O-ring "Characteristics and Sealing Principle"

O-ring "Characteristics and Sealing Principle"

[Sample available] Explaining the characteristics of O-rings and the principle of sealing.

O-rings are compressed when installed in a groove because the depth of the groove is smaller than the thickness of the O-ring. This amount of compression is called "crush white." At low pressure, the sealing action is performed by the rubber elasticity of the O-ring. When hydraulic pressure is applied from one side, a reaction force greater than the applied hydraulic pressure occurs. This is referred to as the O-ring's self-sealing action. 【Features】 ■ Small volume at the installation part ■ Simple structure, easy to install and remove ■ A wide variety of materials available, usable over a broad temperature range ■ Can effectively seal under alternating pressure from both sides ■ More economical compared to other packings ■ Abundant stock for quick delivery *Samples are available upon request. If you would like a sample, please apply through the [Contact Us] section. *Product documentation can be viewed from the [Download] section.

O-ring "How to Use Backup Rings"

O-ring "How to Use Backup Rings"

"Sample available" explains the use of backup rings.

The hardness of O-rings comes in type A durometer hardness Hs70 and Hs90, with Hs90 being specified for general high-pressure use. However, Hs70 can also be used for the same high-pressure applications with the use of backup rings. At high pressure, there can be protrusion from the gap in the shaft. This protrusion is determined by the hardness of the O-ring, the gap between components, and the pressure. Even in low-pressure situations where protrusion is not an issue, it helps prevent accidents such as fraying and twisting damage, which account for the majority of O-ring failures, thus extending the lifespan of the O-ring. 【Product Naming (Example)】 The naming of backup rings consists of the standard number or standard name, type symbol, and the O-ring call number. ■ Spiral JISB2401-4 (Standard Number), T1 (Type Symbol), P20 (Ring Call Number) ■ Bias Cut JISB2401-4 (Standard Number), T2 (Type Symbol), P20 (Ring Call Number) ■ Bias Cut JISB2401-4 (Standard Number), T3 (Type Symbol), P20 (Ring Call Number) *Samples are available upon request.

Twisted spring SWP-AΦ6.0 torsion spring

Twisted spring SWP-AΦ6.0 torsion spring

The Shin-Kin type winding machine can process wire diameters up to Φ10mm.

The material used is "Piano Wire Type A, SWP-A." Due to the wire diameter of Φ6.0 being thick, it is processed using a core wire type winding machine. The core wire type winding machine can process up to a maximum of Φ10mm. After winding, both ends are manually raised, and heat treatment (low-temperature annealing) is performed to remove processing strain. The surface treatment is "trivalent chromate plating + baking." If you have any issues with springs, please feel free to consult us. Our technical staff will respond carefully.

Twisted spring, torsion spring, spring index

Twisted spring, torsion spring, spring index

According to JIS standards, a spring index of "4 or more and 22 or less" is desirable.

The material used is "spring stainless steel wire SUS304-WPB." The wire diameter is Φ0.4. An important index in the design and processing of springs is the spring index. The spring index is a value that serves as a guideline for the difficulty of processing a spring, calculated by dividing the average coil diameter by the wire diameter. A small spring index results in a tight and difficult winding, while a large spring index leads to a loose and unstable winding. According to JIS standards, a spring index of "4 or more and 22 or less" is considered desirable. This spring has an average coil diameter of 12mm and a wire diameter of 0.4mm, resulting in a spring index of 12mm ÷ 0.4mm = 30. This indicates a spring index that exceeds 22, making it a loose and unstable winding pattern; however, it seems to be wound quite neatly. If you have any concerns regarding springs, please feel free to consult us. Technical Contact: Ujiie Phone: 0235-22-0407 FAX: 0235-22-0546 Email: web@tohj.com Tsuruga Spring Co., Ltd. for springs.

Double torsion spring SUS631-WPC Φ1.2

Double torsion spring SUS631-WPC Φ1.2

"SUS631-WPC" is a spring material with high strength and excellent heat resistance.

The material used is "spring stainless steel wire SUS631-WPC." "SUS631-WPC" is a higher strength material compared to the general-purpose spring material "SUS304-WPB" and is often used in applications requiring heat resistance. The heat resistance temperature (permissible use temperature) is approximately 340 degrees for "SUS631-WPC" and about 290 degrees for "SUS304-WPB." "SUS631-WPC" is a precipitation-hardened material that acquires the required strength and heat resistance through heat treatment after spring forming. This heat treatment is referred to as precipitation hardening or aging treatment, with a heat treatment temperature of 470 degrees ± 10 degrees and a heat treatment time of 60 minutes as specified by JIS standards. This spring is called a "double torsion spring," and it has a shape where two torsion coil springs are connected. The left and right coils operate independently, so calculations for moments and lifespan are generally performed separately for each side. (In cases where the dimensions and usage are exactly the same, calculations can be completed for just one side.)

Double Torsion Spring SWP-AΦ3.2

The double torsion spring has a shape formed by connecting two torsion coil springs. It is also called a double kick spring. Typically, the left and right coils have the same specifications, but if they differ, moments and lifespans are calculated separately. The calculation uses the formulas for torsion coil springs. The material of this spring is a steel-based spring material "Piano Wire Type A, SWP-A." After forming, it undergoes heat treatment (low-temperature annealing) and is coated with anti-rust oil. If you have any issues with springs, please feel free to consult us. Tsuruoka Spring Co., Ltd.

[Case Study] Troubles with Rubber Products: O-Rings

[Case Study] Troubles with Rubber Products: O-Rings

Seal by filling the gaps between the parts with rubber to prevent the liquid inside from leaking!

If the molding temperature and molding time of the O-ring are insufficient, the force trying to return the O-ring to its original shape becomes weak, and it remains compressed, resulting in gaps between the components. As a result, the liquid that was sealed by the O-ring leaks out, causing problems. However, the O-ring is fitted into the groove of the assembled components and compressed to fill the gap with rubber. By filling the space between the components with rubber, it seals to prevent the liquid inside from leaking, and the force of the compressed O-ring trying to return to its original shape can close the gaps between the components. [Case Study] ■ Issue - Insufficient molding temperature and molding time of the O-ring lead to gaps between components. ■ Solution - Fill the gaps between the components with rubber to seal and prevent the liquid inside from leaking. *We also accept online meetings. If you would like an explanation about rubber or have any projects you are considering, please feel free to let us know. *For more details, please do not hesitate to contact us.

[Column] Means of "Realization" Necessary for Design Engineering

[Column] Means of "Realization" Necessary for Design Engineering

In the 5th session, we will focus on the means to "realize" ideas and explain sdtech's approach to design engineering!

In the previous fourth session [“Ideas” necessary for design engineering], we explained design engineering as a means to discover “what to conceive and how to realize it” as the original upstream process of design and development. This time, we will introduce “how to realize it.” Recently, in application development required for products and services, by utilizing various tools and services, the process of prototyping what has been defined in requirements and design, and evaluating the validity of the incorporated requirements has become more efficient, although it cannot be said to be “easy.” By advancing digitization within the development team, efficiency has been improved. It is important not to eliminate the “ideas” generated in the previous process merely as theoretical discussions but to make them tangible. This allows for the identification of areas for improvement and better requirements during the concretization process, and it also enables prioritization towards “realization.” *For detailed content of the column, please refer to the related links or download the PDF. If you have any questions or concerns, please feel free to contact us.
