305608 B Bearing Product Overview & Core Advantages
The 305608 B is a metric double row angular contact ball bearing engineered for applications requiring high rigidity and precise operation under combined radial and axial loads. Its double row design provides superior stability and load-carrying capacity compared to single row bearings, making it an ideal choice for precision machinery and demanding industrial equipment. Manufactured to P6 (ABEC-3) tolerance class, it ensures consistent performance and reliability in high-speed and high-precision environments.
305608 B Bearing Model Code Explained, Specifications & Naming Convention
The model number 305608 B can be broken down as follows to understand its technical specifications:
- 305608: Basic bearing designation indicating the double row angular contact design with a 160mm bore.
- B: Denotes a specific internal design and contact angle optimized for handling significant axial loads from both directions.
- Open Seal Type: Designed for environments where external sealing is managed separately, allowing for custom lubrication solutions.
- P6 Tolerance Class: Corresponds to ABEC-3, indicating high precision dimensions and running accuracy.
- Pre-lubricated: Comes with initial lubrication suitable for the specified operating range.
305608 B Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row construction significantly increases the bearing's radial and axial stiffness, enabling it to handle combined loads effectively. With a radial dynamic load rating of 30,375 lbf and a static load rating of 49,500 lbf, it is built for demanding applications.
- Optimized for Precision: The stainless steel cage ensures smooth operation and stability at high speeds, contributing to the bearing's limiting speed of 3,000 rpm. The precise P6 tolerance guarantees minimal runout and vibration.
- Robust Material Construction: Made from chrome steel for both rings and balls, the bearing offers excellent wear resistance and durability. The specified shoulder diameters (outer: 203.1mm, inner: 181mm) ensure secure mounting and optimal load support.
- Wide Operating Range: Suitable for a temperature range from -30°C to 110°C, making it versatile for various industrial environments.
305608 B Bearing Typical Application Areas
The 305608 B double row angular contact ball bearing is commonly specified in applications requiring high precision and rigidity, such as:
- Machine Tool Spindles
- Industrial Gearboxes
- Precision Pumps and Compressors
- Material Handling Equipment
- Agricultural and Construction Machinery
