33218

The 33218 Tapered Roller Bearing is an essential component engineered for high-performance applications that demand superior load-carrying capability. This single-row metric bearing is designed with conical rollers and raceways, a geometry that expertly manages both high radial loads and substantial single-direction axial (thrust) loads simultaneously. Its separable design, consisting of the cone (inner ring assembly with rollers) and the cup (outer ring), allows for straightforward mounting and adjustment. Key specifications for the 33218 include a 90 mm bore diameter, a 160 mm outside diameter, and a total width of 55 mm. This bearing is commonly manufactured from hardened steel for exceptional durability and is frequently employed in demanding industrial sectors such as mining, heavy machinery, automotive wheel assemblies, and steel manufacturing, ensuring reliable operation and extended service life even under challenging conditions.

The 33218 bearing adheres to international standards (e.g., DIN ISO 355 / DIN 720), making it reliably interchangeable across major bearing brands, which simplifies procurement and replacement. Its precision manufacturing, often to tolerance classes like P0 or P6X, minimizes friction, noise, and heat generation, which contributes to improved operational efficiency and reduced energy consumption. The robust steel cage (often stamped or window-type, roller-guided) ensures accurate roller spacing and guidance. Selecting the correct lubrication (grease or oil) and proper setting of the bearing clearance during installation are crucial for maximizing the 33218's dynamic load rating (approx. 350 kN to 415 kN) and achieving its full limiting speed potential (up to 4000 r/min). Trust the proven design of the 33218 to deliver stability and endurance in your critical rotating equipment.
