Sleeve bearings and bushings are two commonly used terms in rotating and linear motion systems. While often used interchangeably, they have subtle differences in design, application, and terminology. This guide will explain what sleeve bearings and bushings are, describes their common types and materials, and provide a direct comparison to […]

Needle roller bearings are widely used in automotive, industrial machinery, and aerospace applications due to their high load-carrying capacity in compact radial dimensions. A needle roller bearing size chart provides essential dimensional and performance data for selecting the correct bearing. DUHUI will present complete size charts for drawn cup, machined

Wheel bearings are fundamental to vehicle safety and ride comfort. Drivers often encounter humming noises, vibration, or wheel play—symptoms that point directly to a failing wheel bearing. Yet not all wheel bearings are the same. Understanding the types of wheel bearings used in modern vehicles helps mechanics and vehicle owners

Wheel hubs are the critical interface between a vehicle’s wheels and its suspension or drivetrain. Without a properly functioning wheel hub, the wheel cannot rotate smoothly, carry the vehicle’s weight, or maintain alignment. DUHUI will explain what wheel hubs are, where they are located, how they work together with the

Are you hearing a humming noise from your wheel, feeling vibration through the steering wheel, or seeing an ABS warning light? These signs often point to a failing wheel bearing or hub assembly. Before you install a new replacement hub assembly, there are several technical factors that affect safety, performance,
