What Problem Does It Solve?

Large and extra-large bearings are difficult to move for inspection, surface quality must be assessed immediately after grinding. Measuring curved surfaces such as grooves and raceways is challenging. The Beijing TIME3221 portable roughness tester brings laboratory-level precision to the production line, enabling on-site, real-time surface evaluation.

Main Functions

  • On-site Rapid Inspection: Single-handed operation, outputs full parameters such as Ra and Rz within 10 seconds. TFT touch screen displays roughness curves in real-time.
  • Direct Measurement of Large Workpieces: Direct measurement of large and extralarge bearings without moving them.
  • Strong Curved Surface Measurement Capability: Vertical range ±200μm (full scale 400μm), system resolution 8nm, suitable for bearing grooves and raceways.
  • Multi-parameter Evaluation: Capable of measuring and evaluating Ra, Rp, Rv, Rt, Rz, Rq, and other parameters.
