AKN TSNX 522/619 ZA Taconite Seal for Bearing Housings

Description

This is the AKN TSNX 522/619 ZA, a heavy-duty taconite seal designed for superior bearing protection in harsh and contaminated environments. As a non-contact labyrinth seal, it effectively prevents the ingress of solid and liquid contaminants while retaining bearing lubricant. It is suitable for use in standard SNL 522 and SNL 619 series plummer block housings.

FAQ

Taconite seals provide superior protection in highly contaminated environments. Their multi-stage labyrinth design creates a difficult path for contaminants like dust, dirt, and water to enter the bearing housing, while a grease-filled cavity acts as an additional barrier. This is far more effective than simple contact seals, significantly extending bearing life in harsh applications.

Yes, it is recommended to fill the labyrinth cavity with grease. A standard lithium-based grease is usually sufficient, but for optimal performance, you should use a grease compatible with the bearing lubricant. This grease barrier purges contaminants and prevents them from reaching the bearing.

Taconite seals are non-contact labyrinth seals, which means they do not generate frictional heat like contact seals do. This makes them suitable for higher speeds compared to many contact seal types. However, for extremely high-speed applications, you should always consult the manufacturer's speed rating to ensure it meets your equipment's requirements.
