Product Description
CHTR Precision Launches New 6-Meter Single-Piece Rails
- CHTR hiwin hgr25 is Smoothness,Low Noise
The returning device of TRHG hiwin hgr25 linear bearings and rails adopt a simple and lubricant ball recirculation design with shock resistant circulative accessory --strengthening synthetic resin,the smoothness of the movement is good which achievesa smooth and noiseless linear motion - CHTR hiwin hgr25 is Compact Structur
The section and rigidity of TRHG hiwin hgr25 linear bearings and rails attain the most optimal design which is with a small section but high rigidity,thus achieve the purpose of miniaturization of machine tool.
CHTR linear bearings and rails have Five accuracy grades for choose
The accuracy of each type is separated into :Normal, High, Precision,Senior Precisjon,Top Precisjon.
The following are the precision grades recommended for the application.
