| PROFILE RAIL RUNNER BLOCK DESIGNS |
Precision Actuator Group |
|
 |
Intechangeable with other manufacturers NOOK Precision Profile Rail Systems provide stable and efficient linear motion guidance under variable speeds and high load conditions.
NOOK Precision Profile Rail runner blocks are available in two designs. One runner block design utilizes steel return tubes for ball recirculation and the other utilizes a plastic end cap for ball recirculation. The tube type recirculation system enables the runner block to be used for higher speed applications. The plastic end cap runner block is narrower in width than the return tube style block. Eight different models are available to meet the requirements of height, loads, mounting holes, etc.
