GM and GP are two types of cage, one with metric measures (GM) and the others with inches measures. The smaller dimensions and the high transmission torque offer some interesting technical and cost-saving solutions. When the application needs torques bigger it is possible to mount more cages side by side. The cage needs one or two bearings for centering, and the two rings (outer and inner) where the cage works must be a surface hardness of 60/62 HRC.
