Are you currently trying to find the right bushings for a particular application? As a type of hardware that is frequently used in machinery, there are a wide range of bushings to choose from. Each option is built to help reduce noise and vibration, but many have unique features or requirements that can help you decide which is the correct fit. Aside from choosing the correct dimensions, it is also important to consider how lubrication, material, style, alignment capabilities, and line reaming requirements may affect your operations. While most bushings look fairly similar, with a cylindrically-shaped sleeve incorporating a “wall”, they are available in an array of variations. In this blog, we will outline several aspects you should take into account when choosing the right bushing for your machinery.

Across most industries, machinery relies on the use of rotating shafts for rotary motion of certain components. In aviation, this is commonplace in parts like the engine, allowing for controlled movement. That being said, rotary shafts often require additional support for stability, so bearings are used to constrain motion and reduce friction without impeding the proper motions of shaft mechanisms. In particular, such situations call for the employment of a pillow block bearing, those of which are bearings specifically fabricated to support rotary shafts. With a unique three-part design, they are helpful part types for various applications. For your better knowledge, we will further explore the working principles of pillow block bearings in the following blog.

Sprockets are versatile components that find use in a wide variety of applications, ranging from bicycles to agriculture equipment and tracked vehicles. Although the operating principle remains the same amongst all variants, sprockets can be explicitly manufactured to be compatible with the system in question. In general, sprockets can be classified as being Type A, B, C, or D. This classification system helps broadly categorize sprockets by similar functions, but does very little to describe the particular applications in which each may be used. Therefore, this blog will detail the sixteen most common sprocket types, helping customers choose which is most appropriate for their needs.

A typical aircraft jet engine consists of many different parts, each serving a distinct role that allows for overall operations to be carried out with ease. O-rings are a small, yet important, element of jet engines, coming in the form of ring-shaped, elastomeric mechanical seals that are compressed between components for the means of preventing leaks. O-rings can come in many shapes and types, allowing them to be implemented in systems where they prevent the leaking of oil, water, sewage, and other various fluids. In this blog, we will discuss the application of O-rings for jet engines specifically, allowing you to better understand how they aid in upholding operations.
