Understanding the 6205 Bearing

Characteristics and Composition

The 6205 bearing belongs to the deep groove ball bearing family, characterized by its single-row design and deep, uninterrupted raceways. This configuration enables the bearing to accommodate both radial and axial loads while minimizing friction.

The bearing comprises several key components:

• Inner Ring: The inner ring fits snugly onto the shaft, providing a smooth running surface for the rolling elements.
• Outer Ring: The outer ring houses the rolling elements and provides support for the inner ring.
• Rolling Elements: The rolling elements, typically steel balls, facilitate smooth motion by rolling between the inner and outer rings.
• Cage: The cage keeps the rolling elements evenly spaced and prevents them from colliding with each other.

Types and Dimensions

6205 bearings are available in various types, each designed for specific applications:

• Open Bearings: Open bearings lack seals or shields, allowing for easy lubrication and heat dissipation.
• Sealed Bearings: Sealed bearings feature integral seals or shields to protect the internal components from contaminants and moisture.

The dimensions of a 6205 bearing are typically specified as follows:

Material and Heat Treatment

The choice of material and heat treatment process influences the performance and durability of 6205 bearings. Common materials used include:

• Chrome Steel (SUJ2): High strength and wear resistance, suitable for most applications.
• Stainless Steel (440C): Corrosion resistance, suitable for harsh environments.
• Ceramic: Excellent heat resistance and low friction, suitable for high-speed applications.

Applications of 6205 Bearings
