What Problems Does It Solve?
The bearing bore diameter is a critical reference for fitting with shafts or spindles. Deviations in bore diameter (too small to be assembled, too large to cause looseness) directly cause:
- Assembly jamming or shaft wear: If the bore is too small, press-fitting becomes difficult; if the bore is too large, inner ring slip may occur, leading to shaft journal wear.
Our factory is equipped with multi-range, high-precision bore diameter measuring instruments perform 100% full inspection with traceable data, completely eliminating challenges such as “incomplete inspection coverage, low accuracy, and slow efficiency.”
Main Functions
This equipment is dedicated to precision dimensional inspection of bearing rings (inner ring bore, outer ring bore).
Covered Parameter Range
Based on bearing bore diameter sizes, our factory is equipped with dedicated bore diameter measuring instruments to ensure full coverage from miniature to large-size bearings.
Conclusion
All outgoing bearings from our factory undergo 100% full inspection with high-precision bore diameter measuring instruments of the corresponding range, ensuring the bore dimensions comply with P0/P6/P5 grade standards and achieve a precise fit with your shaft diameter.
