SKF Seal, 55mm ID, 78mm OD, 8mm

When you're looking for a simple and effective sealing solution for your spherical roller bearings, turn to this double lip seal from SKF. The felt housing forms a small buffer between the component and shaft, transforming the bearing into a non-contact device that accommodates relatively high-speed operations. As the seal's material acts a reservoir for lubricants, it supports continuous free axial movements. It also protects shafts from dust and other contaminants to limit the time you need to spend on maintenance.

• 55mm inner diameter makes it a good fit for larger pieces
• Easy to install, thanks to the flexible material
• Combination of felt, aluminium and NBR materials to withstand general wear and tear
• Light weight of only 60g adds minimal drag to bearings and shafts

• Gearboxes
• Wind turbines
• Aerospace applications
• Paper manufacturing systems

A non-contact bearing seal is fixed to the outer ring. This means there's no direct contact with or pressure on the inner ring, which allows the shaft to move freely.
