Slewing ring without teeth RW series

crossed rollerdouble-rowangular-contact

Achieves high rigidity and precision by increasing the number of rollers with a double-row structure. High rigidity and regulated wobbling accuracy make it optimal for rotating mechanisms in machines with multiple functions. An increased number of rollers achieves high rigidity. The Model RW uses multiple raceways and small-diameter rollers to increase the overall roller quantity. This achieves much higher rigidity when compared to conventional THK cross roller rings with the same inner and outer dimensions. High Accuracy Wobbling accuracy of 2 μm allows for high rotational accuracy. With the Model RW, it is possible to specify the runout accuracy (wobbling accuracy) of actual operating positions such as machining position and measurement position. Mounting holes in the inner and outer rings reduce the number of design steps and components. The Model RW has mounting holes in the inner and outer rings, eliminating the need for other mounting components and allowing it to attach directly to shafts and housings.
