The Cross Roller Guideway, specifically types like the SCHNEEBERGER R and RNG, are precision linear guides designed for high-load applications requiring minimal friction and high precision. The design typically includes two hardened rails with a cage that holds cylindrical rollers crossed at 90 degrees,
allowing for load support from multiple directions. This setup ensures high rigidity and precision due to the line contact between the rollers and the guideways.The Type R guideways by SCHNEEBERGER are known for pioneering as the first standardized frictionless guideways, effectively handling medium to high requirements On the other hand, the Type RNG represents an advanced version, offering significant improvements such as a threefold increase in load capacity, enhanced rigidity, and precision, alongside reduced contamination risks due to narrower gaps between guide rails.
Cross roller guides, in general, are characterized by their ability to provide high load ratings, stiffness, and precision compared to traditional ball-caged guides. They achieve this through a unique roller arrangement that supports loads from all directions, including high overturning moments. This makes them suitable for applications requiring the utmost precision, such as pick-and-place machines, medical scanning devices, and semiconductor lithography.
These guides are highly valued in various fields, including automation, metrology, optics, and more, due to their high rigidity, compact design, and almost maintenance-free operation. They offer significant advantages, including high load capacity, smooth and quiet operation, and long service life, thanks to their robust design and precise manufacturing.

However, it's worth noting that cross roller guides can be more expensive than other types due to their precision components and the need for exact mounting surfaces. They also have a limited travel length due to their design and require careful assembly to prevent issues like cage creep
