Overview
SKF TSN-507-L bearing seal is a premium four-lip housing seal engineered for contamination control in split plummer block housings. SKF SNL housing seals are the first barrier against contamination, protecting internal bearing components and lubricant from dust, moisture, and debris. Four-lip seals are radially split and easy to mount, making them ideal for field maintenance and replacement applications.
Key Features
- Four-lip design replaces former double-lip seals and generates less friction, which enables higher shaft speeds
- Thermoplastic polyester elastomer material for durability and reliability
- Operating temperature range of -40°C to +100°C
- One seal pack contains two complete seals (four halves) for convenience
- Designed for SNL Plummer Block housings and compatible bearing housings
- For highly contaminated environments, SKF recommends this as part of a three-barrier solution that extends bearing service life
Technical Specifications
- Shaft diameter (da): 30 mm
- Seal groove diameter (Dc): 54.5 mm
- Width (B): 12.5 mm
- Weight: 0.017 kg per seal
- Material: Thermoplastic polyester elastomer
- Seals per pack: 2 (4 halves)
- Operating temperature: -40°C to +100°C
- Seal type: Four-lip radially split design
Typical Applications
This cost-effective sealing solution can have a significant impact on bearing service life as contaminants have to pass through multiple barriers to reach the bearing. Suitable for:
- Agricultural and heavy equipment
- Conveyor systems
- Heat-treatment and processing machinery
- Industrial automation and motion control equipment
- Any application requiring SNL or SNH series plummer block housings with 30mm shaft diameter
