HIWIN CRG High Rigidity Roller Type Linear Guideway with Cover Strip

HIWIN Linear Guideway CRG Series
Linear Guideway Doctor

FEATURE

Super high rigidity
CRG series uses rollers as the rolling elements. Rollers have more contact area than balls so that the roller guideway features higher load capacity and greater rigidity.

Longer service life
Compared with ball type , the contact stress of roller type is distributed in a straight line area, so the contact stress is significantly reduced. Therefore, CRG series can provide longer service life.

Replace bolt cap with cover strip
In place of the bolt cap, the bolt holes are covered with a cover strip. As a result, the surface of rail is smooth and does not accumulate dirt.

APPLICATIONS

CNC machining centers, heavy duty cutting machines, CNC grinding machines, injection molding machines, electric discharge machines, wire cutting machines, gantry machines

Model Number of CRG Series

CRG series linear guideways are classified into non-interchangeable and interchangeable types. The sizes of these two types are the same as one another. The main difference is that the interchangeable type of blocks and rails can be freely exchanged and they can maintain P-class accuracy. Because of strict dimensional control, the interchangeable type linear guideways are a wise choice for customers when rails do not need to be matched for an axis. The model number of the CRG series identifies the size, type, accuracy class, preload class, etc.
