindricity
  • Check rolling element diameter consistency
  • Verify bearing ring end face parallelism
Assembly Process
  • Detect radial and axial clearance of bearings
  • Calibrate coaxiality of bearing installations
  • Verify proper fit tightness
Usage Precautions
  • Use light contact – avoid excessive pressure
  • Calibrate to zero before measurement
  • Regularly verify accuracy with standard gauge blocks
  • Use stable stands to reduce vibration effects

Why Choose Dial Indicators?

Dial indicators are easy to operate and provide quick responses, making them ideal for rapid on-site inspection in workshops. With much lower costs than precision equipment like CMMs, they offer an excellent balance of accuracy and efficiency in mass production, particularly suitable for the strict micron-level deviation control required in the bearing industry.
