6224 MA/C3B20 Bearing Product Overview & Core Advantages
The 6224 MA/C3B20 is a single row deep groove ball bearing designed for robust performance in demanding industrial applications. This metric bearing features an open design and is engineered to primarily handle radial loads with high efficiency. Its key advantages include a high radial dynamic load rating of 32,822 lbf and a radial static load rating of 26,527 lbf, ensuring reliable operation under significant stress. Manufactured from high-grade chrome steel with a machined metal cage, it offers excellent durability and stability. The bearing's C3 radial internal clearance makes it particularly suitable for applications where thermal expansion is a factor, providing operational reliability across a wide temperature range of -30°C to 120°C.
6224 MA/C3B20 Bearing Model Code Explained, Specifications & Naming Convention
- 6224: Basic bearing designation indicating a metric deep groove ball bearing with a 120mm bore, 215mm OD, and 40mm width.
- M: Denotes a machined brass cage, offering superior strength and guidance at higher speeds compared to stamped cages.
- A: Indicates an optimized internal design for enhanced load capacity and performance.
- /C3: Specifies a greater than normal radial internal clearance. This is crucial for applications with high thermal gradients or where fits result in a reduction of clearance, preventing seizure.
- B20: A manufacturer-specific suffix often indicating specific heat stabilization treatment for consistent performance up to 120°C, ensuring dimensional stability.
6224 MA/C3B20 Bearing Structural Features & Performance Benefits
The single row deep groove ball bearing construction of the 6224 MA/C3B20 is a hallmark of versatility and reliability. The deep, continuous raceways on both rings enable it to handle not only radial loads but also moderate axial loads in both directions. The use of a machined metal cage (MA) significantly contributes to the bearing's high limiting speed of 5,600 rpm, providing excellent guidance and stability for the balls, reducing friction and wear. The C3 clearance is a critical feature that accommodates shaft expansions or misalignments, making the bearing exceptionally robust in applications with varying operational temperatures. Manufactured to ABEC 1 | ISO P0 tolerance class, it ensures consistent and precise operation for a wide range of industrial machinery.
6224 MA/C3B20 Bearing Typical Application Areas
The 6224 MA/C3B20 is ideally suited for a variety of heavy-duty and general industrial applications where high radial load capacity and reliability are paramount. Its robust construction makes it a preferred choice for:
- Electric Motors and Generators: Providing stable support for rotors under high rotational speeds.
- Gearboxes and Transmissions: Handling significant radial forces in power transmission systems.
- Industrial Pumps and Compressors: Offering reliable performance in fluid handling equipment.
- Material Handling Equipment: Such as conveyor pulleys and rollers, where consistent bearing performance is critical.
- Agricultural and Construction Machinery: Withstanding harsh operating conditions and shock loads.
