6202RS Bearing: Features and Applications

The 6202RS bearing is a versatile, single-row deep groove ball bearing with rubber seals on both sides.

Commonly used in electric motors, automotive components, and industrial machinery, this bearing offers durability and reliable performance in various operating conditions.

In this blog, we will focus on the key features and applications of the 6202RS bearing.

What is a 6202RS Bearing?

Structure

• Inner Ring: Fits onto the shaft, allowing it to rotate.
• Outer Ring: Secures into the housing, offering stable support.
• Balls: Contains steel or ceramic balls that roll between the inner and outer rings for smooth movement.
• Cage: Keeps the balls evenly spaced to prevent contact and ensure smooth rotation.
• Seals: The "RS" means the 6202RS bearing has rubber seals on both sides to protect against dirt and moisture while keeping lubrication inside. 

Bearing dimensions and specifications

Using high-quality steel or ceramic enhances the 6202RS bearing's strength and wear resistance. This contributes to a longer service life and improved performance under load.

Additionally, these materials are designed to withstand high temperatures, preventing deformation and failure during extended use, particularly in high-speed applications.

Corrosion resistance is a key feature, as specific materials and surface treatments protect the bearing from moisture and chemicals. This ensures reliable operation over time.

Key Features of the 6202RS Bearing

Sealing Mechanism (2RS)

Importance of Rubber Seals

• Contaminant Protection: The seals prevent dirt, dust, moisture, and other unwanted materials from entering the 6202RS bearing. This protection helps to prevent damage and wear.
• Lubricant Retention: They help hold the lubricant inside the 6202RS bearing, ensuring that the balls and raceways stay lubricated. This reduces friction and wear, leading to smoother operation and a longer lifespan.
• Less Maintenance: The seals keep contaminants out and hold lubrication, reducing the need for frequent maintenance. This is especially useful in hard-to-reach areas.
• Increased Reliability: The seals enhance the bearing's reliability, allowing it to perform well in various conditions. This includes environments where moisture or debris might be present. 

Material Composition

The 6202RS bearing is typically made from Chrome Steel, specifically SAE-52100, a high-carbon, high-chromium alloy.

This material provides excellent corrosion resistance, durability, and high-wear performance, making it ideal for demanding applications.

Precision and Tolerances

ABEC 3 standards, set by the Annular Bearing Engineering Committee, specify tolerances for high accuracy in bearings.

These bearings provide low vibration and reduced friction at moderate to high speeds.

This precision level is suitable for general-purpose and high-performance machinery where reliable accuracy is needed.

Bearings featuring Grade 10 balls are made to high roundness and surface finish standards.

These balls have a deviation of only a few microns, which contributes to consistent, low-friction motion.

This helps extend the 6202RS bearing's life and improve overall stability.

Lubrication

Chevron SRI-2 Grease has a high dropping point and excellent oxidation stability.

This enables it to perform effectively under high temperatures and heavy loads.

Additionally, it contains rust and corrosion inhibitors that protect the 6202RS bearing surfaces.

This protection is effective even in moist or humid environments, preventing degradation over time.

The thick consistency and additives in Chevron SRI-2 reduce wear by forming a protective film on moving parts.

This minimizes metal-to-metal contact and extends the bearing's service life.

This grease also maintains its viscosity well, ensuring that lubrication remains consistent and effective throughout prolonged usage.

Load and Speed Ratings

Load Rating

The bearing’s dynamic load rating indicates how much weight it can handle while in motion.

This makes the 6202RS bearing suitable for light to moderate load applications, such as small motors, appliances, and fans.

Its static load rating indicates how much weight it can support while stationary.

This is useful for setups where moderate loads are applied without frequent movement.

Speed Rating

The 6202RS bearing has a maximum speed rating that defines how fast it can spin without risking wear.

This rating is typically around 15,000 RPM when properly lubricated.

This makes it ideal for moderate-speed applications, such as conveyor rollers or smaller electric motors.

Applications of the 6202RS Bearing

Industrial Uses

• Electric Motors: Supports smooth rotation in small to medium-sized motors, reducing friction for efficient operation.
• Pumps: Provides stability for rotating shafts in centrifugal and positive displacement pumps, ensuring effective fluid movement.
