According to U.S. Tsubaki, its extensive POWER-LOCK portfolio offers a simple and cost-effective solution to problems associated with keyed or machined drive shafts. Incorporating POWER-LOCK technology into existing and new designs provides increased shaft strength while reducing machining and maintenance costs. The company notes that POWER-LOCK eliminates backlash damage to keyways and specialty machined bores in applications that experience reversing loads or high torque. In addition, machining expenses associated with keyways, spline bores, steps and snap ring grooves can be removed from the equation. The easy-to-install device is suitable for locking large or small sprockets, gears, pulleys, timing cams and rollers.
