Whether used in maintenance, upgrades, or custom assemblies, SKF components ensure reliability and efficiency in even the most demanding environments.
The main components of SKF bearings include inner and outer rings, rolling elements, gaskets, mounting holes, seals, loading plugs, gears, and grease filling ports. These components together form the complete structure of SKF bearings, ensuring their excellent performance in various applications.
Inner and outer rings: The inner and outer rings are the main components of SKF bearings, made of carbon steel material and featuring precision raceways. They are responsible for transmitting loads and relative motion, and withstand high stress through hardening treatment
Rolling elements: Rolling elements include balls and rollers, usually made of hardened chromium alloy steel material. These components rotate between the inner and outer rings, transmitting loads and providing uniform load distribution, reducing rotational resistance
Gasket: Gaskets are used to separate rolling elements, reducing friction, slippage, and jamming. Usually made of plastic materials compatible with lubricants and operating environments
Installation hole: Installation holes are used for assembly and maintenance, usually threaded holes designed as evenly spaced through holes for easy bolt connections
Sealing element: The sealing element is located on both sides of the bearing, retaining lubricant and preventing dust and small particles from entering the bearing. It is made of elastic material and compatible with most common lubricants
Loading plug: Loading plugs are used to fix the position of rolling elements to ensure correct orientation. Some models, such as the TR series, do not have loading plugs and require the assembly of rolling elements by separating the rings
Gears: Some SKF bearings are equipped with gear teeth, usually full depth or short involute spur gears, providing backlash and complying with AGMA Q6 quality standards
Lubricating grease filling port: The bearing ring is equipped with a lubricating grease filling port, which is used to regularly add lubricating grease to maintain the good operating condition of the bearing
