30309 SING ISB tapered roller bearing

30309 SING ISB Tapered Roller Bearing – Increased Load Capacity and Precise Operation

Product Description

30309 SING ISB is a single-row tapered roller bearing designed to accommodate high radial loads and axial loads acting in one direction. Thanks to the optimized geometry of the raceways and tapered rollers, it ensures high system rigidity, precise shaft guidance, and stable operation even in demanding industrial environments.

The 303 series features increased load capacity compared to lighter tapered series, making it ideal for applications with elevated load requirements. The SING designation indicates single commercial packaging.

Applications

• Industrial gearboxes
• Wheel hubs and running gear systems
• Agricultural and construction machinery
• Production machine drives
• Applications requiring simultaneous transmission of radial and axial loads
