| Deep groove ball bearing with seals or shields | |||||||||
Deep groove ball bearing with seals or shields Single row deep groove ball bearings with seals or shields are particularly versatile, have low friction and are optimized for low noise and low vibration, which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than many other bearing types. The integral sealing can significantly prolong bearing service life because it keeps lubricant in the bearings and contaminants out. Integral sealing prolongs bearing service life, simple, versatile, robust design low friction, high-speed makes radial and axial load in both directions, so it requires little maintenance. |

The SKF 61888 is another type of deep groove ball bearing, but with different dimensions and specifications compared to the 61880. Key Specifications: Type: Deep groove ball bearing Inner Diameter (d): 440 mm Outer Diameter (D): 540 mm Width (B): 46 mm Dynamic Load Rating (C): Approximately 1350 kN (varies depending on specific variant) Static Load Rating (C0): Approximately 1460 kN (varies depending on specific variant) Limiting Speed: High, depending on lubrication and specific operating conditions. Material: Typically made from high-quality chrome steel (GCr15) for longevity and resistance to wear, although variations may include stainless steel or ceramic balls for specific environments. Lubrication: Lubrication options may include grease or oil, and the bearing may come in different versions (e.g., open, sealed, or shielded). Features: High Load Capacity: The SKF 61888 has a larger size and correspondingly higher load ratings compared to the 61880, making it suitable for applications requiring heavy-duty performance. Versatility in Applications: Like other deep groove ball bearings, it can support both radial and axial loads in both directions, making it a versatile option for a variety of machines. Smooth Operation: Designed to operate with minimal noise and vibration, which is important for high-speed or precision machinery. Low Maintenance: With proper lubrication, these bearings can offer long service intervals, reducing the need for frequent maintenance. Different Sealing Options: Depending on the environmental conditions of the application, the bearing may come with shields (Z or 2Z) or seals (RS or 2RS) to protect against contamination. Common Applications: Heavy Machinery: In industries like steel production, mining, and large machines where high load capacity is essential. Electric Motors: Especially larger motors that require bearings with high dynamic load capacity. Generators: Bearings used in industrial power generation often require deep groove ball bearings of this size and load rating. Conveyors and Crushers: For applications that involve heavy loads or high speeds. Key Considerations: Speed Limitations: The maximum speed of the bearing can vary based on its size, lubrication type, and environmental conditions, so ensuring the right lubrication and installation conditions are critical for optimal performance. Temperature Range: Depending on the material and lubrication type, the bearing can typically operate within a range of -30°C to +120°C, though specialized versions for higher or lower temperatures may be available. | |||||||||
