Characteristics

  • Hexagon head screw type ball rollers for upward applications. They can be installed or removed by using a open-ended spanner or ring spanner.
  • You can select from the following body and main ball combinations:stainless steel, polyacetal, and PEEK.
  • BRUHP-P is intended for applications that require cleanliness, heat resistance, or chemical resistance, such as FPD production equipment and semiconductor devices.
  • BRUHN-N and BRUHP-P have drain holes and are intended for food production lines and other applications that require cleaning.
  • BRUHS has a small coefficient of friction and can move workpiece with less force.

Material/Finish

BRUHP-P
Main Body PEEK/Light Brown
Main Ball PEEK/Light Brown
Sub Ball SUS440C
(Hardness 55HRC or Higher)

Application

FPD production equipment, semiconductor devices, food production lines, and packaging lines

Precautions for Use

  • BRUHS is for upward applications only. If it used for downward or sideward applications, the product may be damaged or the ball may malfunction.
  • BRUHN-N and BRUHP-P can be used in upward, downward, and sideward facing applications.

Starting coefficient of friction measurement

A heavy object of the max withstand load is loaded on 3 ball rollers. The force to move the heavy object was measured with a push gauge, and the starting coefficient of friction μ was calculated.
