RV Series Gonio Way
The RV type Gonio Way from Nippon Bearing (NB), consists of a curved roller cage with a precision ground V-groove. Precision rollers are used as rolling elements, and the non-circulating type provides low fluctuation of frictional resistance, resulting in extremely low frictional resistance curvilinear motion.
Low friction resistance micro feed
The precision grinding process and curved roller cage ensure extremely low frictional resistance and almost no difference between starting friction and dynamic friction so that even minute feeds are accurately followed, resulting in high-precision curved motion.
Low noise
The gonio way is a non-circulating type, so there is no noise generation in the circulation section, and the curved roller cage eliminates contact noise between the rolling elements, resulting in quiet operation.
High rigidity and high load capacity
Rollers have a larger contact area than balls, resulting in less elastic deformation. Furthermore, because they are non-circulation type, they have a larger number of effective rolling elements, resulting in high rigidity and high load capacity.
