Deep groove ball bearing SKF 6311-Z, Outer diameter: 120 mm | Width: 29 mm | Inner diameter: 55 mm

Ball bearings are essential mechanical components that reduce friction and support various loads in a wide range of industrial applications. Among them, deep groove ball bearings stand out for their versatility, ability to operate at high speeds, and low maintenance requirements.

This SKF-brand deep groove ball bearing is designed to withstand radial and axial loads in both directions, while being easy to install. Its metal shield provides effective protection against large debris, while its sheet steel cage and standard radial clearance make it a reliable solution for a variety of high-speed applications.

Features:
This single-row deep groove ball bearing provides high radial load capacity and moderate axial load capacity in both directions. The metal shield on one side provides effective protection against large debris while minimizing the impact on friction. Its sheet steel cage and internal radial clearance (CN) allow for smooth operation and high rotational speeds. This bearing tolerates moderate operating temperatures while ensuring good thermal stability in most common applications.

Maintenance:
This bearing requires little maintenance. The metal shield partially retains the lubricant on one side, while the opening on the other side allows for easy relubrication if necessary. To ensure optimal operation, it is essential to select a lubricant suitable for the bearing’s specific operating conditions. The deflector also helps protect the closed side from medium- and large-sized contaminants, which extends the bearing’s service life and improves its reliability. However, it is always advisable to monitor other operating parameters such as noise, temperature, and vibration. These regular checks allow for the rapid detection of any signs of malfunction.

Sealing:
This bearing is equipped with a metal deflector on one side, which forms an effective barrier against large contaminants. The sheet-steel deflector is inserted into the outer ring and creates a narrow gap with the inner ring, thereby limiting the entry of contaminants.

Brand Information:
SKF (Svenska Kullager-Fabriken) is a Swedish multinational group founded in 1907 and a world leader in the field of mechanical bearings. SKF is one of the world’s leading suppliers of bearings, seals, mechatronic components, lubrication systems, and services designed to improve the reliability of rotating equipment and ensure its performance. SKF products can be used wherever there is motion. They are used in some 40 industrial sectors, including automotive, aerospace, rail, manufacturing, food and beverage, medical, traditional and renewable energy, and agriculture.

Key Strengths:
- Ability to withstand high radial loads and moderate axial loads, offering great flexibility of use;
- Single-sided metal shield providing protection against large debris without any loss of efficiency due to friction;
- Suitable for high-speed applications while maintaining moderate friction and noise levels;
- Robust sheet steel construction, ensuring good resistance to impacts and peak loads.

Applications:
This bearing is ideally suited for industrial environments requiring high radial load capacity, such as conveyors and material handling equipment. It is also ideal for agricultural machinery that requires high durability as well as resistance to vibrations and shocks. In addition, this product can be used in warehouse logistics systems and production lines where medium to high rotational speeds are frequently required. These bearings also ensure reliable performance for agricultural equipment and small- to medium-sized machine tools.
