Sealed Bearings for Durability Open Ball Bearings SKF 61868 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.

SKF 61868 Deep Groove Ball Bearing

1. Design & Construction:

Deep Groove Design: The SKF 61868 features a deep groove raceway, which enables it to handle both radial and axial loads in both directions, 

offering increased load capacity and versatility in different applications.

Single-Row Configuration: It is a single-row bearing, which provides a compact design and is ideal for space-limited installations.

Open Design: The bearing has an open design, meaning it does not feature seals or shields. This allows for the use of high-quality lubricants and reduces friction, 

which is beneficial in high-speed operations. However, it also requires a clean operating environment to avoid contamination.

2. Material:

SKF uses premium-quality bearing steel for the 61868 bearing, ensuring durability and resistance to wear, fatigue, and corrosion. 

This material choice contributes to the bearing's long service life and reliability.

3. Performance Characteristics

High-Speed Capability: Like other SKF deep groove ball bearings, the 61868 is engineered to handle high rotational speeds, with minimal friction. 

This makes it suitable for applications that require fast, consistent movement.

Low Noise and Vibration: The precision manufacturing of the bearing ensures low noise and vibration during operation, 

which is particularly important in high-speed machinery and equipment.

Versatility: The deep groove design allows it to perform well in both radial and axial load applications, providing flexibility across various types of machinery.

4. Applications:

Electric Motors: The 61868 is often used in electric motors where smooth, high-speed operation is essential.

Fans & Pumps: Due to its high-speed characteristics and efficient load handling, it’s suitable for fans, blowers, and pump systems.

Machine Tools: It is commonly employed in machine tools that require precision, high-speed movement, and durability.

Agricultural and Construction Equipment: The 61868 bearing can also be found in agricultural machinery, construction equipment, 

and other heavy-duty machines that operate under varying loads and conditions.

Industrial Applications: It’s used in a broad range of industrial equipment, such as conveyors, compressors, and robotics.

5. Advantages:

High Load Capacity: The 61868 can support both axial and radial loads, making it versatile for various applications.

High-Speed Operation: Its low-friction design enables high-speed operation, which reduces energy consumption and wear.

Durability: SKF’s high manufacturing standards ensure that the 61868 bearing offers excellent durability and long service life in demanding conditions.

Compact Design: The bearing’s compact size makes it suitable for space-constrained environments, while still offering robust performance.

Ease of Maintenance: As an open bearing, it allows for easier lubrication and maintenance in clean environments.
