Single Acting Step Seal Rings

Features:

One-way seal design:

• The acting Step Seal ring design contains two sealing rings, one interface, and no sealing fluid chamber. This means they must operate in dry conditions or must be lubricated and cooled by liquid products.
• This type of sealing ring can only provide effective sealing performance in one direction.
• When the piston rod moves in one direction, the sealing ring can seal reliably; but when the piston rod moves in the opposite direction, the sealing ring does not work.
• This one-way sealing feature makes it more suitable for situations where only one-way sealing is required.

Ladder structure:

• The cross-section of the sealing ring presents a stepped design.
• This structure can better fit the movement trajectory of the piston rod and improve sealing performance.
• The stepped design also increases the overall rigidity and stability of the seal.

Suitable for low voltage applications:
Single mechanical seals are typically used to seal non-critical substances and low-pressure applications because they can allow leakage around the container, which is not technically tight compared to double and triple mechanical seals.

Functions:

• Piston rod one-way seal:
  This kind of sealing ring can only provide effective sealing in one direction and is used when the piston rod only needs to move back and forth in one direction.
  It can reliably prevent the working medium from flowing from one end of the piston rod to the other end, ensuring the sealing of the system.

• Improve sealing performance:
  The stepped structure can better fit the piston rod surface and reduce leakage.
  The sealing contact area is increased and the sealing performance is improved.

• Improve stability:
  The stepped structure improves the rigidity and stability of the sealing ring itself.
  It can adapt to the piston rod's movement and reduce the sealing ring's deformation and damage.

• Extended service life:
  Excellent wear-resistant materials ensure the durability of the sealing ring.
  It can work stably for a long time in the temperature range of -40°C to 120°C.

Single Acting Step Seal Rings are mainly used in the following scenarios:

1. Hydraulic cylinder and air cylinder: used as a one-way sealing ring for the piston rod, used in hydraulic and pneumatic actuators.
It can reliably prevent the working medium from flowing from one end of the piston rod to the other end.

2. Construction machinery: widely used in hydraulic systems of construction machinery such as excavators, loaders, forklifts, etc. Provides a stable and reliable one-way seal for the piston rod.

3. Aerospace equipment: used for piston seals in aviation and aerospace hydraulic systems. It can maintain good sealing performance even in harsh high-altitude environments.

4. Automobile power system: used in the sealing of hydraulic components such as automobile gearboxes and steering systems.
Reliable sealing performance ensures the normal operation of these critical systems.

5. Industrial equipment: widely used in hydraulic and pneumatic systems of various industrial equipment. Such as piston seals for injection molding machines, presses, oil injection pumps, and other equipment.

6. Agricultural machinery: used for sealing hydraulic systems of agricultural machinery such as tractors and harvesters. It can maintain good sealing performance even in harsh agricultural environments.
