Rotary Power manufactures two kinds of radial piston motors. The first, a typical cam motor (our XJ, XF and XL motors) that consists of multiple pistons fed under pressure following an external cam track. The second is an eccentric piston motor (our SMA motor) where the pistons drive an eccentric shaft. Our cam motor ranges offer a diverse variety of options and displacements with a modular design, enabling both flexibility and standardization throughout the range.
