Quality Inspection

Bearing residual magnetic detector

Bearing residual magnetometer and digital bearing residual magnetism instrument CJZ-3 is a special instrument for bearing residual magnetism inspection. It is a special instrument designated by the bearing institute for residual magnetism detection of finished bearings. It is mainly used for spot inspection of residual magnetism of finished bearings, also can be used for sampling parts of the production line.

Bearing ultrasonic flaw detector

Ultrasonic bearing flaw detector is a method that uses ultrasonic is able to penetrate into the depth of metal material, and when it cross a section enters another section, reflection occurs at the edge of the interface to check the defect of the part. When the ultrasonic beam passes through the probe from the surface of the part to the inside of the metal, a reflected wave occurs when the defect and the bottom of the part are encountered, a pulse waveform is formed on the fluorescent screen. The position and size of the defect can be judged according to these pulse waveforms.

Bearing magnetic particle detector

Bearing special magnetic flaw detector is a special detector for rings like bearings, gear rings. This equipment adopts Markov's mechanism for rotating flaw detection, which has the advantages of rapid flaw detection speed, comprehensive flaw detection, and large volume of flaw detection. It is suitable for large batches of flaw detection of rings and high detection accuracy.

Steel ball vibration tester

The steel ball vibration measuring instrument is a special instrument for measuring the vibration speed of the rolling bearing steel ball, which is composed of a speed sensor, a sensor position adjusting device, a hydrostatic pressure main shaft, a steel ball quick loading and unloading device, a measuring amplifier and an oscilloscope. The two dashboards display the RMS value of the low and high frequency steel balls vibration speed at the same time. The oscilloscope shows the steel ball vibration speed waveform. The low and high frequency vibration speeding values of the steel ball are closely related to the values of the middle and high frequency vibration speeds of the finished bearing.

Bearing roughness measurement

The bearing roughness detector is a high-precision stylus surface roughness measuring instrument. The instrument can be used for the surface of various parts such as plane, bevel, outer cylindrical surface, inner hole surface, deep groove surface, arc surface and spherical surface. And achieve a variety of parameters of surface roughness measurement. The instrument can be conveniently used to measure the roughness of bearing raceways.

Bearing angle measuring instrument

It is used to measure the diameter, roundness and angle of the bearing inner ring raceway.

Metallographic microscope

The metallographic microscope of the bearing mainly analyzes the relationship between the microstructure of the steel and its chemical composition by examining the morphology of the bearing structure. It is possible to determine the microstructure of the various steels through different processing and heat treatment to judge the quality of the bearing steel.

Profile gauge

The bearing profile measuring device is a precision device for measuring the shape of the plain wire and the cross-sectional profile of various bearing components. In the bearing industry, it can measure the shape of all kinds of rolling elements and raceways, such as the amount of protrusion, contact angle, radius of curvature of the surface, and angle of the reference part.

Hardness Gauge

The hardness test is frequently used before and after the use of the bearing, its main purpose is to determine whether the material meets the hardness requirements or analysis the bearing specific reasons through measuring the hardness of the bearing.

Bearing clearance tester

The bearing clearance tester is one of the important quality indicators of the bearing and is an important factor affecting the vibration, noise and life of the bearing.

Roundness detector

The roundness test is mainly used to detect the roundness of the inner and outer ring of the bearing. The roundness of the bearing ring does not reach the standard, which directly affects the bearing rotation accuracy, vibration, and noise. It also affects the clearance, stiffness and friction torque of the bearing, as well as the bearing's fatigue life and working reliability. So roundness control is very important for bearing rings, especially for high-tech bearings such as military, railway, precision, and automotive bearings, the measurement of roundness is even more important.

Bearing vibration tester

The bearing vibration measuring instrument is a special instrument for measuring the vibration of deep groove ball bearings, angular contact ball bearings and tapered roller bearings.
