FAQ

What is the main advantage of a labyrinth seal like the TSNX 513 S over a standard contact seal?

The primary advantage is its non-contact design. This means there is no friction on the shaft, which prevents shaft wear, reduces heat generation, and allows for much higher rotational speeds. It’s ideal for applications where friction losses are a concern.

Is the TSNX 513 S a complete sealing set for one side of the housing?

Yes, the TSNX 513 S is designed to provide a complete seal for one side of a compatible 513 series plummer block housing. It works by creating a complex path that makes it difficult for contaminants to enter, requiring no other sealing parts for its primary function.

What kind of lubrication is best suited for a bearing protected by this type of seal?

Labyrinth seals are compatible with both grease and oil lubrication. For grease lubrication, the seal helps retain the grease within the bearing housing. For oil lubrication, they are effective at preventing oil leakage, especially when combined with features like an oil return groove in the housing.
