62303-2RS1/C3 Bearing Product Overview & Core Advantages
The 62303-2RS1/C3 is a single row deep groove ball bearing designed for exceptional performance in demanding applications. This sealed metric bearing excels at handling primarily radial loads while also accommodating moderate axial loads in both directions. Its compact design, featuring a 17 mm bore and 47 mm outside diameter, makes it ideal for applications where space is at a premium. Manufactured to ABEC 1 | ISO P0 tolerance standards, it delivers reliable and consistent operation, ensuring high precision and long service life in a wide range of industrial machinery.
62303-2RS1/C3 Bearing Model Code Explained, Specifications & Naming Convention
The model number 62303-2RS1/C3 provides detailed technical specifications:
- 62303: Basic designation for a single row deep groove ball bearing with a 17 mm bore and 47 mm OD.
- 2RS1: Indicates the bearing is equipped with two rubber contact seals (RS1), one on each side. These seals provide superior protection against contaminants and retain lubricant effectively.
- C3: Specifies a greater radial internal clearance than the standard C0 group. This is beneficial for applications with higher operational temperatures or where fits result in a reduction of internal clearance.
62303-2RS1/C3 Bearing Structural Features & Performance Benefits
The 62303-2RS1/C3 is engineered for durability and performance. Its single row deep groove raceway is precision-ground from high-quality chrome steel, providing a robust path for the chrome steel balls. The integral steel cage ensures proper ball spacing and guidance, contributing to smooth, low-vibration operation at its limiting speed of 11,000 rpm. The 2RS1 rubber contact seals are a critical feature, offering excellent exclusion of moisture and dirt while retaining any future-applied lubricant, making the bearing suitable for environments where contamination is a concern. The C3 radial internal clearance allows for thermal expansion, making it a reliable choice for applications with significant temperature variations.
62303-2RS1/C3 Bearing Typical Application Areas
This versatile bearing is commonly specified in a variety of sectors due to its robust construction and sealed design. Key applications include:
- Electric Motors and small gearboxes.
- Industrial Pumps and compressors.
- Agricultural machinery and conveyor systems.
- Material handling equipment and power tools.
- Automotive components such as alternators and idler pulleys.
