The Slide-Rite gearbox offers leakproof performance with low backlash. At low speed operation, it offers a substantially higher torque output yet is capable of running at more than twice the speed of the Float-A-Shaft design. A one-piece housing design eliminates leakage and is prelubricated, ready for installation. Bores are ground to 0.002' total tolerance. Rated for a maximum of 1200 RPM.
