Structural features:
1. One-piece fully enclosed helical gear transmission structure: higher dustproof performance and operational stability, longer service life and better user experience;
2. Universal installation dimensions of the whole series: RY130, RY160, RY220 series of universal dimensions of the rear chuck, saving the cost of bed management for each user;
3. The whole of the fine grinding chuck: The whole of the chuck is used as the reference surface for installation and positioning, which is convenient for users to install and debug;
4. Internal front cylinder transmission structure: the cylinder is directly pushed, and the clamping force is stable and reliable with the change of air pressure, which provides the basis for high bearing capacity performance;
5. Fully-sealed design of jaws: RY130. RY160. RY220 series barrel rear chuck has unique fully-sealed jaws, which reduces the possibility of jamming and reduces the need for manual maintenance.
