Deep groove ball bearing SKF 6209-2Z/C4HT, Outer diameter: 85 mm | Width: 19 mm | Inner diameter: 45 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 ball bearing is designed to meet the demands of high-speed applications while ensuring low rolling resistance. The high-temperature polyurea grease ensures long-lasting lubrication, reducing internal friction and enabling optimal performance, even under conditions of intense heat.

Features:
This single-row deep-groove ball bearing is distinguished by its ability to withstand high radial loads and moderate axial loads, while ensuring minimal friction at high speeds thanks to a significantly increased internal radial clearance (C4). Equipped with two sheet-steel flanges that provide effective sealing against medium-sized particles, it offers better thermal regulation than a bearing with rubber seals, while being ideal for energy-efficient applications. The sheet steel cage offers good impact resistance and can withstand momentary load variations. This bearing is also pre-lubricated with a grease specially designed to withstand high temperatures, enabling smooth rotation without the risk of overheating.

Maintenance:
This bearing requires regular maintenance to ensure optimal performance. It is pre-lubricated with a polyurea-based grease, but relubrication may be necessary, particularly during high-speed operation or in very hot environments. External cleaning of the flanges is also recommended to prevent contamination from debris or dust. It is important to regularly monitor noise levels, temperature, and lubrication to quickly detect any signs of wear or abnormalities.

Sealing:
This SKF bearing features steel sheet flanges that create an effective barrier against medium-sized solid contaminants (debris, chips, gravel, long fibers, etc.). This narrow-gap seal minimizes lubricant loss, ensuring extended service life and continuous protection of the internal components. However, this protection is limited in the event of prolonged exposure to moisture or liquid splashes.

Brand Information:
SKF is a Swedish company founded in 1907 and a global leader in bearings and lubrication systems. An innovator for over 100 years, SKF offers high-quality products designed to improve the efficiency of industrial machinery. Its solutions are used in a wide range of sectors, from aerospace to manufacturing.

Key Features:
- Designed for high-speed applications with increased internal radial clearance (C4).
- Low internal friction to minimize heat and improve energy efficiency.
- Lightweight protection against solid contaminants thanks to steel flanges.
- Pre-lubricated with a high-temperature-resistant polyurea-based grease.

Applications:
This SKF ball bearing is ideal for applications where speed and reduced friction are essential, such as electric motors, fans, and machine tools. It is perfectly suited for low-contamination environments where effective cooling is required. Its narrow-gap sealing makes it particularly suitable for slightly contaminated conditions. It is also recommended for applications where thermal expansion is a critical factor, ensuring a long service life.
