The labyrinth seal is classified as a non-contact seal, where no friction or wear occurs at the sealing point. This type of seal is particularly suited for high temperatures and high rotational speeds.By inserting O-rings, the labyrinth ring rotates in sync with the shaft. However, for operating temperatures above 110°C, an alternative material for the O-ring must be selected.
- Material: Grey Cast Iron GG20 (Standard)Brand: GLH
- Description: The TS Labyrinth Rings by GLH are unsplit and made of grey cast iron GG20 as standard. For special applications, rings made of alternative materials, such as aluminum, can be manufactured upon customer request. These rings are specifically designed for use in SD Plummer Blocks by GLH and are not interchangeable with other brands.
The TS rings are fixed onto the shaft using a round cord made of NBR (or alternative materials) and come with a round cord included in the package. Each TS seal is individually packed for safe handling.
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.
- Material: Grey Cast Iron GG20 (Standard). Alternative materials (e.g., aluminum) are available upon request.
- Design: Unsplitted labyrinth rings, non-contact seals that provide effective sealing without limiting peripheral speed.
- Customizable: Can be made from alternative materials such as aluminum, based on customer specifications.
- Fixed on Shaft: Mounted onto the shaft using a round cord made from NBR or other alternatives.
- Single Packed: Each TS ring is individually packed, including the round cord for installation.
- Non-Contact Seal: The TS rings are non-contact seals, meaning there is no speed limitation due to direct contact.
- Not Suitable for Outdoor Use: TS rings are not suitable for use in outdoor environments or where moisture or wet conditions are present.

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.
