Tarcon® Loto L Seal

Tarcon® Loto L Seal

It was developed to extend the seal life of the axle system.

It features a very unique concept of sealing only when necessary, thereby reducing friction and significantly saving energy by decreasing fuel consumption. The Tarkanrot L seal consists of a PTFE sealing lip, a rubber jacket, and a metal component for shape stability. It was developed to extend the seal life of axle systems. The patented seal design philosophy operates only when the system is pressurized, meaning that for the majority of the time, the sealing lip is open and away from the surface. This unique concept is exclusive to the Tarkanrot L. For more details, please download and view the catalog.

Spring-loaded seal (explanatory materials and sample provided)

Spring-loaded seal (explanatory materials and sample provided)

Replaceable with O-rings and oil seals! Performs well in harsh environments requiring no lubrication, extreme low temperatures, chemical resistance, and heat resistance!

The "spring-loaded seal" is a high-performance seal that combines a PTFE-based jacket with a corrosion-resistant metal spring. The PTFE jacket has excellent chemical resistance and a wide temperature range, and the metal spring accommodates deformation due to wear and shrinkage or expansion of the seal. It can replace O-rings and oil seals, contributing to the high performance of gas and liquid handling equipment. There is a rich lineup, including options like the "scraper lip," which emphasizes scraping ability. We can propose suitable seal shapes and materials based on fluid, pressure, temperature, and motion conditions. 【Features】 ■ Compatible with both fixed and moving applications ■ Excellent resistance to chemicals and organic solvents ■ Usable at low temperatures of -268°C and high temperatures above 300°C ■ Usable in high vacuum and high-pressure environments ■ A wide variety of materials for jackets and springs *We are currently offering explanatory materials that include basic knowledge about this product and examples of its implementation. Please check it out from "PDF Download." If you would like a product sample, please feel free to contact us.

[Case Study] Replacement of Oil Seal (Lip Seal)

[Case Study] Replacement of Oil Seal (Lip Seal)

Supports small lots and special groove dimensions during trial production! Selects the most suitable seal type for the usage conditions!

【Issues】 When installing the oil seal, the environment becomes harsher as the rotational speed increases, leading to problems such as short lifespan and high heat generation during high-speed motion. 【Improvements and Effects】 The metal ring lip seal and lip seal can be used at speeds exceeding 20 m/s. For applications with rotational speeds exceeding 3 MPa, we recommend using spring-loaded seals. Since the seal lip is primarily made of PTFE, it can be used in dry environments. There is no stick-slip, so there are no issues when restarting equipment or facilities after long periods of inactivity. Based on our experience and know-how, we will select the most suitable seal type for the operating conditions. *For more details, please refer to the PDF document or feel free to contact us.

[Case Study] Replacement of Mechanical Seal (Lip Seal)

[Case Study] Replacement of Mechanical Seal (Lip Seal)

It is also possible to configure the equipment in a more space-saving manner! There is flexibility in the manufacturing dimensions of the seals as well!

【Issues】 When installing mechanical seals, there are concerns about requiring a large amount of space, as well as high costs for implementation and maintenance. 【Improvements and Effects】 Since lip seals are manufactured through machining, there is flexibility in the dimensions of the seals. Additionally, depending on the usage conditions, it is possible to replace with a single seal, allowing for a more compact configuration of the equipment. *For more details, please refer to the PDF document or feel free to contact us.

[Case Study] Replacement of Metal Seals (Spring-Loaded Seals)

[Case Study] Replacement of Metal Seals (Spring-Loaded Seals)

Reusing the seal is possible at the customer's discretion! We are applying surface pressure using the elasticity of the spring!

【Issues】 When installing a metal seal, a mirror finish of generally 0.4Rmax or higher is essential. This has led to problems such as the inability to reuse seals and the hassle of regrinding. 【Improvements and Effects】 The spring-loaded seal uses Teflon as the main sealing material and applies surface pressure using the elasticity of the spring. Therefore, it does not damage the hardware during installation. For fluids that are prone to leakage (such as cryogenic temperatures, helium gas, and hydrogen gas), a finish of 0.4 to 0.8Rmax is required, but generally, a finish of 0.8 to 1.6Rmax is sufficient for use. *For more details, please refer to the PDF document or feel free to contact us.

[Case Study] Improvement Proposal for Hydraulic Cylinder (Spring Loaded Seal)

[Case Study] Improvement Proposal for Hydraulic Cylinder (Spring Loaded Seal)

Inert to most fluids! Also used as a backup ring for rubber seals!

【Issues】 The commonly used packing materials are primarily rubber such as Viton and HNBR, which are considered suitable for high-temperature applications. However, when temperatures exceed 200°C, as is often the case with SN cylinders, deterioration is unavoidable. In severe conditions, there have been reports of cases where packing replacement is necessary every 2 to 3 weeks. 【Improvements and Effects】 The spring-loaded seal combines PTFE, which excels in heat resistance, sliding, and extrusion resistance, with the high-temperature spring characteristics of 17-7PH, achieving sealing performance and long lifespan that were difficult with conventional packings. Practical examples in Japan are steadily increasing, and many end users and cylinder manufacturers have adopted this solution. 【Examples】 (Lab Test) Test Conditions: Unloaded sliding test: 10 reciprocations (full stroke) - 9.8 MPa (100 kg/cm²) pressure resistance: 10 pressure tests (1 minute each) - 20.6 MPa (210 kg/cm²) pressure resistance: 10 pressure tests (1 minute each) *For more details, please refer to the PDF document or feel free to contact us.
