Lowell 77 Ratchet Clutch, 3-1/8" Square Opening

Robust and dependable for heavy-duty tasks, the Lowell Corporation's Model 77 Mechanical Ratchet Clutches are engineered with standard components like bodies, gears, pawls, and springs. Forces are optimally distributed between the solid steel gear and sturdy pawl, ensuring loads are in compression rather than shear. The gears are made of low-carbon steel, featuring a rugged tooth design for enhanced contact with the pawl. The body comes with mounting holes, and keyways adhere to ANSI/ASME B17.1 standards. Regular lubrication, every 1200 hours, is recommended. Special orders can be placed for specific sizes, shapes, and tooth arrangements. Both fully locked and free running neutral positions are available. Built to last with durable cast iron construction, these clutches also offer customizable models and are proudly made in the USA.
