Super precision double row cylindrical roller bearings are specialized and highly precise rolling-element bearings designed for applications that require extreme accuracy, high radial load capacity, and rigidity. These double row bearings consist of two sets of cylindrical rollers arranged in parallel and separated by a central rib on the inner ring. They are used in applications where radial loads need to be supported with precision and minimal deflection, and they are particularly suitable for high-speed and high-precision machinery. Here are the key features and characteristics of super precision double row cylindrical roller bearings:

1. High Precision: These bearings are manufactured with exceptionally tight tolerances to ensure minimal deflection, which is crucial for high-precision applications.
2. Double Row Design: Double row cylindrical roller bearings consist of two rows of cylindrical rollers, which increase their radial load-carrying capacity. The rollers are guided between the integral flanges on the outer ring and the central rib on the inner ring.
3. High Radial Load Capacity: These bearings are designed to support high radial loads, making them ideal for applications with demanding load requirements.
4. High Speed Capabilities: Super precision double row cylindrical roller bearings are engineered for high-speed operation, thanks to their precision manufacturing and efficient roller design.
5. Rigidity: The construction of these bearings, including materials and design, ensures high rigidity, reducing deflection and improving performance under load.
6. Precision Lubrication: Super precision bearings are often equipped with specialized lubrication systems to further enhance their performance and extend their service life.

Super precision double row cylindrical roller bearings find application in various high-precision and high-speed applications, including:

• Machine Tools: In precision machinery like CNC machining centers, grinding machines, and milling machines, where high accuracy and rigidity are crucial.
