6208E Is A Deep Groove Ball Bearing For Industrial And Household Appliances
1. Basic Type of the Product
Deep groove ball bearings are representative rolling bearings with a wide range of applications. They are suitable for operation at high rotational speeds, even extremely high rotational speeds, and are highly durable, requiring little frequent maintenance. This type of bearing features a low friction coefficient, high limiting speed, simple structure, low manufacturing cost, and ease of achieving high manufacturing precision. With a wide range of sizes and diverse configurations, they are used in industries such as precision instruments, low-noise motors, automobiles, motorcycles, and general machinery, making them the most widely used type of bearings in the machinery industry. They mainly bear radial loads and can also withstand a certain amount of axial loads.
2. Core Specification Parameters
Item
Parameter
Description
Bore Diameter (d )
40 mm
Matches the shaft diameter.
Outer Diameter (D )
80 mm
Dimension for installation space.
Width (B )
18 mm
Thickness of the bearing.
Weight
Approx. 0.37–0.38 kg

Dynamic Load Rating (Cr)
Approx. 31.3 kN
Capacity to withstand radial dynamic loads.
Static Load Rating (Cor)
Approx. 18.6 kN
Load - bearing capacity under static or low - speed conditions.
3. Performance and Structural Advantages
3.1 Load and Speed Performance
It primarily bears radial loads, while also accommodating a certain degree of axial load (when radial clearance increases, axial load - bearing capacity improves, similar to the characteristics of angular contact ball bearings).
It excels in high - speed applications: With a limiting speed of 6,600 r/min for grease lubrication, it meets the high - speed operation requirements of motors, reducers, and other equipment.
3.2 Self - Aligning and Compensation Capability
A slight tilt (≤ 8′–16′, depending on clearance) between the inner and outer rings is allowed, compensating for installation errors and enhancing stability in complex working conditions.
3.3 Material and Manufacturing Process
It uses high - carbon chromium bearing steel (GCr15, fully quenched), which undergoes precision heat treatment and machining. This ensures excellent wear resistance and fatigue resistance, guaranteeing a long service life.
4. Application Fields
Thanks to its features of "high speed, low noise, and adaptability to multiple scenarios", the 6208E is utilized across numerous industries:
General Machinery: Core transmission components such as motors, reducers, belt conveyors, idlers, and hoists.
Transportation Equipment: Transmission systems of automobiles and motorcycles.
Livelihood and Industrial Sectors: Medical devices, agricultural machinery, office equipment (e.g., fans), household appliances (e.g., water pumps), and power tools.
