The phenomenon that two objects move relative to each other to produce motion resistance between their contact surfaces is called friction, which is called friction. The existence of friction not only increases the power consumption, but also causes the wear of parts' contact surfaces. Therefore, lubricating oil is usually used between the relative moving surfaces of automobile parts to reduce friction. Failure of automotive parts 75% is caused by friction.
Friction can be divided into dry friction, liquid friction, boundary friction and mixed friction according to the lubrication state of the parts.
(1) dry friction
The friction between the frictional surfaces without any lubricating medium is called dry friction.
When the parts are in the state of dry friction, the surface of the parts is abraded sharply, so the surface of the moving parts of the automobile should avoid the occurrence of dry friction as far as possible.
Dry friction and boundary friction are the main friction between the upper part of cylinder wall and piston ring. Dry friction will occur when the journal and bearing are subjected to impact load in the working process.
(2) liquid friction
Two the friction of the friction surface when the lubricant is completely separated is called liquid friction.
In liquid friction, the two friction surfaces are completely separated by a layer of lubricating oil film with a thickness of 1.5-2.0um, which avoids direct contact between the working surfaces of the two parts. Friction only occurs between the lubricating fluid molecules, so the friction resistance is very small, and the wear of the parts is very slight.
Most of the relative motion parts of a car are carried out under the condition of liquid friction (for example, crankshaft and bearing).
(3) boundary friction
Two friction surface separated by a very thin boundary film is called boundary friction.
The oil film thickness is usually below 0.1um. Friction only occurs between the outer molecules of the boundary film, reducing the friction and wear of the parts. But its thickness is very small, and it is easy to be destroyed by impact and high temperature, so it is not as reliable as liquid friction.
For example: between cylinder wall and piston ring; if the work crankshaft and journal between the insufficient supply of lubricant, easy to produce boundary friction.
(4) Mixed friction
The friction between two friction surfaces in the presence of dry friction, liquid friction and boundary friction is called mixed friction.
In the actual working state, the parts usually work under the mixed friction state, and the friction state varies with the working conditions.

In the summer of 1974,
link hidden, please login to view introduced a limited line of MacPherson Strut replacement cartridges, Gas-a-Just and Premium Heavy Duty shock absorbers to North America. Celebrating the Past, Looking to the Future
Surviving the turbulent ‘70s, KYB took full advantage of the economically booming ‘80’s, building a new 500,000-square-foot North American manufacturing plant in Franklin, Indiana just outside Indianapolis. The Franklin plant has been building OE and aftermarket shocks and struts since 1986. It continues to grow with the addition of a research and development lab, “clean” room for assembling shock valving, and most recently, being honored as the 2019 Industrial Plant of the Year for Wastewater Quality for reducing wastewater discharge 40% to the City of Franklin, KYB said.
The next few decades saw growth, with a new office being opened in Addison, Illinois, in 1999, and the launch of highly popular MonoMax truck shock just after the Millenium, according to KYB. In 2008, the company debuted the Strut-Plus complete assembly, which it said helped to set the standard in aftermarket ride control.
2011 saw the opening of a 275,000-square-foot distribution center in Greenwood, Indiana, just up the road from the Franklin manufacturing plant. The close proximity of these two locations allowed for quicker development and manufacturing of new applications and product lines, as well as faster distribution to customers throughout North America. The Addison, Illinois, office was moved to the Greenwood facility in 2014, completing the consolidation of administration, distribution, and manufacturing.
As it celebrates the past and looks to the future, KYB said it continues to grow, with monthly announcements of additional applications and fitments, new product releases, such as KYB JAOS lift kit applications, and a new product line scheduled for release in 2025.

In this aftermarketNews Executive Interview, Johannes Crepon, PDM Automotive Co-Founder & CEO, discusses the company’s platform, how it helps parts suppliers keep their product data up to date, how the use of AI technology makes e-commerce easier for suppliers and distributors, what the company has planned for this year, and more.
aftermarketNews: PDM Automotive provides commerce software for auto parts suppliers, manufacturers, resellers and distributors. Give us a brief overview of how aftermarket companies have found partnering with PDM most beneficial.
link hidden, please login to view Johannes Crepon: The genesis of PDM Automotive was rooted in my own experiences and challenges as the founder of Velocity Automotive, an ecommerce company that sells parts for American cars throughout Europe. At Velocity, we faced difficulties connecting with suppliers, managing product data, and ensuring brand visibility. Recognizing these industry-wide issues, I started PDM Automotive to increase efficiency in the automotive aftermarket through seamless connectivity between suppliers and retailers.
The PDM Automotive platform bridges the gap between auto parts suppliers, manufacturers, resellers and distributors. Manufacturers gain unprecedented transparency into where and how their brands are sold, enabling effective brand management and strategic decision-making. Resellers benefit from expedited access to up-to-date product data, reducing hurdles in acquiring and maintaining catalogs and allowing for agility in responding to market trends.
At its core, PDM Automotive fosters connections and streamlines information flow across the automotive aftermarket. By providing a platform that enhances transparency for manufacturers and accessibility for resellers, we’re creating an ecosystem that elevates the entire industry.
AMN: One of the hallmarks of PDM’s technology is allowing for a “seamless exchange of accurate and timely content across every facet of the automotive industry.” Tell us how PDM assists parts suppliers in keeping their product data up to date. How can the company help suppliers better adhere to ACES & PIES standards?
Crepon: While ACES & PIES has become the most relevant data standard in the Americas, its implementation across the industry has not been without challenges. The standard itself, although comprehensive, does not fully address the intricacies of data exchange, with many resellers interpreting and implementing the standard differently, leading to a fragmented array of data requirements.
Recognizing these challenges, our platform goes beyond merely supporting ACES & PIES standards; we enhance the standards with our proprietary connectors and algorithms, tailoring product data to meet the needs of every receiver. Suppliers can manage their data from a centralized platform, and we tailor this data to comply with the diverse interpretations and requirements of resellers across the industry. This process saves significant time and resources for suppliers and ensures that their product information is accurate, consistent, and easily accessible by resellers and end-users alike.
