KOYO Deep Groove Ball Bearing, Inner Dia 240 mm, Outer Dia 440 mm, Width 72 mm, 6248

A KOYO 240 mm Deep Groove Ball Bearing 6248 is a popular type of rolling element bearing that is widely used in various applications. It is characterized by its deep raceway grooves, which enable it to accommodate both radial and axial loads in multiple directions. Here are some key features and characteristics of deep groove ball bearings: Construction: Deep groove ball bearings consist of an inner ring, an outer ring, a series of balls, and a cage that separates and guides the balls. The inner and outer rings have deep, uninterrupted raceway grooves that are typically circular in shape. Load Capacity: Deep groove ball bearings are primarily designed to carry radial loads, but they can also withstand limited axial loads in both directions. The load capacity depends on the size and design of the bearing and is influenced by factors such as the number and size of the balls. Low Friction: Deep groove ball bearings are known for their low frictional resistance. The smooth contact between the balls and the raceway grooves results in efficient operation and reduced energy consumption. Speed Capability: Deep groove ball bearings can operate at high speeds, although the maximum speed is influenced by factors such as the bearing size, lubrication, and operating conditions. Higher precision bearings and specialized designs are available for applications requiring extremely high speeds. Versatility: Deep groove ball bearings are versatile and suitable for a wide range of applications, including electric motors, automotive components, industrial machinery, household appliances, pumps, and more. They are commonly used in both small and large equipment. Sealing Options: Deep groove ball bearings can be equipped with various sealing options to provide protection against contamination and retain lubrication. Common sealing types include shields (metallic or non-metallic) and seals (contact or non-contact). Sealed bearings offer better protection but may have slightly higher friction. Lubrication: Proper lubrication is crucial for the performance and longevity of deep groove ball bearings. They can be lubricated with grease or oil, depending on the application requirements and operating conditions. Lubrication helps to reduce friction, dissipate heat, and prevent corrosion. Deep groove ball bearings are available in different sizes, configurations, and materials to suit specific application needs. It's important to consult bearing manufacturers or engineering references to select the appropriate bearing type and size based on factors such as load requirements, operating conditions, and environmental considerations.
