The Ultimate Guide to 6204 Bearing
In this article, Aubearing will help you understand the definition and function of 6204 bearing, structure and characteristics analysis, usage precautions, and its application cases in the steel industry. At the same time, Aubearing will also share how to choose suitable 6204 bearings to improve steel production efficiency. Let us uncover this mysterious bearing together.
6204 bearing is a common deep groove ball bearing, which consists of inner ring, outer ring, steel ball, cage and other components. It has an inner diameter of 20 mm, an outer diameter of 47 mm, and a thickness of 14 mm. This size design allows 6204 bearings to be used in machines of different sizes.

Width of 6204 bearings: The distance between the inner and outer rings of the bearing is 14mm, make sure this size is appropriate for your application to ensure correct installation and operation.
6204 Bearing Dimensions
6204 bearing is a common and widely used bearing model. Understanding its bore, outside diameter and width dimensions is critical to selecting the appropriate bearing. Choose the right size for your application based on your application requirements, load, speed, temperature and quality standards to ensure good performance and reliability.
Composition of 6204 bearings
6204 bearings usually consist of an inner ring, an outer ring, ball elements and a cage. The grooves in the raceway are slightly larger than the radius of the steel ball. Since the steel ball and the raceway are in point contact, the 6204 bearing can bear both axial loads in both directions and radial loads. Generally, they are usually used in pairs to minimize the internal axial force caused by the load and mainly bear the radial load.
Steel balls are spherical components used as rolling mechanisms in rotating moving parts such as bearings, tools, and wheels. There are many specifications and sizes for various purposes. Steel balls play the most crucial role in performing functions. The most important purpose is that it represents the importance of the rolling and rotational aspects of the bearing. Without it, the bearing may not rotate in any direction.
Bearing cage is simply called a bearing separator or cage; it is the component in a ball bearing that separates the balls, rollers, or needle rollers and keeps them evenly spaced radially, and holds the bearings together. The cage holds the balls in uniform rings so that they are equally spaced within the bearing. It can be manufactured into a variety of shapes and developed using low-friction materials, allowing the ball to continue rolling efficiently. The materials of bearing cages include: steel bearing cages, ceramic bearing cages, plastic bearing cages, etc.
Steel ring. Its main purpose is to basically act like a path, allowing the balls inside the ball bearing to slide without friction. Simply put, ball bearings require a race to control the individual balls, and it provides a fixed path for the balls to roll.
6204 Bearing Material
Chrome steel (GCr15)
Chromium steel is the most common material used to produce precision load-bearing components for ball bearings, and it offers a cost-effective alternative to stainless steel. Although chromium steel is less resistant to corrosion, it is durable and can still resist corrosive factors in certain environments.
Stainless steel (SS)
Stainless steel 6204 bearings offer several significant advantages. Because stainless steel in particular has greater chemical and corrosion resistance, as well as better stability in high-temperature environments. Stainless steel bearings have the same deep grooves and tight fit between raceways and balls as standard deep groove ball bearings made of carbon chromium steel.
Ceramic
Ceramic ball bearings are made of ceramic materials. The inner ring, outer ring and balls are made of silicon nitride (Si3N4) or zirconium oxide (ZrO2). It has higher hardness and better elasticity than chromium steel bearings. In addition, ceramic ball bearings can run completely dry without lubricating oil, have excellent corrosion resistance, can run in concentrated acids, and will not corrode when fully immersed in seawater. Also suitable for temperature changes, ceramic bearings have a much longer life cycle than steel bearings.
Three types of 6204 bearings
There are three main types of 6204 bearing seals: open, ZZ, and 2RS.
6204 OPEN type bearing cover is a coverless design, allowing the internal components of the bearing to be exposed to the external environment. This design makes the bearings susceptible to contamination from dirt, dust, and other external particles. Therefore, type 6204 OPEN bearings are suitable for clean environments or applications that require regular cleaning.
6204ZZ means that the outer cover has a metal shield. The metal shield effectively blocks the entry of dust, contaminants and other external particles while retaining lubricant within the bearing.
6204 RS means the outer cover uses a rubber seal. Rubber seals effectively block the entry of moisture, dust and other contaminants, providing enhanced protection. This type of sealing is often used in harsh environments and applications that require stringent protection.
