6005-RS1/C4MT648 Bearing Product Overview & Core Advantages
The 6005-RS1/C4MT648 is a single row deep groove ball bearing engineered for high-performance applications demanding reliability and precision. This metric bearing is characterized by its sealed design and optimized internal geometry, enabling it to handle significant radial loads efficiently. A key advantage is its pre-lubrication with a high-performance grease, combined with a generous radial internal clearance (C4), making it exceptionally suitable for applications with thermal expansion or where high operational temperatures are anticipated. Its compact design and ABEC 1 (ISO P0) tolerance ensure consistent performance in a wide range of industrial settings.
6005-RS1/C4MT648 Bearing Model Code Explained, Specifications & Naming Convention
- 6005: Basic model number indicating a single row deep groove ball bearing with a 25mm bore diameter, 47mm outside diameter, and 12mm width.
- RS1: Designates a contact seal on one side of the bearing. This seal effectively prevents the ingress of contaminants and retains the lubricant, enhancing bearing life and enabling maintenance-free operation in many environments.
- C4: Specifies a greater radial internal clearance than normal. This is crucial for applications involving thermal expansion, high-speed operation, or where shaft and housing fits result in a reduction of internal clearance.
- MT648: Indicates the bearing is pre-lubricated with a specific, high-quality polyurea grease. This grease is suitable for the specified temperature range (-30°C to 120°C) and contributes to the bearing's long service life and high-speed capability.
6005-RS1/C4MT648 Bearing Structural Features & Performance Benefits
Robust Sealed Construction: The integrated RS1 contact seal provides superior protection against dust, moisture, and other particulate contaminants. This feature is vital for maintaining lubricant integrity and preventing premature failure in challenging environments, significantly boosting operational reliability.
Optimized Load Capacity: Manufactured from high-grade chrome steel for both rings and balls, this bearing offers a high dynamic load rating of 2271 lbf and a static load rating of 1315 lbf. The deep groove raceway is precision-engineered to sustain substantial radial loads, ensuring stable performance under demanding conditions.
Enhanced Operational Flexibility: The combination of C4 clearance and pre-lubrication with MT648 grease allows for a high limiting speed of 15,000 rpm. The increased clearance accommodates thermal expansion, preventing binding and overheating at high speeds, while the specialized grease ensures smooth rotation and reduces wear.
Precision and Compliance: Built to ABEC 1 (ISO P0) tolerance class, it guarantees running accuracy for most industrial applications. The bearing is also ROHS and REACH compliant, meeting stringent international environmental and safety standards.
6005-RS1/C4MT648 Bearing Typical Application Areas
This versatile bearing is ideally suited for a broad spectrum of applications where reliability, speed, and contamination resistance are paramount. Key sectors include:
- Electric Motors and Generators: For shaft support in small to medium-sized motors requiring long-term, maintenance-free operation.
- Industrial Gearboxes and Transmissions: Providing precise and reliable rotation in power transmission systems.
- Material Handling Equipment: Such as conveyor rollers and pulleys, where sealed bearings are essential for durability.
- Agricultural Machinery: In components exposed to dust and debris, benefiting from the robust sealing.
- Automotive Auxiliary Units: Including alternators, idlers, and tensioners.
