Overview
The CR 41425 is a single-lip radial oil seal manufactured by SKF Chicago Rawhide, engineered to retain lubrication and exclude contaminants in industrial drivetrain applications. With bore diameter of 105 mm, outer diameter of 130 mm, and thickness of 12 mm, this seal is a standard component for Hansen reducers, industrial gearboxes, and similar rotating equipment where shaft sealing is critical.
Key Features
- Single-Lip Design: Optimized for efficient sealing with minimal friction on shaft rotation
- Garter Spring: Included spring maintains consistent radial pressure for reliable contact
- Nitrile Rubber Construction: Chemical-resistant material suitable for oil-filled housings
- Compact Profile: 12 mm width fits standard mounting grooves without major redesign
- Hansen Reducer Compatibility: Factory-matched for Hansen brand speed reducers and similar industrial gearbox applications
