2. Piston Ring Essential Details:
1. Material: Piston rings are typically made from cast iron,
ductile iron, steel, or advanced materials like stainless steel,
chrome-plated steel, or nitrided steel, chosen for their
durability, heat resistance, and wear characteristics.
2. Types: Piston rings come in various types, including compression
rings, oil control rings, and scraper rings, each serving specific
functions in the engine.
3. Size: Piston rings are available in different sizes to fit the
bore diameter of the engine cylinder. They are often categorized by
dimensions such as diameter, width, and thickness.
4. Design: The design of piston rings may vary based on engine
requirements, including ring profile (e.g., rectangular,
barrel-faced), ring groove shape, and ring face coatings for
enhanced wear resistance and reduced friction.
5. Function: Piston rings seal the combustion chamber, prevent gas
leakage, and maintain compression within the cylinder. Oil control
rings regulate oil consumption and prevent oil from entering the
combustion chamber, while scraper rings remove excess oil from the
cylinder walls.
6. Installation: Proper installation of piston rings is essential
for engine performance and longevity. Rings must be correctly
positioned in the piston ring grooves with the proper end gap
clearance and orientation.
7. Maintenance: Regular inspection and maintenance of piston rings
are necessary to ensure optimal engine performance. This may
include checking for wear, replacing worn rings, and maintaining
proper lubrication to prevent ring sticking or scuffing.
8. Replacement: Piston rings may need replacement if they become
worn, damaged, or fail to maintain proper sealing and compression.
Replacement typically involves disassembling the engine, removing
the piston, and installing new rings according to manufacturer
specifications.
9. Compatibility: When replacing piston rings, it's crucial to
ensure compatibility with the engine make, model, and
specifications to guarantee proper fitment and performance.
10. Manufacturer Recommendations: Following the manufacturer's
recommendations for piston ring selection, installation, and
maintenance is essential to maximize engine efficiency,
performance, and longevity.
3. NFK HIGH-QUALITY SEALS MANUFACTURING EXPERTS:
Product characteristics
Hydraulic special bearing: It is a new type of material designed on
the basis of SF-1P and combined with the working principle of oil
cylinder and shock absorber. It appears wear-resistant under
oil-free conditions. In addition to the advantages of SF-1D, this
product is particularly Suitable for occasions with frequent
reciproion and large lateral force. Its performance is similar to
that of foreign DP4. At present, this product is gradually
replacing SF-1P products, and is suitable for automotive and
motorcycle shock absorbers and various hydraulic cylinders.
Maximum bearing pressure 140N/mm² Friction coefficient μ 0.04~0.20
Applicable temperature range -195℃~280℃ Maximum allowable PV value
(dry) 3.8N/mm²·m/s
Maximum sliding speed 3m/s Maximum allowable PV value (oil)
