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:
