Piston Ring

Piston Ring

  • PC ring type: single oblique cut form, cut 45 degrees, long air leakage channel, piston rotates during reciprocating motion, not recommended for use on uncured aluminum pistons. Conventional ring type, easy to install.
    The product advantage comes from high-quality materials and customized design. The independently developed high-performance polymer formula, processed by European and American professionals, combines self-lubricating, high wear resistance, and high mechanical strength characteristics. It is suitable for various gases such as air, natural gas, hydrogen, and extreme temperature and pressure environments. There are also special materials such as 9E, 9K, 9B that accurately match different working conditions such as oil/oil-free, high and low pressure. The company can customize the design of product structure dimensions and complete selection verification based on compressor piston materials, gas types, temperature and pressure parameters, and other operating indicators to ensure compatibility and reliability.

The cylinder ring products of Nirvana Machinery (Suzhou) Co., Ltd. are specially developed for the core sealing and transmission needs of compressors, covering two core categories: piston rings and rider rings. With precise design, diverse selection, and high-quality materials, they are suitable for various complex working conditions and provide reliable guarantees for the efficient and stable operation of compressors.
The core function of the product is outstanding, and the piston ring has the triple functions of sealing, reducing wear, and guiding. Through gas pressure difference, the gap between the piston and the cylinder is sealed to prevent high-pressure gas leakage and impurity intrusion, while reducing friction loss and ensuring stable piston movement trajectory; The rider ring focuses on guiding and protecting, avoiding direct contact between the piston and the cylinder liner, and extending the service life of the equipment.


In terms of product selection, piston rings offer a wide range of types to adapt to different radial thicknesses and operating conditions:

PA:The single straight incision form is not easy to break, has high strength, short air leakage channel, and does not rotate when the piston reciprocates. Therefore, it has good performance on aluminum pistons that have not been hardened.
PB:The double straight cut form has a low risk of breakage, high strength, short airflow leakage channel, and does not rotate when the piston reciprocates. Therefore, it has good performance on aluminum pistons that have not been hardened.
PC:Single oblique incision form, 45 degree incision, long airflow leakage channel, piston will rotate during reciprocating motion, not recommended for use on uncured aluminum pistons. Conventional ring type, easy to install.
PD:Double oblique incision form, incision angle of 45 degrees, long airflow leakage channel, piston will rotate during reciprocating motion, not recommended for use on uncured aluminum pistons. Conventional ring type, small cylinder diameter and use of hard materials.
PE:Single cut form, no airflow leakage channel, efficient sealing effect, not recommended to use fragile materials, suitable for lightweight gases, conventional ring type, easy to install.

PF:Double cut form, no airflow leakage channel, efficient sealing effect, not recommended to use fragile materials, suitable for lightweight gases, conventional ring type, easy to install.
