The FAG NU304-E-XL-M1A-C3 is a high-performance single-row cylindrical roller bearing, part of the FAG X-Life series. With an inner diameter of 20mm, an outer diameter of 52mm, and a width of 15mm, this bearing is designed for robust applications. It features a separable design, allowing the inner ring to be removed from the outer ring assembly for easier mounting. The bearing incorporates a solid brass cage that is roller guided (M1A) and provides C3 radial internal clearance, which is greater than normal, making it suitable for conditions with higher operating temperatures or shaft expansion. The 'E' designation indicates an optimized internal design for enhanced load carrying capacity, while 'XL' signifies X-Life quality, ensuring improved performance and extended service life.
