Keyless Bushing (Fastening Fittings)（Type：Sleeve）
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.

FAQ Keyless Bushing (Fastening Fittings)
- Question: What is a Keyless Bushing and how does it work?
- Answer: A Keyless Bushing is a mechanical component used for fastening fittings, providing a secure connection between shafts and hubs without the need for traditional keys. It utilizes frictional forces to securely grip the shaft and hub, ensuring a backlash-free fit.
- Question: What are the benefits of using Keyless Bushings?
- Answer: Keyless Bushings offer several advantages, including simplified installation without the need for keyways, reduced maintenance time and costs, and enhanced reliability due to their secure locking mechanisms. They also provide precise and backlash-free shaft-to-hub connections.
- Question: How do I install a Keyless Bushing?
- Answer: Installing a Keyless Bushing is straightforward. Simply slide the bushing onto the shaft and tighten the locking screws to achieve a secure grip between the shaft and the hub. Detailed installation instructions can be found in the product manual.
- Question: Can Keyless Bushings be used in high-speed applications?
- Answer: Yes, Keyless Bushings are suitable for use in high-speed applications. They are engineered to provide secure and reliable shaft-to-hub connections even under high rotational speeds, ensuring smooth operation and minimal vibration.
