30240

The 30240 is a single-row metric tapered roller bearing designed for robust performance in applications demanding high load resistance. This bearing utilizes a geometric principle where the rollers and raceways are tapered, allowing it to efficiently manage combined radial and heavy single-direction axial loads. Its separable design, consisting of a cone assembly (inner ring with rollers and cage) and a cup (outer ring), offers a major practical advantage, simplifying the complexities of both mounting and regular maintenance procedures. This feature is particularly valued in high-torque industrial transmissions and heavy vehicle axles where downtime minimization is critical.

Measuring 200 mm for the bore diameter and 360 mm for the outside diameter, with a substantial total width of 64 mm, the 30240 is a large-format bearing built for durability. The precision ground rollers and raceway surfaces are engineered to promote an optimal lubricant film, which significantly contributes to reduced friction and operating temperatures, thereby extending the bearing's service life. When paired correctly with a second opposing tapered roller bearing, the 30240 can be adjusted to achieve a specific operating clearance or preload, providing the stiffness necessary for accurate shaft guidance in harsh environments such as large construction machinery, mining equipment, and high-capacity industrial gearboxes.
