EspañolSF-2Y composite bearings are oil-free bearings, and their inner and outer layers are made of a series of carefully designed composite materials. These bearings are often used in environments where long-term efficient operation is required and regular lubrication is not possible, and are commonly found in the automotive, industrial machinery, wind power generation, aerospace and other fields. Its "oil-free lubrication" feature makes it an environmentally friendly choice, reducing the use of traditional grease and avoiding the potential risk of lubricant leakage.
Specifications and tolerance requirements for SF-2Y composite bearings
Material and structural design: SF-2Y composite bearings are usually composed of three layers of materials: the inner layer is a metal substrate, the middle layer is a reinforcing material (such as glass fiber, carbon fiber, etc.), and the outer layer is a wear-resistant layer (usually using special self-lubricating materials). This structure can provide excellent friction performance and wear resistance while ensuring mechanical strength.
Bearing size specifications: The size and specifications of SF-2Y composite bearings can be customized according to customer needs, but usually the inner and outer diameters of the bearings are very wide, suitable for different types of mechanical equipment. Standard specifications typically cover sizes ranging from a few millimeters to hundreds of millimeters to meet the needs of different industries.
Tolerance requirements: Tolerance control is a critical part of the production process of SF-2Y composite bearings. The tolerances of the inner diameter, outer diameter and thickness of the bearing must meet strict standards to ensure its stability under high load and high speed operation. The specific tolerance requirements vary depending on the application, but high-precision dimensions and surface finish are generally required to reduce friction and wear.
Performance standards: SF-2Y composite bearings need to meet certain performance requirements, including:
Temperature resistance: SF-2Y bearings can operate under extreme temperature conditions and can withstand high temperatures of more than 250°C.
Corrosion resistance: Composite materials have excellent corrosion resistance and can adapt to various harsh environments.
Load capacity: SF-2Y bearings have a high load-bearing capacity and are suitable for high-load working environments.
Self-lubricating properties: One of the biggest advantages of SF-2Y composite bearings is their self-lubricating properties. Without the need for external lubricants, the lubricating components in the bearing material can be automatically released during operation, significantly reducing the coefficient of friction and extending service life. This feature is especially important for special applications such as high temperatures or hard-to-reach areas.
