Overview
The SKF LOR130 is a PosiTrac labyrinth bearing seal engineered for pedestal-type bearing housings in industrial motion control and rotating machinery applications. This aluminum-constructed seal delivers multi-stage labyrinth protection, isolating internal bearings from external contamination, moisture, and dust ingress. SKF’s precision engineering ensures the seal operates concentrically with the shaft, maintaining effective sealing performance across extended service intervals.
Key Features
- Multi-stage labyrinth design for enhanced sealing effectiveness
- Aluminum construction for lightweight and corrosion-resistant performance
- Bore diameter of 5 7/16 inches (138 mm) for standard pedestal housing applications
- O-ring bore design enables seal rotation with the shaft for reduced wear
- No lubrication required; dry-running design minimizes maintenance
- SKF PosiTrac technology ensures consistent, reliable sealing
