Profile Rail Runner Blocks Part Number Designations |
Intechangeable with other manufacturers NOOK Precision
Profile Rail Linear Guide Systems provide stable and efficient linear motion
guidance under variable speeds and high load conditions.
NOOK Precision Profile Rails are available
in two designs. One 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 carriage
to be used for higher speed applications. The plastic end cap runner
block is narrower in width than the return tube style block. Depending
upon the requirements of height, loads, mounting holes, etc. the
users may choose from eight different models.
