Among rotary spring-energized seals, there are mainly two types: RC2055 and RC2056. Ruichen Seals has been studying the development and manufacturing of seal products for many years. According to different situations and different needs, it has perfected more detailed designs.
RC2055 is a rotary pan-plug seal, RC2055-B is a rotary toothed seal, and RC2055-C is a rotary Y-shaped combination seal. The grooves of the three are interchangeable. They are high-function seals with unidirectional pressure applied to rotating shafts. Among them, the RC2055 rotary pan-plug seal is composed of stainless steel springs and high-function plastics. When using RC2055-B and RC2055-C, it is necessary to reasonably select the matching elastomer materials.
RC2056 is a rotary pan-plug seal, and RC2056-B is a rotary Y-shaped combination seal. The grooves can also be interchanged. It is also suitable for use in rotating shafts. Among them, the RC2056 rotary pan-plug seal is composed of stainless steel springs and high-function plastics. When using RC2056-B and, it is necessary to reasonably select the matching elastomer materials.
Product features and applications:
Product Features:
High Performance: Stainless steel springs and high-function plastics are combined to ensure excellent sealing performance and durability.
Interchangeability: The groove design of the products in the series is the same, which enables interchangeability and flexible adaptation to different working conditions.
Widely applicable: Suitable for one-way pressure sealing of rotating shafts to meet diverse industrial needs.
Optional elastomers: RC2055-B, RC2055-C and RC2056-B support the selection of matching elastomer materials according to working conditions to improve adaptability.
Application scenarios:
One-way pressure sealing of rotating shafts is suitable for industrial equipment, engineering machinery, hydraulic systems, etc.
Occasions where high-function sealing is required, such as petrochemicals, energy equipment, heavy machinery, etc.
Technical advantages:
Stainless steel springs provide stable radial force to ensure long-term sealing effect.
The combination of high-function plastics and elastomer materials is suitable for high pressure and high speed working conditions.
The groove interchangeable design simplifies installation and maintenance and reduces the cost of use.
Usage suggestions:
Select the appropriate seal model and elastomer material according to the specific working conditions.
Ensure the groove is clean during installation to avoid damage to the seal.
