6003-2RSH/C3GJN Bearing Product Overview & Core Advantages
The 6003-2RSH/C3GJN is a single row deep groove ball bearing designed for reliable performance in demanding applications. This sealed bearing excels at handling primarily radial loads and offers robust operation within a wide temperature range. Its key advantages include a C3 radial internal clearance for thermal expansion management, a high-quality chrome steel construction for durability, and integrated seals for contaminant protection, making it a versatile and dependable choice for various industrial machinery.
6003-2RSH/C3GJN Bearing Model Code Explained, Specifications & Naming Convention
- 6003: Basic model number denoting a metric, single row deep groove ball bearing with a 17mm bore, 35mm OD, and 10mm width.
- 2RSH: Signifies that the bearing is fitted with two-sided contact seals (RSH type) made of NBR rubber, providing effective protection against contaminants and retaining lubricant.
- C3: Indicates a greater than normal radial internal clearance. This is beneficial for applications with high operating temperatures or where fits result in a reduction of internal clearance.
- GJN: Specifies the use of a high-temperature, lithium soap complex grease with polyurea thickener, suitable for the bearing's specified temperature range of -30°C to 120°C.
6003-2RSH/C3GJN Bearing Structural Features & Performance Benefits
Robust Construction: Manufactured from high-grade chrome steel for both rings and balls, this bearing ensures high strength and resistance to wear, contributing to a long operational life.
Effective Sealing: The 2RSH contact seals provide superior protection against dust, dirt, and moisture. This design also effectively retains the pre-applied GJN grease, leading to a maintenance-free service life in many applications.
Optimized Internal Clearance: The C3 clearance allows for dimensional changes due to thermal expansion in the shaft and housing, preventing pre-load and potential bearing failure, making it suitable for applications with significant temperature variations.
High-Speed Capability: With a limiting speed of 21,000 rpm, the bearing is capable of supporting high rotational speeds, a characteristic enhanced by the low-friction seal design and stable cage.
6003-2RSH/C3GJN Bearing Typical Application Areas
The 6003-2RSH/C3GJN is ideally suited for a wide range of applications across various industries, including:
- Electric Motors and small Gearboxes
- Pumps and Compressors
- Agricultural Machinery
- Material Handling Equipment (e.g., conveyor rollers)
- Automotive Auxiliary Units (e.g., alternators, idlers)
