32309 NKE - Tapered Roller Bearing 45x100x38,25

Heavy-duty tapered bearing for combined loads

High durability in demanding industrial applications

Reliable component for professional bearing units

Technical Specification and Application

The 32309 NKE 45x100x38,25 is a single row tapered roller bearing engineered to support combined radial and axial loads. Its tapered roller and raceway geometry ensures efficient load distribution, high stiffness, and precise shaft guidance under heavy-duty operating conditions.

With dimensions 45x100x38,25 mm, this bearing is commonly used in gearboxes, hubs, transport systems, and medium to heavy industrial machinery. Compared to a standard ball bearing, a tapered roller bearing offers significantly higher axial load capacity and improved rigidity, making it ideal for applications exposed to dynamic forces and shock loads. This results in high durability and stable long-term performance.

The 32309 NKE can operate as a single bearing or as part of a complete bearing unit. In many industrial designs, it is mounted in pairs within a housing assembly to handle axial loads in both directions. Proper mounting and axial clearance or preload adjustment are essential to maximize service life and operational reliability.

Designed for demanding industrial applications, this tapered roller bearing provides consistent performance in continuous-duty environments. It is suitable for machine builders, maintenance teams, and B2B customers requiring dependable load support and long service intervals.
