Deep groove ball bearing SKF 6305-2RS1/C3GJN, Outer diameter: 62 mm | Width: 17 mm | Inner diameter: 25 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.

SKF brand deep groove ball bearings are designed to withstand radial and axial loads in both directions. Practical and easy to install, they stand out for their ability to operate efficiently even under varying temperature conditions or in dusty and humid environments. Thanks to a reinforced design and seals, this product ensures increased durability and requires little maintenance, offering a reliable solution for various industrial equipment.

Features:
This SKF deep groove ball bearing model is made of sheet steel, a material that ensures optimal strength and impact resistance. Its internal radial clearance is C3, meaning the bearing has a slight additional space between the balls and the raceway, thereby reducing internal friction and allowing for operation at high speeds. Rubber seals on both sides provide enhanced protection against contaminant ingress while retaining the lubricant inside. This bearing is greased with a polyurea-thickened oil, a lubricant specially adapted for extreme conditions, offering an operating temperature range from -30°C to +150°C.

Maintenance:
Thanks to its sealed design and rubber seals, this SKF deep groove ball bearing requires little maintenance. Its specialized lubricant, a polyurea-thickened grease (NLGI Class 2), provides optimal protection for use in extreme temperature ranges from -30°C to +150°C and also offers excellent thermal and chemical stability. However, periodic monitoring of noise levels, vibrations, and temperature helps ensure continuous performance and an extended service life for the bearing.

Sealing:
This bearing is equipped with nitrile-butadiene (NBR) lip seals on both sides, forming an effective barrier against dust, water, and contaminants. This oil- and grease-resistant material protects the bearing from contamination while retaining the lubricant inside, making it ideal for dusty or humid environments. The complete sealing helps protect the bearing, extending its service life while maintaining optimal performance under the most challenging conditions.
