What Are Common Types of Bearings and Bushings?

Bearings and bushings are integral to the smooth operation of countless mechanical systems, specifically being designed to reduce friction and wear of rotating and moving parts while offering them support. While a bushing is technically just a type of bearing, its distinctive design and capabilities often have it considered its own part type for the purposes of discussing operational requirements. In order to help those in search of reliable hardware solutions, we will explore the most popular options and their respective applications in this blog, so read on to learn more.

What Are Common Types of Bearings and Their Applications?

Bearings are found in systems ranging from industrial machinery to aerospace equipment, coming in various forms to reduce friction and guide motion. Below are some of the most common types and their respective uses:

• Ball Bearings: As the most prevalent option across applications, these bearings feature rolling balls between two races that assist in friction reduction and load bearing. Ball bearings are capable of supporting both radial and axial loads, making them common in automotive parts, electric motors, and industrial machinery. Many aerospace bearings are of this category as well, where the use of rollers provides optimal performance even under extreme stress.
• Roller Bearings: Roller bearings are designed for heavy-duty applications, featuring cylindrical or tapered rolling elements that provide increased axial and radial load bearing capabilities. Tapered roller bearings in particular are useful for wheel hubs, gearboxes, and other automotive assemblies, as well as heavy machinery and construction equipment.
• Needle Bearings: As a subtype of roller bearings, this category is distinguishable by the presence of long, thin, and cylindrical rollers that offer high load-carrying capacities while remaining quite compact. This allows needle bearings to excel within automotive and industrial machinery, where their small form factor is highly desirable.
• Thrust Bearings: These bearings are specifically suited for accommodating axial loads that act parallel to a shaft, driving their presence in automotive transmissions, pumps, and gearboxes. In such settings, thrust bearings support rotating components while upholding smooth motion.

What Are Common Types of Bushings and Their Applications?

Bushings differ from bearings with a lack of rolling elements, instead reducing wear and absorbing vibration through sliding motions and unique design features. Below are some of the most common types of bushings and their applications:

• Sleeve Bushings: Also known as plain or sleeve bearings, this category comprises basic bushings that feature the typical cylindrical shape that permits sliding and rotating within a housing. Sleeve bushings are widely used in automotive suspension systems, agricultural machinery, and electrical equipment, where their simple and cost-effective design promotes versatility.
• Flanged Bushings: While having a standard cylindrical design, these bushings feature a distinct flange or lip at one end that offers additional support to an assembly. This design prevents the bushing from moving axially within a housing, facilitating the management of axial movement. Generally, one will most often find flanged bushings in automotive, industrial, and construction equipment for smoothing out operations and reducing wear.
• Tapered Bushings: Designed with a conical shape that fits into a matching tapered hole, these bushings provide a locking mechanism for rotating parts. With the ability to enhance connections between shafts and components, tapered bushings are a good choice for securing pulleys, sprockets, power transmission systems, and other such equipment.
• Aviation Bushings: As a more broad and specialized category, aviation bushings are those that leverage composites, advanced alloys, and other materials that guarantee reliability under the stress of extreme temperatures, pressures, and vibration. Aviation bushings are used in aircraft landing gear, control systems, and engines, often meeting exacting industry specifications for interchangeability and performance.
