4030 Taper Lock Bushings
The tapered lock bushing is an important part of the shaft assembly. These bushings are secured to the shaft using tapered surfaces to provide flexibility between the main and other components. Tapered flanges are machined to ISO standards, while keyways and threads are part of the design. Bushings of this type are also mounted on tapered hubs or shafts. Bushings of this type are used to mechanically connect two or more shafts while still ensuring a tight fit.
When choosing a tapered locking bushing, it is important to pay attention to the size of the bolt holes. Standard sizes are listed in the size chart, but it is important to note that actual bolt holes may vary. Use the size chart to determine the bushing that fits your needs. Applied bushings are made of sintered steel and are guaranteed to meet your demanding applications. You can use grease or oil to protect the bushing and make sure it is in good condition.

The dimension table below shows the standard dimensions of the taper lock bushing, please note that the following figure is the basic dimension required, the actual installation and removal of the bolt holes may vary.

Keyless shaft-to-hub locking devices are another common type. They allow for easy removal and repositioning of components while eliminating gaps and synchronization issues. They also do not require threads, which makes them more economical and popular for low-volume applications. Additionally, they are easier to install and do not require the milling of keyways. As an added bonus, keyless bushings are less expensive and allow for higher shaft tolerances, making them an excellent choice for a variety of applications.
Keyless shaft-to-hub locking devices work by compressing an inner sleeve with a tapered outer and inner diameter. The inner sleeve is installed on the shaft and in the hub hole of the assembly. By tightening the bolts in the locking mechanism, the inner sleeve squeezes and compresses the shaft within the outer diameter of the hub. This ensures a secure connection.
