IKO Anti-Creep Cage Crossed Roller Way H CRWG...H

IKOAnti-Creep Cage Crossed Roller Way H is the product with a cage creep proof function using a rack and pinion mechanism originated from Crossed Roller Way, featuring smooth linear motion with super high accuracy.
By total design review of raceway specification with expanding contact length of rollers and increasing number of rollers, the load rating has been greatly increased without changing mounting dimensions and external dimensions of former CRWG.

Product Features

Anti-Creep Cage Crossed Roller Way H is a linear motion rolling guide in which a roller cage is incorporated between two ways with V-shaped raceways.
By adopting of a cage creep proof function using a rack and pinion mechanism, CRWG...H performs smooth linear motion with super high accuracy receiving loads in any direction as well as former CRWG series. Moreover, by total design review of raceway specification with expanding contact length of rollers and increasing number of rollers, the load rating has been greatly increased without changing mounting dimensions and external dimensions of former CRWG.

1. Load capacity and rigidity of equipment are Improved!
By total design review of raceway specification on former type, the load rating has been greatly increased!
Comparison of Dynamic load rating   Comparison of Static load rating
 
2. Cage creep issue has been terminated!
Cage creep issue has been terminated by built-in rack and pinion gear mechanism with original structure!
Freedom in mounting   High-speed and high-tact operation   Saving energy
Reliable for applications such as a vertical axis where Crossed Roller Way may have chances of cage creep.   Stabilized low frictional smooth running operation is always kept without any cage creep issue even in high-speed and high-tact operation.   Any corrective operation for cage creep is not necessary even for a long time operation.
3. Mounting compatibility!
CRWG...H can be replaced easily to former CRW and CRWG series because they are dimensionary interchangeable with adopting original structure that has rack gear between raceways.

4. Ultimate accurate and smooth kinetic friction!
Combination of precisely finised raceway and non-recirculating cages with super high precision cylindrical rollers crossed alternately provides superbly smooth kinetic friction with very high accuracy.
Improved running accuracy   Suitable for step positioning
Extremely high running accuracy can be achieved without run-out by recirculating of rolling element.   Improvement of precision positioning accuracy and superior corresponding feature to step positioning command can be expected because of the linear motion without stick-slip by extremely small frictional resistance.
