6306-2RS1/C3LT20 Bearing Product Overview & Core Advantages
The 6306-2RS1/C3 is a single row deep groove ball bearing designed for robust performance in demanding applications. Its primary strength lies in its ability to efficiently handle radial loads while also accommodating moderate axial loads in both directions. The bearing features integral contact seals (2RS1) for superior contamination protection and is supplied with a C3 radial internal clearance, making it suitable for applications with thermal expansion or where interference fits are used. This combination delivers a compact, reliable, and maintenance-free solution for a wide range of industrial machinery.
6306-2RS1/C3LT20 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning | Significance |
|---|---|---|
| 6306 | Basic Bearing Series & Size | Denotes a medium-duty, single row deep groove ball bearing with a 30mm bore, 72mm OD, and 19mm width. |
| 2RS1 | Seal Type | Indicates the bearing is fitted with rubber contact seals on both sides. This provides excellent protection against dust and moisture ingress, retaining lubricant for long service life. |
| C3 | Radial Internal Clearance | Specifies a greater than normal radial internal clearance. This is advantageous in applications with high operational temperatures or heavy interference fits, preventing premature failure due to thermal expansion. |
6306-2RS1/C3LT20 Bearing Structural Features & Performance Benefits
Sealed for Reliability: The 2RS1 rubber contact seals are a key structural feature, providing a highly effective barrier against contaminants. This design significantly extends bearing life in dirty or humid environments and makes the unit pre-lubricated and maintenance-free for its entire service life.
Optimized Internal Geometry: As a standard deep groove ball bearing, its raceways are precisely machined to facilitate smooth rolling motion and low torque, contributing to high limiting speeds of up to 9,600 rpm.
Robust Load Capacity: Manufactured from chrome steel for both rings and balls, the bearing offers a high dynamic load rating of 6002 lbf and a static load rating of 3372 lbf, ensuring durability under significant radial loads.
Wide Operating Range: With a specified operating temperature range from -30°C to 120°C, this bearing is suitable for use in a variety of climatic and operational conditions.
6306-2RS1/C3LT20 Bearing Typical Application Areas
