The Taconite seal is the most effective solution for protection against water, mud, and coarse contamination. The lubrication port allows the labyrinth to be filled with grease, further enhancing the sealing performance.
- Material: Grey Cast Iron GG20Brand: GLH
- Description: The TAU Taconite Seal by GLH is a highly effective sealing solution designed for use in harsh environments. GLH TAU seals are combination seals consisting of three stages.
- Stage 1: A TSU-series labyrinth ring
- Stage 2: A radial shaft seal or a V-ring
- Stage 3: A grease chamber, which can be lubricated via a grease nipple for added sealing efficiency.
The entire assembly is encapsulated in a split grey cast iron housing (GG20), making it both durable and reliable.
The introduction of oil through the bores and grooves creates an oil film on the mating surfaces between the sleeve and the bearing. This reduces friction and significantly reduces the forces required for mounting. The bearing slides more easily onto the taper, minimising the risk of surface damage. In addition, independently operable oil inlets for the inner and outer oil grooves facilitate movement of the entire sleeve and bearing assembly after installation.
When oil is forced through the holes and grooves between the sleeve and bearing or between the shaft and sleeve, the bearing to sleeve and sleeve to shaft connections are loosened. As the press fit is released abruptly, the axial movement of the sleeve must be limited by a nut or stop.
- Triple Sealing System: Combines three sealing elements for maximum protection and reliability.
- Stage 1: Labyrinth ring (TSU Series)
- Stage 2: Radial shaft seal or V-ring
- Stage 3: Grease chamber with lubrication capability
- Grease Chamber: The grease chamber is equipped with a grease nipple, allowing easy lubrication for improved performance.
- Durable Housing: The entire system is encapsulated in a split grey cast iron housing (GG20).
- Versatile: Ideal for use in highly contaminated, dusty environments and offers superior protection in extreme conditions.
- High-Speed Performance: Capable of operating at peripheral speeds up to 12 m/s.
Temperature Range: Operates within a temperature range of -40°C to +100°C.
Angular Misalignment Tolerance: Can tolerate up to 0.2° of angular misalignment.

The TAU Taconite Seal is supplied as a set for one housing side. The grease chamber is accessible via a grease nipple for lubrication, ensuring optimal sealing performance in demanding conditions.
Peripheral Speed: Up to 12 m/s
Angular Misalignment: Up to 0.2°
Temperature Range: -40°C to +100°C
Particularly advantageous in mining and similar environments.
Increased durability and maintenance-friendly due to the ability for re-lubrication.
Flexibility through the availability of two sealing types.
Axial labyrinth seal (TNC): Effective sealing solution for axial requirements. Radial labyrinth seal (TAU): Optimal for radial sealing needs
Cast iron is an iron-carbon alloy with a high carbon content, typically between 2.1% and 4%. It is known for its excellent compressive strength, heat resistance, and ease of casting, making it widely used in the construction and mechanical industries. Cast iron is also commonly used in manufacturing cookware and engine components. Despite being brittle and prone to breaking under tensile stress, cast iron provides high stability, durability under compression, and is cost-effective to produce.
