A motorcycle crankshaft bearing plays a fundamental role in supporting crankshaft rotation, reducing friction, and maintaining engine stability under high-speed and high-load conditions. This in-depth guide explains how crankshaft bearings directly influence engine performance, efficiency, vibration control, and long-term durability. You will also learn about bearing types, failure causes, maintenance tips, and how to select the right bearing for your motorcycle engine, with industry insights from BMT.

​Angular Contact Ball Bearings are essential components in modern mechanical systems where high speed, precision, and combined axial and radial load capacity are required. This article provides a comprehensive explanation of what angular contact ball bearings are, how they work, why they outperform standard bearings in demanding applications, and how to select the right type for your machinery. Drawing on industry practices and technical standards, this guide is designed to support engineers, buyers, and decision-makers seeking reliable bearing solutions from trusted manufacturers like BMT.

Choosing the right thrust ball bearings is not just a technical decision—it directly impacts equipment efficiency, operational stability, and long-term maintenance costs. In this in-depth guide, I’ll walk you through how thrust ball bearings work, their structural types, key selection criteria, industry applications, and common mistakes buyers make.

​Whether it's international or national standards, bearing failures are broadly classified into six main categories. Here, I can suggest a few classifications for you. First, failures originating from within the bearing steel; second, failures originating from the surface of the bearing steel. This article mainly analyzes failures originating from the outside.

​Let's start from the beginning. Once a motor overheats, the first thing an engineer does is to determine where the heat is coming from. The main components of the motor system are the targets for investigation. Therefore, we need to understand the possible overheating locations or the locations where overheating has been measured.

In the world of bearings, there is a parameter that is invisible and intangible, yet directly affects the operating state of the bearing and even the stability of the entire equipment: bearing clearance.
