CRG High Rigidity Roller Type Linear Guideway with Cover Strip
FEATURE Super high rigidityCRG 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 lifeCompared 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 stripIn 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. APPLICATIONSCNC machining centers, heavy duty cutting machines, CNC

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.
(1) Non-interchangeable type
