SKF 6305-2RS1 Deep Groove Ball Bearing

Overview:

SKF 6305-2RS1 is a single-row deep groove ball bearing with contact seals (suffix 2RS1 indicates nitrile rubber seals on both sides). 6305-2RS1 is the most widely used rolling bearing type. The “2RS1” sealing design allows the bearing to be pre-filled with high-quality grease before delivery, making the product a “lubricated-for-life” type that requires no additional grease after installation.

The 6305-2RS1 bearing can simultaneously carry bidirectional radial loads and bidirectional axial loads. The built-in integrated sealing structure effectively prevents contamination ingress and avoids grease loss, significantly extending the service life. Special inner and outer diameter specifications can also be customized according to requirements to modify shafts and bearing housings.

Key Features and Advantages：

Composite Load Capacity: SKF 6305-2RS1 can withstand radial loads while simultaneously bearing slight bidirectional axial loads.

High-Speed and Low-Noise Operation: SKF 6305-2RS1 has a low friction coefficient and optimized internal geometry, resulting in low operating vibration and low noise, supporting higher operating speeds.

Integrated Double-Sided Seal (2RS1): SKF 6305-2RS1 features contact-type rubber seals, preventing grease leakage and blocking contaminants such as dust and moisture from entering the bearing interior.

Maintenance-Free: SKF 6305-2RS1 is pre-filled with grease before delivery and requires almost no additional lubrication during long-term operation under normal operating conditions.
