4535 Taper Lock Bushings

The tapered lock bushing has a through-hole length 8 degrees shorter than the diameter of the shaft. It is installed using screws or blind socket head cap screws, driving the bushing into the bore of the assembly and compressing the inner diameter of the bushing to bond the shaft. Tapered Lock Bushings are available in a variety of shaft bore diameters from 1.25″ to 1.25″. Metric apertures are indicated by “MM”. The tapered locking bushing is flush with a pulley or sprocket.
Conical locking bushings are locking mechanisms for power transmission drives. The tapered sections of precision cast iron components are computer etched to identify dimensions. High-strength screws secure the tapered section to the hub, providing a secure clamping fit. This type of locking mechanism is also easy to install and remove, minimizing machining time and avoiding delays. Two types of tapered locking bushings are available: cast iron and stainless steel.

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.

As 1 of the advantages of tapered lock bushings, it is also a very popular choice among wheel nuts. Unlike standard wheel nuts, tapered lock bushings have longer threads that fit into the grooves. Unlike traditional wheel nuts, which require a lot of thread cutting, tapered lock bushings are closer to the axle. The length of the thread is greater than the actual diameter of the bushing, making it more precise.
Another advantage of tapered locking bushings is that they save inventory. Tapered lock bushings are easier to replace than standard bushings because the hub has tapered bores and requires less expensive finishing. These advantages are outweighed by a number of obvious disadvantages. Nonetheless, these advantages are offset by cost savings associated with lower inventory and assembly times.
Another benefit of tapered lock bushing pulleys is that it enables unskilled workers to obtain a shrink-fit on the pulley coupling and shaft. In addition to being an excellent choice for traction applications, tapered lock bushing pulleys are also valuable in solvent plants for improving the quality and efficiency of plant processes. It also increases the durability of the machine.
