Understanding the Specifications of 6204 Bearings

Bearings are crucial components in various machinery, playing a vital role in the smooth operation of mechanical systems. One common type of bearing widely used in diverse applications is the 6204 bearing. These deep groove ball bearings are renowned for their versatility and reliability. In this article, we will delve into the specifications of the 6204 bearing, its applications, advantages, and installation considerations.

Specifications Overview

The 6204 bearing is categorized under the deep groove ball bearings, a design that allows for radial and axial loads. The core specifications of the 6204 bearing are as follows

- Inner Diameter (ID) 20 mm - Outer Diameter (OD) 47 mm - Width (W) 14 mm - Dynamic Load Rating (C) Approximately 6,300 N - Static Load Rating (C0) Approximately 3,600 N - Maximum Speed Rating Dependent on the lubrication and operating conditions, typically around 12,000 RPM. - Material Usually formed from high-carbon chrome steel or stainless steel, offering excellent strength and corrosion resistance.

The 6204 bearing may also come in various designs, including those with rubber seals (6204-2RS) that provide protection against dust and moisture, and those with metal shields (6204-Z) that enhance durability while reducing friction.

6204 bearings are extensively used in numerous applications due to their robust design. Common uses include

1. Electric Motors Their ability to handle varying load and speed conditions makes them ideal for electric motor applications. 2. Automotive Applications Found in alternators, starters, and gearboxes, 6204 bearings are critical for automotive performance. 3. Industrial Machines Used in conveyors, pumps, and compressors, they ensure seamless operation in manufacturing processes. 4. Household Appliances Present in washing machines, dryers, and vacuum cleaners, these bearings contribute to the efficient operation of everyday devices.
