33113

The 33113 single row tapered roller bearing is a heavy-duty metric component engineered to manage intense combined radial and axial loads. With a 65mm bore, 110mm outside diameter, and a total width of 34mm, this bearing features a separable design where the inner ring (cone) and outer ring (cup) can be mounted independently. This modularity isn't just for show-it significantly simplifies the installation process and maintenance cycles in complex machinery. Because the rollers are set at a specific contact angle, the 33113 excels at maintaining system rigidity and reducing friction under high-stress conditions, making it a reliable choice for gearboxes and industrial drive systems.

What sets the 33113 series apart is its ability to provide high operational accuracy even when things get demanding. Often mounted in opposing pairs to handle axial forces from both directions, these bearings are frequently found in automotive hubs, construction equipment, and heavy-duty agricultural machinery. The pressed steel cage is standard, ensuring the rollers stay perfectly aligned even during high-speed rotations (with limiting speeds often reaching up to 5600-6200 rpm depending on lubrication). Whether you are looking for an SKF, Timken, or FAG equivalent, the 33113 offers a standardized, high-fatigue-life solution that keeps downtime to a minimum.
