Keyless Bushing (Fastening Fittings)（Allowable Torque Range：150.1~200.0）

An online store for keyless bushings (fastening fittings). In MISUMI's e-catalog, specifications and dimensions such as the shaft hole diameter, allowable torque, main body material, surface processing, boss diameter and delivery date can be selected in single clicks, making it easy to find the desired keyless bushing.

[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.
