Keyless Bushing (Fastening Fittings)（Allowable Torque Range：50.1~70.0）
[What is a keyless bushing (fastening fitting)?]
A keyless bushing is a fastener that can fix shafts and hubs (gear, sprocket, pulley, etc.) without key grooving. By tightening the bolt, drag and friction force are generated in the tapered fitting part, causing it to fasten by the resultant force.
