Overview
The SKF TSN507L is a four-lip bearing seal engineered for use with SKF SNL plummer block housings. These TSN507L SKF Four Lip Seals can fit into the SNL Plummer Block housings and offer protection from outside elements. The four-lip seals replace the former double-lip seals and are more effective than the double-lip design while generating less friction, which enables higher shaft speeds. This seal is ideal for machinery requiring robust contamination control and extended bearing protection.
Key Features
- Four-Lip Design: Generates less friction than double-lip designs, enabling higher shaft speeds
- Thermoplastic Elastomer Material: Thermoplastic elastomer material construction for durability and chemical resistance
- Contamination Barrier: SKF housing seals are the first barrier against contamination
- Drop-In Compatibility: Direct replacement for SNL series 2, 3, 5, and 6 housings
- New in Box Condition: Factory-sealed, ready for immediate installation

Typical Applications
The SKF TSN507L bearing seal is used across a range of industrial equipment where bearing protection is critical. Common applications include conveyor systems, gearboxes, electric motor bearings, and rotating shaft assemblies in manufacturing environments. For highly contaminated environments, SKF recommends the three-barrier solution, which is a cost-effective sealing solution that can have a significant impact on bearing service life as contaminants have to pass through three barriers to reach the bearing.
