SUPER PRECISION CYLINDRICAL ROLLER BEARINGS

Super precision cylindrical roller bearings feature higher radial rigidity and can take higher radial loads than ball bearings; this makes them especially suitable for applications that require high rigidity such as lathe spindles, and for use as rear end bearings subjected to large belt loads.

The optimized internal design and cage shape of NSK cylindrical roller bearings are the reason why they achieve low heat generation and stable operation in high-speed applications. Double-row cylindrical roller bearings are also available in“E44” specification for oil lubrication with lubrication holes and oil groove in the center of the outer ring.

Single row and double row versions available

Low heat generation

Improved seizure resistance

Stable operation in ultra high speed
