Bottom Bracket Standards and Terminology

PF42 (also known as BB30 BB30a BB30ai BBright™ Direct Fit) The term PF42 refers to the inside diameter of the shell The term BB30 was an early term in the history of this standard and refers to the 30mm diameter of the spindle used at that time However bottom bracket bearings are available in this standard for 28 99mm 24mm and 22/24mm spindle systems

Types Of Synchronous Belt Profiles and Nomenclature

Nowadays there are three common types of synchronous belts based on their curvilinear profiles: H-type S-type R-type H-TYPE The H-type tooth profile is referred to as HTD It has a round tooth profile and its shape is defined by a group of radii centered a specific distance from the pitch line of the belt

Recorded Webinars

Bearing Nomenclature Description: This webinar is designed to provide a guide to the understanding of the basic rolling element bearing part number system used for primary bearing types and how special features of the bearing are described using prefixes and suffixes It will demonstrate that while bearing manufacturers using the ISO numbering system will have similar basic part numbers they

What is Bearing? What are Main Types of Bearings?

Today we will learn about bearing and types of bearings Bearing is a machine element that have constrained relative motions and used to reduces friction between moving parts of machine to obtain desired motion or we can say that the machine elements which are support the rotating parts of a machine and reduce friction are called bearings
