T6912 Bearing End Face Protrusion Measuring Instrument Introduction: In modern industry, high-precision shaft systems such as precision machine tool spindles and precision instrument shafts are mostly paired with angular contact ball bearings. These bearings not only require their own high precision, but also strictly control the pairing parameters (contact angle, stiffness, friction torque, etc.) of the two bearings when used in pairs, as well as reasonable axial loads. Otherwise, it will directly affect the rotation accuracy, stiffness, vibration, noise of the spindle, and reduce the life of the bearings. The T69 series bearing end face protrusion measuring instrument is used to measure the protrusion and recess (negative protrusion) of angular contact bearing end faces. It is used to solve various assembly problems of paired bearings and is an essential technical guarantee for bearing manufacturing enterprises to carry out universal assembly. It is also a necessary tool for spindle and machine tool production enterprises to select bearings. characteristic: 1. Measure the bearing protrusion under rated preload, and the value should be reliable and accurate. 2. Manual pneumatic loading, accurate, stable, reliable, and impact free loading. 3. The instrument adopts an air floating spindle, which has the advantages of high rotational accuracy, good stability, strong load-bearing capacity, non-contact, non wear, and long service life, achieving dynamic measurement. 4. High measurement accuracy, good repeatability, and high measurement efficiency. 5. The instrument has high integration and occupies a small area. 6. The instrument's air bearing spindle adopts a new material air bearing, which has high reliability and strong fault tolerance. Even if there is slight friction on the spindle caused by gas interruption misoperation, it does not affect its use. Technical parameters: Measurement range outer diameter: D26~120m Range:- 200μm~μ200 Measurement load: 10~400N Indication error: Soil 1 μ m Repeatability of indication: 1 μ m Measurement selection: maximum value, minimum value, random value, average value
