All about 6205 bearings

Why choose 6205 ball bearings?

6205 ball bearings are renowned for their robustness and versatility in a wide range of industrial applications. Whether in high-speed or harsh environments, these bearings offer a reliable, high-performance solution. Find out why 6205 bearings are ideal for your mechanical needs.

Technical specifications for 6205 bearings

6205 ball bearings feature standard dimensions: 25mm inside diameter, 52mm outside diameter, and 15mm thickness. These specifications enable them to support heavy loads while ensuring stable, long-lasting performance. These bearings are designed to minimize friction and maximize efficiency, making them essential in many applications.

Types of 6205 bearings

6205 Open bearings

• Application: Ideal for low contamination environments. Allow easy lubrication.

• Benefits: Open design for simplified inspection and maintenance. These bearings are ideal for machines where regular maintenance is possible and easy.

6205 ZZ bearings

• Application: Ideal for moderately contaminated environments, with protective metal flanges.

• Benefits: Enhanced protection against debris and improved durability. Metal flanges help prevent particles from entering the bearing, extending its life.

6205 2RS bearings

• Application: The term '2RS' refers to ball bearings with rubber seals on both sides, providing a seal against splashing water and dust, and allowing higher operating temperatures or speeds.

• Benefits: Excellent sealing against water and contaminants, extending bearing life. Rubber seals on both sides of the bearing provide additional protection against water and dust, ensuring improved functionality in a variety of industrial and domestic applications.

Bearing materials 6205

Chrome-plated steel

• Features: High strength and durability, commonly used for standard, ZZ, and 2RS bearings.

• Applications: Wide range of industrial applications offering reliable performance. Chrome-plated steel is prized for its strength and ability to resist wear.

Stainless steel

• Features: Excellent corrosion resistance, ideal for marine and chemical environments.

• Applications: Used in conditions requiring increased resistance to rust. Stainless steel is ideal for applications where bearings are exposed to corrosive substances.

Ceramic

• Features: Low friction and high heat resistance.

• Applications: Used in high-speed and high-precision applications. Ceramic bearings are often chosen for high-tech equipment where performance is crucial.

Care and maintenance of 6205 bearings

To ensure the longevity and optimum performance of 6205 bearings, follow these practices:

• Lubrication: Use appropriate lubricants to reduce friction and prevent wear. Proper lubrication is essential to keep bearings running smoothly and prevent overheating.

• Regular inspection: Check bearings for wear and damage. Regular inspections can identify potential problems before they become critical.

• Correct installation: Ensure correct installation to avoid misalignment and overstress. Incorrect installation can lead to premature wear and bearing failure.

Purchasing advice for 6205 bearings

When purchasing 6205 bearings, it is important to consider :

• Technical specifications: Make sure dimensions and materials match your specific requirements.

• Operating conditions: Choose the type of bearing (open, ZZ, 2RS) according to the environment in which it will be used.

• Quality and brand: Choose bearings from reputable brands to guarantee superior quality and reliability.

Your questions, our answers

What are the dimensions of a 6205 bearing?
6205 ball bearings have standard dimensions: an inner diameter of 25 mm, an outer diameter of 52 mm, and a thickness of 15 mm. These measurements make them a versatile bearing suitable for a wide range of industrial and mechanical applications.

How do I remove a 6205 bearing?
To extract a 6205 bearing, we recommend using a bearing extractor adapted to its size. This tool enables even force to be applied to the bearing without damaging the shaft or housing. It is important to apply a gradual, controlled force to avoid breaking or deforming the bearing or surrounding components.

How do I insert a 6205 bearing?
When inserting a 6205 bearing, make sure the shaft and housing are clean and free of debris. Use a specific insertion tool or a tube of suitable diameter to apply uniform pressure to the outer ring, avoiding any direct impact on the balls or cages. Make sure the bearing is perfectly aligned to avoid premature wear.

How do I lubricate a 6205 bearing?
Lubrication is essential to prolong the life of 6205 bearings. Use a grease or oil adapted to operating conditions (speed, temperature, environment). If the bearing is fitted with seals (such as the 2RS type), it is often pre-lubricated for life. In the case of open bearings, regular maintenance is required to renew the lubricant.

How to choose a 6205 bearing?
Choosing a 6205 bearing depends on operating conditions:

• Sealing type: Opt for an open bearing if the environment is clean and allows easy lubrication, a ZZ bearing for moderate protection against dust, or a 2RS for maximum sealing against water and dirt.

• Material: Choose a chrome-plated steel bearing for strength and durability, or stainless steel for enhanced resistance to corrosion in damp or chemical environments.

• Brand: Choose recognized brands such as SKF, FAG, NSK, NTN or Timken to guarantee superior quality and reliability.

6205 ball bearings are a robust and reliable option for many industrial and mechanical applications.
