Bushing VS Bearings

Bushing vs Bearing – Which Do You Choose ?

Provide Custom Design, Cost-Effective & Reliable Bushings and Bearings Solutions.

• Bushing

A bushing might also be called a sleeve bearing. However, the term sleeve bushing would be redundant. Thus, a bushing is a bearing, but a bearing is not necessarily a bushing type. Bushings slide over smooth rods and provide an extremely low friction motion which minimizes power consumption, noise, and wear on parts. Bushings look like plain metal tubes, but they are actually fairly sophisticated parts.

The bushings are self-lubricating and therefore ideal for low-maintenance or maintenance-free operation. Self-lubrication is achieved by a uniform pattern of depressions on the surface of the bushing that serve as grease reservoirs. Some nylon bushings operate without the use of lubricants and are particularly useful in the food and textile industries where dry applications are preferred.

• Bearing

A bearing is the general term for something that allows relative motion between two components, surfaces, etc.

Bearings are tribological components that carry a load while in contact and moving relative to another part. The movement can be sliding or rotating. There are basically two different types of bearings: plain bearings and roller bearings. Other types include fluid bearings that support their loads on a thin layer of gas or liquid; magnetic bearings that use magnetic fields to carry their loads; hinged bending bearings in which the load is supported by a bending member; and jewel bearings used in watches and clocks.

• What is the difference between a bushing and a bearing?

A bearing is designed to “bear” or carry stress or loads in various design applications, but to add a layer of confusion, bushings are often referred to as plain bearings or sleeve bearings. Generally speaking, the difference between bushings and rolling element bearings in that bushings are designed as a single part, while bearings can have multiple parts.

A bushing is a round shaped cylindrical component. It is either equipped with rolling elements (ball, roller) or not and mainly used as a support component in an assembly to reduce machine wear out and for smooth operation. Its primary use is static (support) or dynamic (motion). On the other hand, a bearing is a machine element used for moving parts specifically for dynamic (motion) such as radial bearings and linear bearings.

• The common point both bushings vs bearings

Both bearings and bushings can be composed of metal or plastic composites, or a combination of the two. Plastic bearings provide the advantages of a self-lubricating design(never needs grease), plus corrosion and chemical resistance, and superior longevity and wear.

• Types of bushings vs bearings

There are several bushing types on the market with different material compositions. Some can withstand corrosion, whereas others are suitable for controlling high pressure and impact. Select the best bushing type based on the application and operating environment.

• Bronze bushings

Bronze bushings are typically made from a continuous casting of bronze material to ensure a uniform bronze structure throughout the bushing. These are general purpose bushings that provide excellent load-carrying capacity and wear protection. They can handle high levels of heat and withstand temperatures up to 450 ° F. They can be easily modified by adding oil and grease grooves and self-lubricating graphite plugs. Bronze bushings can also be flanged to withstand combined loads.

• Plastic bushings
