6302-2RSH/C3 Bearing Product Overview & Core Advantages
The 6302-2RSH/C3 is a metric single row deep groove ball bearing designed for robust performance in demanding applications. Its core advantages stem from its sealed design (2RSH) and optimized internal geometry, providing reliable operation and long service life. This bearing excels at handling primarily radial loads and is characterized by its high limiting speed and increased radial internal clearance (C3), making it suitable for applications with thermal expansion considerations. Manufactured to ABEC 1 | ISO P0 tolerance standards, it offers a dependable balance of precision and cost-effectiveness for a wide range of industrial uses.
6302-2RSH/C3 Bearing Model Code Explained, Specifications & Naming Convention
- 6302: Basic series code indicating a medium-duty, metric deep groove ball bearing with a 15mm bore, 42mm OD, and 13mm width.
- 2RSH: Designates contact seals on both sides. The "H" suffix often indicates a high-performance sealing material (e.g., NBR rubber), offering superior protection against contaminants and improved grease retention compared to standard seals.
- C3: Specifies a greater radial internal clearance than the standard C0 group. This is advantageous in applications where thermal expansion of the shaft or housing is expected, preventing preload and potential bearing failure.
6302-2RSH/C3 Bearing Structural Features & Performance Benefits
Sealed & Protected Design: The double-sided contact seals (2RSH) effectively shield the bearing's internals from dust, moisture, and other contaminants, while also retaining the factory-applied lubricant. This results in enhanced reliability and reduced maintenance requirements.
Optimized Load Capacity: The deep groove raceway and high-quality chrome steel construction enable the bearing to carry significant radial dynamic (2563 lbf) and static (1225 lbf) loads, ensuring stable operation under various conditions.
High-Speed Capability: The precision-ground components and efficient design contribute to a high limiting speed of 17,000 rpm, making it suitable for electric motors, spindles, and other high-speed machinery.
Thermal Stability: The C3 clearance provides operational stability across a broad temperature range (-30°C to 120°C), accommodating thermal expansion without compromising performance.
6302-2RSH/C3 Bearing Typical Application Areas
The 6302-2RSH/C3 is widely used in industries and equipment requiring reliable, sealed bearings for high-speed operation. Common applications include:
- Electric Motors and Small Gearboxes
- Industrial Pumps and Compressors
- Material Handling Equipment
