The NTN 22218EAW33ZZC3 is a genuine SNR spherical roller bearing designed for heavy-duty applications. This robust bearing features a 90mm bore, 160mm outer diameter, and 40mm width. It is equipped with W33 lubrication features (annular groove and three lubrication holes in the outer ring) for efficient grease distribution and C3 internal clearance, which is greater than normal, allowing for thermal expansion and misalignment. The 'ZZ' designation indicates that it is fitted with two metal shields, providing protection against contaminants while retaining lubricant. Ideal for machinery requiring high load capacity and self-aligning capabilities.
