11206203 Φ40 rubber pad Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The 11206203 Φ40 rubber gasket boasts four major advantages: tight sealing, anti-aging properties, strong shock absorption, and easy assembly. It is widely used in heavy machinery such as cranes, excavators, and hydraulic equipment, playing a crucial role in sealing equipment components, buffering vibrations, and preventing slippage. It precisely conforms to equipment interfaces or contact surfaces, blocking fluid leakage, mitigating component vibration, preventing component slippage, ensuring equipment operational stability, preventing component wear, and is compatible with various machine models. Installation is convenient, and it can be put into immediate use.
This product is made of high-quality rubber through precision machining, strictly adhering to industrial sealing and buffer component quality standards. The main body is made of oil-resistant nitrile butadiene rubber (NBR), manufactured through precision molding, vulcanization, and performance testing. It boasts excellent elasticity and toughness, exhibiting outstanding oil resistance, wear resistance, aging resistance, and compression set resistance. It effectively solves problems such as gasket aging, cracking, sealing failure, and poor vibration damping, reducing equipment maintenance costs and extending equipment lifespan. Its optimized circular structure design precisely matches the Φ40 specification interface, resulting in a smooth and flat sealing surface. It is suitable for complex operating conditions involving high pressure, heavy oil contamination, and strong vibration, meeting the core requirements of modern industrial equipment for “sealing, vibration damping, and long-term effectiveness,” while balancing sealing reliability with ease of assembly.
