With China's new export restrictions on rare earth magnets, there have been questions on how this will affect Ogura's PTO clutch brakes. These clutches are used in a variety of outdoor power applications including lawn care equipment, portable sawmills, agricultural equipment, stump grinders, concrete saws, floor care equipment, and more. Ogura PTO clutch brakes serve two main purposes in motion control. When power is applied to the electromagnetic clutch, the clutch coil is energized, and the clutch engages to transfer torque from the engine to the rotating device such as cutting blades on a zero-turn lawn mower. When power is removed, the clutch disengages, and the brake portion of the device then engages to slow the blades for safety. Outside of popular lawn mower applications, the same concept holds true for stump grinders, concrete saws, etc.

Unlike other PTO clutch brakes made by our competitors, Ogura has a unique design and construction that avoids using rare earth magnets to generate the braking torque which is critical for safety applications. For several decades, Ogura has used a robust spring design to mechanically generate the brake torque instead of using rare earth magnets for braking torque. Because the Ogura braking torque is generated mechanically, the design is not subjected to the current supply chain issues or the degradation of magnet strength with higher operating temperatures. In addition, the Ogura design does not rely on magnetic airgaps which grow with wear and can cause sudden non-performance of the brake function. The wear on an Ogura PTO clutch brake is gradual and predictable, offering best in class safety for the consumer and equipment operator. Rest assured that the worldwide commotion over the rare earth magnet supply chain will not affect the PTO clutch brakes made by Ogura. You can expect the same performance, leading design, and availability that the industry has come to know and admire. Thank you for choosing to use Ogura PTO clutch brakes on your equipment.

Ogura PTO clutch brakes and General Purpose clutches are commonly mounted on engine shafts and are rated for static clutch torque of roughly 100 to 400 lb-ft. They are available in various pulley configurations and hub versions as well to accept a custom pulley, sprocket or coupling. These durable components have been proven in numerous rugged applications over the years and new applications continue to arise. One-piece designs with solid rotors make for easy installation and long life. Benefits of using an Ogura PTO clutch brake:

• Long life
• Safety
• Built for outdoor operation
• Many years of proven success
• For use with operator presence controls
• Available with a soft start controller
• Custom designs available based on minimum order quantities
