Bearing temperature rise Heat dissipation rate SKF 61906 Deep groove ball bearings

Deep groove ball bearing with seals or shields

Single row deep groove ball bearings with seals or shields are particularly versatile, have low friction and are optimized for low noise and low vibration, which enables high rotational speeds. 

They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than many other bearing types. 

The integral sealing can significantly prolong bearing service life because it keeps lubricant in the bearings and contaminants out. 

Integral sealing prolongs bearing service life, simple, versatile, robust design low friction, high-speed  makes radial and axial load in both directions, so it requires little maintenance.

Knowledge and introduction of bearings                                                                                                      

The SKF 61906 is a single-row deep groove ball bearing that provides versatility by handling both radial and axial loads in either direction. 

With a compact design, it is particularly suited for applications where space and weight are important considerations.

Key Features:

Design:

Single-row configuration: The 61906 features a single row of balls, which makes it compact and ideal for applications with limited space.

Deep groove design: This design allows the bearing to accommodate radial and axial loads, making it versatile for various types of applications.

Standard tolerances: SKF deep groove ball bearings are manufactured to meet strict tolerance standards for consistent and reliable performance.

Material:

Typically made from high-quality, high-carbon chromium steel, SKF 61906 bearings are highly resistant to wear and provide long-lasting durability. 

Some versions may include special coatings or surface treatments for increased protection against corrosion.

Sealing Options:

Open type: No seals or shields, allowing easy access to the bearing for lubrication and maintenance.

Sealed (2RS): Rubber seals on both sides to protect against dirt, moisture, and contaminants while retaining lubrication.

Shielded (2Z): Metal shields on both sides that provide a similar protection level as sealed bearings but with lower friction.

Performance:

High-speed operation: The 61906 bearing is designed for high-speed rotations and low friction, making it suitable for applications such as electric motors and machine tools.

Low friction: The design reduces internal friction, enhancing energy efficiency and extending the bearing's lifespan.

Quiet operation: SKF’s high manufacturing standards ensure smooth and silent operation, which is crucial in noise-sensitive applications.

Applications:

Electric motors (including power tools, fans, and pumps)

Automotive components (e.g., wheel hubs, alternators, gearboxes)

Office equipment (e.g., printers and copiers)

Home appliances (e.g., washing machines, refrigerators)

HVAC systems

Medical devices

The bearing is also suitable for industries where consistent, low-maintenance operation is necessary, such as in consumer electronics and industrial machinery.

Technical Specifications:

Internal design: The deep groove design allows the bearing to handle both radial and axial loads in both directions.

Dimensions:

Bore diameter: 30 mm

Outer diameter: 47 mm

Width: 9 mm

The bearing’s compact size makes it ideal for space-constrained environments while maintaining a high load-bearing capacity.

Speed ratings: The bearing is designed to operate efficiently at moderate to high speeds, depending on the lubrication and load conditions.

Load capacity: It can carry moderate radial loads and axial loads in both directions, with an optimized design for continuous and high-speed use.

Advantages:

Compact design: The 61906 offers a smaller footprint, which is ideal for applications where space is limited.

Versatility: Handles both radial and axial loads, making it suitable for a broad range of applications.

Low maintenance: With proper sealing options (e.g., sealed or shielded variants), it can operate for extended periods with minimal need for maintenance.

Energy-efficient: The low friction design reduces energy losses and improves overall efficiency in machinery.
