Features

  1. Made of AISI440C stainless steel, and suitable in corrosive environment, in clean room and for food machinery.
  2. Reducing the excess strain on bearing, by aligning the flexure of the conveyor roller’s shaft or the error of shaft center.
  3. tomeneji-tok2-e2

  4. Available with seals and shields, and suitable in dusty or watery environment.
  5. tomeneji-tok3-e2

  6. Interchangeable to 6200, 6300, 1200 and 1300 series bearings.  The dimensions are the same, except the width of the bearing inside.
  7. tomeneji-tok4-e2

  8. The SH series bearings have more advantages than the standard self-aligning bearings made of SAE52100 steel.

Rollers for chemical film conveyor, clean room application, food machinery, glass substrate conveyor, cleaning system, papermaking machine, printing machine, etc.

Specials

The SH series bearings are available with special lubricants like H1 grade food grease, low-emission grease, fluorine grease or solid lubricant for vacuum condition, and ceramic balls and fluororesin seals can be used upon request.

Precautions

  1. Recommend fit to housing bore is H class of tolerance rang. 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. Glue is not recommended. It may damage the bearing.
