SUNG-IL MACHINERY CO., LTD is a global leader in precision power transmission components, offering high-performance solutions such as keyless bushings , coupling s, timing pulleys, and support units. Among its most innovative products is the A.P. Lock (Keyless Bushing), designed to deliver secure and efficient shaft-to-hub connections for industrial applications.   What is a Keyless Bushing (A.P. Lock)? A keyless bushing, also known as an A.P. Lock, is a power transmission device that enables shafts and hubs—such as pulleys, gears, and sprockets—to be clamped together using surface pressure instead of traditional keys or splines. This eliminates backlash, improves concentricity, and allows for easier assembly and disassembly compared to conventional keyed connections.   Features of Sung-il Machinery’s A.P. Lock Sung-il Machinery designs its keyless bushings to provide maximum reliability and versatility. Key product features include: Ø   High Clamping Force: Stro...
