120100 Taper Lock Bushings

The Taper-Lock bushing system makes the sprocket hub narrower than ever, while the left-aligned hub design keeps the shaft closer to the bearing and eliminates issues associated with high overhung loads. The gradual taper of the bushing makes it a perfect fit and provides the equivalent of a shrink fit. However, the benefits don’t stop there! In addition to low overhung load capacity, they also offer high precision.
Another common application for tapered bushings is in power transmission components. The tapered shafts of these devices are attached to rollers or pulleys. Wedge-action tapered grips lock them in place without deforming the shaft. These tapered bushings are generally available in QD and Taper-Lock styles. While both styles are very effective, each should be used sparingly.

Taper Lock Bushing Size Chart

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.

Tapered locking bushings have an 8-degree taper to reduce through-hole length. Internal screws hold the bushing in place and give it a thinner profile than flanged bushings. To use a tapered lock bushing, make sure the hub diameter of the assembly matches the shaft hole size. Thorough cleaning of the bushing before installation is critical.
Tapered locking bushings are typically used for tapered assemblies. This flange-like device is used to mount different elements of a transmission, such as chains, belts, pulleys, or gears. The sleeve is manufactured to ISO standards. You will need to order the appropriate tapered lock bushing separately from the hub and axle assembly. The benefits of using tapered locking bushing are numerous.
The size chart below provides standard sizes of tapered lock bushings. While this chart helps meet basic dimensional requirements, it is important to note that actual bolt holes may differ from those in the dimensional chart. Listed here are a few important details to keep in mind before purchasing a tapered locking bushing. The information in this article may be out of date or inaccurate. Please contact the manufacturer for the latest information.
Tapered lock bushings are 1 of the most common types of flangeless bushings. Bushings of this type are made of precision cast iron. It is computer etched for size identification. High-strength screws attach the tapered portion of the assembly to the hub. This strong connection allows the transmission of high torques. In sprocket installation, tapered lock bushings ensure proper sprocket installation and easy alignment.
