The 33111/P6 tapered roller bearing is a high-precision bearing solution designed for demanding industrial applications that require enhanced dimensional accuracy, rotational stability, and reliable combined load support. As a single-row tapered roller bearing manufactured with P6 precision tolerance, it provides improved running accuracy and reduced vibration compared to standard tolerance bearings.

This bearing is engineered to efficiently carry high radial loads together with substantial axial loads in one direction, making it suitable for precision gear systems, industrial transmissions, and high-performance mechanical assemblies.

Precision Engineering and High-Accuracy Design

The 33111/P6 tapered roller bearing is manufactured from premium-grade bearing steel with precision-ground raceways and carefully profiled tapered rollers. The P6 tolerance class ensures tighter dimensional control, improved concentricity, and enhanced rotational accuracy.

The tapered roller geometry allows optimal load distribution across the rolling elements, minimizing internal stress, friction, and heat generation during operation. The improved precision level reduces vibration and noise, making this bearing ideal for applications requiring smoother rotation and higher performance consistency.

Its reinforced internal structure enhances mechanical rigidity while maintaining long-term reliability under continuous heavy-load conditions.

Technical Specifications of 33111/P6 Tapered Roller Bearing

The 33111/P6 tapered roller bearing has an inner diameter of 55 mm, an outer diameter of 95 mm, and a total width (T) of 30 mm. With an approximate weight of 0.88 kg, it offers a compact yet robust configuration suitable for precision-driven and heavy-duty applications.

In terms of load capacity, the bearing provides a dynamic load rating of 115.6 kN and a static load rating of 157 kN, enabling it to handle significant radial loads while effectively supporting axial forces in one direction. The P6 precision class improves running accuracy without compromising structural strength.
