General
Wear Bushing or Wear Guide assembly
Wear guide assembly or wear bushing helps reduce wear on master bushings and bowls
during drilling operations, particularly when using a top drive. And
the wear guide material is designed to minimize any wear to the
drill string. The wear guide assembly mounts directly in the pin
drive locations on 27½” or 37½” master bushings. Locking drive pins
are optional. The expendable wear guide rings made of copper are for
pipe sized for 3½"~5" and 5½"~6⅝".
To avoid wear on equipment having a bore with a bowl #3 configuration when drilling, it is recommended to install a wear guide. Fits MPCH, MSPC, MSP & MBH1250. |
