Understanding 6202Z Bearings A Comprehensive Guide

When it comes to machinery and mechanical components, bearings play a crucial role in ensuring smooth operation and reducing friction. One of the most widely used types of bearings is the 6202Z bearing. This article will delve into the specifications, applications, advantages, and maintenance of 6202Z bearings, shedding light on their importance in various industries.

What is a 6202Z Bearing?

The 6202Z bearing is a type of deep groove ball bearing that is known for its versatility and reliability. It typically consists of an inner ring, an outer ring, a cage, and balls that keep the races apart while allowing rotational movement. The designation 6202 refers to the bearing's size and series, while the Z indicates that this bearing has a metal shield on one side. This shield serves as a protective barrier, preventing the ingress of dirt and moisture and retaining lubrication.

Specifications

The 6202Z bearing comes with specific dimensions and load ratings that make it suitable for various applications. Here are some key specifications

- Inner Diameter (ID) 15 mm - Outer Diameter (OD) 35 mm - Width (B) 11 mm - Dynamic Load Rating (C) 6,100 N - Static Load Rating (C0) 3,100 N - Reference Speed Approximately 50,000 RPM

The metal shield (Z) allows for lower friction compared to open bearings, making the 6202Z an excellent choice for applications that require higher speeds.
