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


  • These are flange type ball rollers with spring plunger function.
  • The attachment height can be easily determined.
  • Install and remove by using BRW Specialty Wrench.
  • 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.

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.
