6303-2RSH/W64F Bearing Product Overview & Core Advantages
The 6303-2RSH/W64F is a sealed single row deep groove ball bearing engineered for superior performance in demanding applications. This metric bearing is characterized by its ability to handle significant radial loads and moderate axial loads in both directions. Its sealed construction and Soild Oil lubrication provide a maintenance-free, long-service-life solution, making it ideal for applications requiring high reliability and minimal upkeep. Manufactured to ABEC 1 | ISO P0 tolerance standards, it ensures consistent and dependable operation.
6303-2RSH/W64F Bearing Model Code Explained, Specifications & Naming Convention
The model number 6303-2RSH/W64F provides detailed technical specifications through its suffixes:
- 63: Series designation indicating a medium duty, single row deep groove ball bearing.
- 03: Bore diameter code, corresponding to a 17 mm bore.
- 2RSH: Signifies two (2) contact seals (RS) made from Nitrile Rubber (H), offering excellent protection against contaminants and effective grease retention.
- W64: Indicates the bearing is pre-lubricated with Soild Oil, a polymer-based lubricant.
- F: Designates a CN group radial internal clearance as standard.
6303-2RSH/W64F Bearing Structural Features & Performance Benefits
- Robust Sealing & Lubrication: The 2RSH contact seals effectively shield the bearing interior from dust, moisture, and other contaminants while retaining lubricant. Combined with the integrated Soild Oil, this creates a maintenance-free system with a wide operating temperature range (-30° to 120 °C).
- High Load Capacity: Constructed from high-grade chrome steel for both rings and balls, this bearing offers a high dynamic load rating of 3057 lbf and a static load rating of 1495 lbf, ensuring durability under substantial radial stresses.
- Precision & Stability: Manufactured to ABEC 1 (ISO P0) tolerance class with a standard CN clearance, it provides reliable running accuracy and smooth operation, minimizing vibration and noise.
- Compact & Lightweight Design: With dimensions of 17x47x14 mm and a weight of only 115 g, it is an efficient and space-saving component for modern machinery.
