Deep groove ball bearing SKF 6309-2RS1NR, Outer diameter: 100 mm | Width: 25 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 deep groove ball bearing guarantees reliable performance in demanding industrial environments, combining durability with enhanced protection against contaminants thanks to its NBR rubber seals. Equipped with an integrated stop ring in the outer ring groove, this model ensures a secure axial fit, allowing for optimal positioning in applications requiring high precision.

Features:
This SKF single-row deep groove ball bearing, featuring standard radial clearance (CN), withstands high radial loads and moderate axial loads. Its integrated stop ring in the outer ring enhances axial stability and reduces the risk of misalignment. Its sheet steel cage ensures increased robustness, capable of withstanding shocks and load variations. This bearing also allows for high speeds while minimizing friction levels for smooth and quiet operation. Its rubber seals on both sides provide effective protection against contaminants such as dust, water, and oils, while keeping the lubricant inside to extend its service life.

Maintenance:
Thanks to its rubber seals, this bearing is protected from contaminants and the lubricant is effectively retained inside, which significantly reduces maintenance requirements. Although these seals may add slight friction resistance, they extend the bearing’s service life by maintaining optimal cleanliness. However, it is recommended to periodically check temperature, vibration, and noise levels, especially during heavy-duty use. These checks help detect any signs of wear and maintain optimal performance.

Sealing:
Its nitrile-butadiene rubber (NBR) seals on both sides create a reliable barrier that prevents contaminants (dust, water, oils) from penetrating—which is essential in damp or dusty environments—while also keeping the lubricant inside.

Brand Information:
SKF, founded in 1907, is a leading provider of solutions for rotating equipment. Specializing in bearings, seals, and lubrication systems, the Swedish brand is recognized for its technical expertise and innovations that meet the diverse needs of industrial sectors such as automotive, aerospace, energy, and food processing.

Key Features:
- Reliable protection against dust, water, and oils thanks to rubber seals;
- Resistance to high radial loads and moderate axial loads;
- Quiet and smooth operation, even at high speeds;
- Sturdy and durable sheet steel cage;
- Reduced maintenance requirements thanks to effective lubricant retention by the seals.

Applications:
This SKF deep groove ball bearing is particularly well-suited for industrial applications, such as conveyors, material handling equipment, and agricultural machinery. Its ability to handle high radial loads and its resistance to dusty or humid conditions make it a reliable choice for continuous production systems. It is also suitable for environments where high rotational speeds are required while maintaining moderate noise and friction levels, such as in production lines and warehouse logistics systems.
