Product Advantages

1. Bearing measurement, high stability, high precision

(1) The SJ5800 series Integrated Precision Roughness and Contour Measuring System offers a large roughness measurement range of 12mm to 24mm, suitable for testing both inner and outer sides of bearings. Optional bearing fixtures and roller analysis facilitate testing.

(2) Resolution up to 0.1nm, with system residual error less than 3nm.

(3) Ultra-high straightness grinding-grade friction guide rails and a special ruby pivot system provide ultra-high sensitivity and measurement accuracy during rotation.

(4) Highly stable drive design ensures no vibration or interference during operation, guaranteeing the precision of system scanning motion.

(5) The precision calibration station can correct and compensate for instrument parameters and probe tip wear, meeting the requirements for high-precision contour measurement.

2. Flexible, intelligent, and simple operation

(1) Integrated contour and roughness measurement without the need to switch modules.

(2) One-click plug-and-play probe design with a high-rigidity plug structure, eliminating the need for screw locking, making it convenient, fast, stable, and reliable.

(3) Hardware and software protection for all motion axes reduce probe and instrument damage caused by operator errors.

(4) Equipped with a servo mechanism to prevent rapid descent when scanning steep slopes.

(5) Intelligent constant measuring force system with adjustable force levels from 0.5-3mN, reducing measurement errors caused by force variations, suitable for measuring various soft and hard workpieces.

(6) Combined adjustment control handle allows rapid stage translation, X and Z axis positioning, probe swing, and speed grading adjustment.

(7) Automatic roughness evaluation according to GB/T, ISO, JIS, and other standards.

(8) Simple and intuitive software interface, enabling easy setup and measurement for anyone.

3. Automated, batch, and rapid measurement

(1) For simple workpieces, only the measurement length needs to be set for one-click measurement;

For complex workpieces, segmented measurements can be performed at any position, and templates can be created for batch contour measurement.

(2) In CNC fixed coordinate system mode, batch contour measurement can be performed quickly and accurately.

(3) Automatic saving of measurement results, with diverse report output options after measurement completion.
