We supply standard grades from G5 to G100, with higher grades (e.g., G5, G10) offering the tightest tolerances for critical, high-speed applications. Sizes are available in a wide range, from miniature sizes of 0.5mm (0.0197") to larger diameters of 50.8mm (2.0") and beyond, depending on the material. Materials & Key Properties: • Chrome Steel : The industry standard, offering an excellent balance of hardness (60-67 HRC) and load capacity. Ideal for most general industrial and automotive applications. • Stainless Steel (440C, 316): Provides superior corrosion resistance. Grade 440C is martensitic and can be hardened to 58-60 HRC, suitable for food, marine, and chemical environments. Grade 316 (austenitic) offers maximum corrosion resistance for highly aggressive media. • Ceramic (ZrO2/Si3N4): These advanced bearing balls are lightweight (60% lighter than steel), electrically insulating, and highly resistant to wear, corrosion, and thermal expansion. They operate effectively in high-speed, high-temperature, and chemically hostile environments where metal fails.

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 N, NU, NJ, NUP, and NF, each designed for specific internal configurations and axial displacement capabilities (e.g., NU design allows free axial displacement of the shaft).
Bore Diameter Range: From 20 mm to over 300 mm, catering to a vast spectrum of industrial machinery.
Precision Classes: Available from standard ABEC 1 (P0) to high-precision 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.
Internal Clearance: Supplied with standard radial internal clearance (C0, CN), with modified clearance groups (C3, C4) available for applications with specific thermal expansion or fit requirements.
