Y-bearings with a groove are typically used in applications where the rotation direction is fixed and maintenance is inconvenient. On one side of the inner ring, there is a partial groove extension that works in conjunction with a locking ring. The inner ring extension moves along the direction of rotation, allowing the locking ring to secure the collar and bearing to the shaft. A flat-head (fixed) screw is then used to further tighten the collar to the shaft for a more stable fit.
SKF offers two main series of Y-bearings:
- **YET2 Series**: This type features an extended inner ring on one side, designed to secure Superagriseal seals on both sides. The locking ring is coated with a galvanized layer, and the outer ring has two smooth holes.
- **YEL2 Series**: In this series, the inner ring extends on both sides, helping to reduce misalignment between the inner ring and the shaft, resulting in smoother operation. These bearings come with a standard Superagriseal seal and two types of oil-retaining rings:
- General steel sheet oil-retaining ring, designated as **2F**.
- Steel slinger with a rubber sealing lip (multi-seal), designated as **2RF**.
The outer ring is also designed with two smooth holes. SKF can also provide bearings without oil holes upon request, indicated by the suffix **W**. These bearings are available in metric sizes for shaft diameters ranging from 15 to 60 mm, and in inch sizes for diameters from ½ to 2 15/16 inches.

LED aluminum profiles are aluminum profiles with specific shapes made of aluminum alloy materials, which are usually used to manufacture the shell, radiator, and frame lamp parts of LED lamps. It has excellent heat dissipation function, aluminum itself has good thermal conductivity, can quickly conduct the heat energy of the LED chip, effectively reduce the temperature inside the lamp, to ensure the stable operation of the LED lamp and extend the service life. Secondly, it also has the advantages of corrosion resistance, environmental protection, recyclable and beautiful! LED aluminum surface treatment - anodizing, powder spraying, electrophoresis, fluorocarbon and other surface treatment methods. In short, LED aluminum profiles, as an important part of the field of LED lighting, play a key role in ensuring the performance and quality of lamps. With the continuous development of technology and the continuous expansion of application fields, LED aluminum profiles will continue to innovate and improve, bringing people a more high-quality, efficient and energy-saving lighting experience.
