Heavy-Duty High Load Precision NJ EM...
Our cylindrical roller bearings are suitable for transmissions, motors, machine tools and heavy industrial equipment, featuring a long service life, reduced maintenance requirements and optimized power transmission performance.
Product Design and Core Specifications
A cylindrical roller bearing is characterized by its cylindrical rolling elements with a length typically greater than their diameter. This linear contact with the raceways, as opposed to the point contact in ball bearings, is the key to its exceptional performance. We offer a comprehensive range of standard types and sizes:

- Standard Series: Includes popular series such as 氮, NU, NJ, NUP, 和 NF, each designed for specific internal configurations and axial displacement capabilities (例如, NU design allows free axial displacement of the shaft).
- Bore Diameter Range: 从 20 mm to over 300 毫米, catering to a vast spectrum of industrial machinery.
- Precision Classes: Available from standard ABEC 1 (P0) 高精度ABEC 5 (P5) for applications requiring exceptional running accuracy and minimum vibration.
- Cage Options: Standard cages include high-strength, precision-stamped steel cages for durability and speed. Machined brass or polymer cages are available for specialized high-speed or corrosive applications.
- 内部游隙: Supplied with standard radial internal clearance (二氧化碳, 中国), with modified clearance groups (C3, C4) available for applications with specific thermal expansion or fit requirements.
