A Comprehensive Guide to 6202Z Bearings: Understanding Their Functionality, Benefits, and Applications

Introduction

The 6202Z bearing is a versatile and robust type of bearing widely used in various industrial and automotive applications. It is a deep groove ball bearing, designed to accommodate radial loads and moderate axial loads. With its ability to withstand high speeds and perform reliably under demanding conditions, the 6202Z bearing has become a crucial component in numerous engineering systems.

Design and Functionality

The 6202Z bearing consists of an outer ring, an inner ring, and a ball cage with ball bearings between them. The deep grooves on the inner and outer rings allow the bearing to handle both radial and axial loads. The ball cage ensures the proper spacing and lubrication of the balls, reducing friction and minimizing wear.

Materials and Construction

6202Z bearings are typically made from high-quality steel, providing durability and resistance to wear. The ball bearings are precision-ground and hardened for increased load capacity and long service life. The bearing is also equipped with a metal cage or a polymer cage, depending on the application requirements.

Specifications and Dimensions

The 6202Z bearing conforms to specific dimensions and specifications defined by international standards organizations. Its dimensions include:

• Bore diameter: 15 mm
• Outer diameter: 35 mm
• Width: 11 mm

Load Ratings and Speeds

The load ratings of 6202Z bearings are determined by their dimensions, material, and manufacturing process. The dynamic load rating, which represents the maximum load that the bearing can withstand without permanent deformation, is typically around 7.2 kN. The static load rating, which represents the maximum load that the bearing can withstand without brinelling or permanent indentations, is about 3.9 kN.

The maximum speed at which a 6202Z bearing can operate depends on the application and the lubrication conditions. Generally, it can operate at speeds up to 12,000 rpm under normal lubrication conditions.
