Bearings are one of the most fundamental components in mechanical engineering, yet choosing the right one can be surprisingly complex. This guide covers everything from the basics — what a bearing is and how it works — to the details that matter most in practice: how to read precision grades and specifications, the five core components that make up a bearing, a breakdown of the most common bearing types, and which industries and machines rely on them most. Whether you're an engineer, a technician, or a procurement specialist, you'll find clear, actionable answers here.
A technical guide for engineers and procurement specialists on selecting self-lubricating bearings — covering DU vs DX specs, PV values, material selection, and wear troubleshooting.
Not sure whether to use a bushing or ball bearing? Compare load capacity, speed, maintenance, and real-world applications to make the right choice.
Bushings (also known as self-lubricating bearings, dry bearings, or oilless bearings) are plain bearings that utilize the inherent self-lubricating properties of their materials to reduce friction. This article consolidates the fundamental definitions, the three-layer structural principles, four structural forms, and common material classifications (such as DU/DX composites) of bushings. It objectively compares the differences between bushings and ball bearings, and provides five key selection criteria—including load capacity and PV value—serving as a practical reference for engineering designers and procurement professionals.
Thrust bearings support axial loads and are primarily available in two types: ball and roller bearings. This guide covers eight topics: definitions and applications, bearing types, structural function, selection factors, product specifications, miniature options, and FAQs. Choosing the right bearing based on load capacity, speed, and installation space is essential for reliable equipment operation.
