6301-2RS1/VM045 Bearing Product Overview & Core Advantages
The 6301-2RS1/VM045 is a single row deep groove ball bearing designed for exceptional performance in a wide range of industrial applications. Its core advantage lies in its ability to handle significant radial loads while also accommodating moderate axial loads in both directions. The bearing features integrated seals (2RS1) and is pre-lubricated with a specialized high-performance grease (VM045), making it a robust, ready-to-install, and long-lasting solution that requires minimal maintenance. Manufactured to ABEC 1 | ISO P0 tolerance standards, it ensures reliable operation and consistent performance.
6301-2RS1/VM045 Bearing Model Code Explained, Specifications & Naming Convention
The model number 6301-2RS1/VM045 provides detailed technical specifications through its suffixes:
- 6301: Standard designation for a metric single row deep groove ball bearing with a 12mm bore, 37mm OD, and 12mm width.
- 2RS1: Indicates the bearing is equipped with contact seals on both sides. These seals provide superior protection against contamination and retain lubricant effectively.
- VM045: Specifies the type of high-performance grease used for pre-lubrication. This grease is formulated for a broad temperature range and extended service life.
6301-2RS1/VM045 Bearing Structural Features & Performance Benefits
- Robust Construction & High Load Capacity: Manufactured from chrome steel for rings, balls, and cage, this bearing offers high strength and durability. Its deep groove raceway and optimized internal geometry enable it to support a high radial dynamic load rating of 2181 lbf and a radial static load rating of 944 lbf.
- Effective Sealing & Contamination Resistance: The double-contact seals (2RS1) are a critical feature, providing an effective barrier against dust, dirt, and moisture. This makes the bearing ideal for harsh environments and contributes to its maintenance-free characteristic.
- Optimized for Versatile Applications: With a limiting speed of 20,000 rpm and a standard CN radial internal clearance, the bearing is well-suited for a variety of operational conditions. The pre-applied VM045 grease ensures immediate and reliable lubrication from startup.
6301-2RS1/VM045 Bearing Typical Application Areas
This versatile bearing is commonly specified in:
- Electric Motors and Generators
- Gearboxes and Transmission Systems
- Industrial Fans and Blowers
- Material Handling Equipment (e.g., conveyor rollers)
- Agricultural Machinery
- Automotive Components (e.g., alternators, water pumps)
