Features

  1. Corrosion
    Resistance Made of AISI 440C stainless steel, and suitable in a corrosive environment, in clean room and for food machinery.
  2. Aligning
    Function Reducing the excess strain on bearing, by aligning the flexure of the conveyor rollerʼs shaft or the error of shaft center.

Precautions

  1. Recommended fit to housing bore is H class of tolerance range. Please consult with us in case of special use conditions.
  2. Axial load may impair the aligning function, therefore is not recommended.
  3. Please refer to the chart below for the recommended tightening torque. Adhesive bond is not recommended. It may damage the bearing.
