This instrument is a mechanical measuring instrument of comparative method. It is mainly used for measuring the thickness fluctuation of bearing inner ring. There is a special positioning bolt on the platform of the instrument, which can be adjusted according to the size of the bearing to be measured. There is a circular positioning plate on the bolt, which can be adjusted according to different conditions to ensure that the measured height is consistent with the probe height of the measuring instrument, so as to measure the thickness change of the bearing ring.

Customer attention, when choosing the instrument, pay attention to the measuring size range that the product can meet, and pay attention to whether the measuring position of the instrument meets your needs, please refer to the parameters in the table to determine whether it meets your measuring needs
If you have any questions about the size and measurement position of the instrument measurement, please feel free to contact us, we have a professional team to provide you with quality solutions to meet your needs as much as possible
---------------------------------------------------------------------------------------------------------------------------------
- When the instrument is used, it is necessary to adjust the instrument pointer to zero by conforming to the standard size of the target product. There are coarse positioning bolts and fine tuning bolts on the instrument to debug the instrument pointer to the zero position.
- After zeroing the instrument pointer, take down the standard size product, put it into the measurement product, and observe the pointer deviation of the instrument.
- Because the instrument is a comparative measuring instrument, the reading displayed by the instrument is the error difference between the measurement product and the standard size product, and the user needs to determine whether the accuracy of the measurement product is within the allowable range according to the set error range.
- Some instruments have probe equipment and spring equipment, which need the user to pay attention to protection, and avoid the interference of debris on the probe when using, resulting in inaccurate measurement.
- Please pay attention to the anti-rust treatment of the measuring part of the instrument. Due to the different accuracy requirements, if there are rust traces in the measuring position, the measurement accuracy of the product may be affected.
- The instrument is made of all metal, and the weight is heavy, partly in order to maintain the stability of the measurement product and avoid the impact of shaking, partly in order to meet the rigidity requirements required for the measurement of metal bearings. Users should pay attention to safety when using to avoid collision injuries caused by metal parts.
The indicator and the measuring instrument are not integrated, but separate, and in order to ensure the accuracy of the measurement, the indicator needs to be properly kept
In addition, the purchase does not include the indicator, the indicator is sold separately, the specific price please consult
The warranty period of all measuring instruments is one year, and you can contact us at any time if you have any quality problems
