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 linesPrecautions 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.
| Part Number | Starting Coefficient of Friction μ |
|---|---|
| BRUHS-S（Main Body and Main Ball：Stainless Steel） | 0.03 |
| BRUHS-N（Main Body：Stainless Steel/ Main Ball：Polyacetal） | 0.04 |
| BRUHN-N（Main Body and Main Ball：Polyacetal） | 0.08 |
| BRUHP-P（Main Body and Main Ball：PEEK） | 0.08 |
