30218

The 30218 tapered roller bearing is a robust metric-sized unit designed for heavy-duty applications requiring high radial and axial load synchronization. With a 90mm bore, 160mm outside diameter, and a 32.5mm total width, this bearing utilizes its specialized internal geometry to manage thrust in one direction effectively. Unlike standard ball bearings, the 30218 features a separable design where the inner ring (cone) and outer ring (cup) can be mounted independently. This flexibility simplifies installation and maintenance, especially in complex mechanical setups like automotive transmissions or industrial gearboxes where precision alignment is non-negotiable.

Durability remains the core advantage of the 30218 series. Engineered from high-grade chrome steel, these bearings are built to withstand harsh environments while maintaining low friction and minimal heat generation. The tapered rollers ensure that stress is distributed evenly across the raceways, significantly extending the service life even under high-speed operations. Whether you are replacing components in a heavy-duty axle or upgrading mining machinery, the 30218 offers the mechanical stability and high static load rating (often exceeding 240kN depending on the manufacturer) needed to prevent premature equipment failure.
