Reliable housing sealing by Skf

Practical benefits

Outstanding protection from contamination: You safeguard your bearing housing against harsh dirt and foreign particles, significantly extending overall component life.
Effective lubricant retention inside: The lip seal reliably keeps grease inside the housing while allowing excess lubricant to purge during relubrication.
Reduced friction during operation: You minimize heat generation and mechanical wear due to low-friction performance, ensuring smooth shaft rotation at all times.

In a nutshell

The right choise for

With the Skf txl 511 double-lip seal, you effectively protect your bearing housing against dirt, dust, and moisture. Engineered with an internal gap-type design for 50 mm shafts and housings such as the Skf snl series, it directly replaces the older Skf tsn 511 L series. Featuring an inside diameter of 50 mm, an outside diameter of 75.5 mm, and a width of 12 mm, it fits precisely into the housing groove. Its low-friction design reduces heat build-up and mechanical wear while reliably retaining grease and allowing excess lubricant to purge during relubrication, preventing premature bearing failure and keeping your machinery running smoothly.
