31309 SKF Taper Roller Bearing

Description

45x100x27.25mm

Support high radial and axial loads with stable, controlled rotation. That is the core advantage of the 31309 SKF taper roller bearing. Its tapered roller design is engineered to manage combined loads efficiently, which matters in assemblies where both directional force and rotational accuracy affect service life. In practical terms, this helps reduce premature wear, maintain alignment and keep machinery running with less disruption.

SKF is specified where dependable bearing performance is critical, and the 31309 format is built for applications that demand precise load handling. The taper roller arrangement increases contact area compared with simpler bearing types, so load is distributed more effectively across the rolling elements. The result is stronger support under pressure, smoother running characteristics and greater confidence in demanding operating conditions.

• Taper roller bearing configuration for combined load applications, helping equipment cope with both radial and axial forces at the same time.
• 27.25 mm width provides a defined installation profile, making it easier to match the bearing to housings and shaft arrangements where dimensional accuracy matters.
• 0.95 kg unit weight gives the bearing the mass expected for robust mechanical support, offering a solid balance between strength, handling and installation practicality.
• SKF manufacture gives you a bearing specified from a globally recognised engineering brand, supporting confidence in fit, function and long-term reliability.

At 27.25 mm wide, this bearing is suited to assemblies where the installed width must be controlled to maintain correct internal clearance and component positioning. Its 0.95 kg weight indicates a substantial, application-ready unit designed for serious load-bearing duties rather than light, low-demand use. For maintenance teams and buyers, those are not just numbers. They are key selection points that influence fitment, handling and operational stability.

The 31309 SKF taper roller bearing is a precise choice for roller bearing applications that cannot tolerate guesswork. It brings together a proven tapered roller layout, a clearly specified 27.25 mm width and a robust 0.95 kg construction in one dependable component. Fit the correct bearing. Protect the assembly. Maintain performance with a bearing specified for the job.
