Why engineers and purchasers choose ABCmechanics.com

Every year, new parts are produced. Mechanisms become more complex, improved, and new markings appear. Even professionals find it hard to navigate the vast variety of parts, and searching for the right information takes more and more time.

We created a free system — a reference and information portal where you can find all the necessary information about parts and mechanisms from different manufacturers in just 5 minutes, view their markings, blueprints, existing replacements, and decode manufacturer designations.

Database of bearings, units, belts, seals and linear systems

In our database, we have collected information about mechanical components from various manufacturers, prepared our own blueprints and descriptions that you can use at your convenience.

Currently, our website contains information about the most common and standard parts. Every day, our specialists add new items, expanding our database and improving search and filter technologies. We have gathered manufacturer designation and marking systems from all over the world.

Search for parts by size, description and parameters

The website provides reference guides for searching by size, description, and parameters. Even if you have very little information about the part, we can help you find it.
