Follow this procedure to install the Model RW.

Inspecting Components before Installation

Thoroughly clean the housing and other assembly parts, and make sure there are no burrs.

Installing the Cross Roller Ring onto a Housing or Shaft

As it is easy for the product to tilt during installation, use a plastic mallet to gradually insert the product by tapping around its outside edge. Continue to hammer carefully until you hear the sound of it making direct contact with the reference surface.

  • Note) When inserting the inner ring, hammer the inner ring. When inserting the outer ring, hammer the outer ring.

Tightening Mounting Bolts

  • Installation to devices is done from the raceway wheel on the rotating side.
  • After attaching the Model RW to paired components, align the mounting bolts while rotating the Model RW several times.
  • Install the mounting bolts. When manually turning the bolts, make sure they do not show skewing caused by misalignment of the holes.
  • Bolt tightening should be divided into three or four steps, from temporary tightening to final tightening, moving diagonally between bolts in order. (See gure on right.)
  • Tighten the bolts evenly, using a torque wrench set to the values in the table to the right.
