SKF (Svenska Kullagerfabriken AB) is a Swedish company and one of the world's leading manufacturers of bearings, seals, lubrication systems, and related services. Founded in 1907, SKF has built a global reputation for high-quality products and innovation in the field of rotating equipment. 1. Types of SKF Bearings SKF manufactures a wide range of bearing types, including: A. Ball Bearings These bearings use balls to maintain the separation between bearing races. Deep Groove Ball Bearings Most common type Support radial and axial loads High-speed capability Angular Contact Ball Bearings Designed to handle combined loads (radial + axial) Often used in pairs or sets Self-aligning Ball Bearings Accommodate misalignment Used in applications where shaft deflection occurs B. Roller Bearings Use cylindrical rollers instead of balls, suitable for heavy radial loads. Cylindrical Roller Bearings High radial load capacity Limited axial load capability Spherical Roller Bearings Accommodate misalignment and heavy loads Suitable for harsh environments Tapered Roller Bearings Handle large radial and axial loads Common in automotive and heavy machinery Needle Roller Bearings Small diameter rollers Compact and suitable for radial loads in limited space 2. Key Features of SKF Bearings High precision and durability Low friction and noise levels Advanced sealing technology Enhanced lubrication options Custom solutions for extreme environments 3. Applications SKF bearings are used in nearly every industry, including: Automotive (wheel hubs, engines, transmissions) Industrial Machinery (gearboxes, pumps, compressors) Aerospace (jet engines, landing gear) Railways Energy (wind turbines, hydroelectric plants) Food and Beverage (special hygienic bearings) 4. SKF Bearing Numbering System SKF bearing numbers are coded to convey important information. Example: 6205-2RS1 6205 = Type and size 2RS1 = Sealed on both sides with rubber seals Prefixes and suffixes indicate features like: Internal clearance (e.g., C3, C4) Tolerance class (e.g., P6, P5) Material and coating (e.g., VA201 for high temperature) 5. Bearing Maintenance and Services SKF also provides: Condition monitoring Lubrication systems Alignment tools Bearing remanufacturing Predictive maintenance technologies 6. Advanced Technologies SKF Explorer series: Enhanced performance bearings with improved steel and design. Sensor Bearings: Integrate sensors for speed, temperature, and vibration. Solid Oil Bearings: For extreme contamination and low maintenance needs.
