6311-2RS1/C3 Bearing Product Overview & Core Advantages
The 6311-2RS1/C3 is a metric single row deep groove ball bearing engineered for robust performance and long service life. Its primary advantage lies in its ability to efficiently handle radial loads while offering reliable operation across a wide temperature range. The bearing features integrated seals (2RS1) for superior contamination protection and a greater than normal radial internal clearance (C3), making it exceptionally suitable for applications involving thermal expansion or where fits result in a reduction of internal clearance. This combination delivers a durable, maintenance-free solution for a broad spectrum of industrial machinery.
6311-2RS1/C3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 6311 | Basic bearing designation indicating a single row deep groove ball bearing with a 55 mm bore, 120 mm OD, and 29 mm width. |
| 2RS1 | Signifies contact seals on both sides of the bearing. These rubber seals provide excellent protection against contaminants and retain lubricant effectively. |
| C3 | Indicates a greater than normal radial internal clearance. This is critical for applications with thermal expansion or where interference fits are used, preventing premature failure due to excessive preload. |
6311-2RS1/C3 Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured from chrome steel for rings, balls, and cage, this bearing offers high strength and durability. With a dynamic load rating of 16,096 lbf and a static load rating of 10,116 lbf, it is built to withstand significant radial stresses.
- Enhanced Sealing for Contaminated Environments: The 2RS1 double-contact seals create an effective barrier against dust, moisture, and other particulate matter, significantly extending bearing life in harsh conditions and making it a maintenance-free component.
- Optimized Internal Clearance for Demanding Applications: The C3 clearance group ensures reliable performance in scenarios where shaft or housing fits, or operational heat, could otherwise lead to binding and increased friction.
- Standard Precision & Speed Capability: Conforming to ABEC 1 | ISO P0 tolerance class, it provides reliable performance for most general industrial applications, with a limiting speed of 5,600 rpm.
