Features

  • ・Drastically improved wear life

    Tsubaki developed a seamless solid bush using our unique processing expertise for the previous G7-EX Series.

    The high-precision solid bush with special lube grooves increase the retention of lubricant and doubles the wear life.

    Tsubaki current G8 series has a rust preventative pre-lube that minimizes tackiness, and has 1.2 times longer wear life than G7.
