Conveyance, fixing and locating work, torque limiting, and indexing


  • These are press fit type ball rollers with spring plunger function.
  • Because the body section is press fitted, the height can be reduced.
  • Their internal springs receive loads evenly even when the load is unbalanced.
  • These rollers can also be used as a general spring plunger with ball for fixing and locating workpiece. The smooth rotation of the ball reduces friction between the main ball and receiving side.
  • Recommended dimensional allowance of attachment hole is H7.

Precautions for Use

  • These ball rollers are for upward applications only. If it is used for downward and sideward applications, the product may be damaged or the ball may malfunction.
  • The bottom section moves the stroke distance of the main ball. Take care with the depth of the attachment hole.
