  • From this kind of standard immersion testing, one would expect that bisphenol-cured VDF/HFP/TFE fluoroelastomers would not give good service life as oil seals. Similar tests with other elastomers, such as HNBR, silicone, and acrylic rubbers, show less loss of elongation. However, it is found that, in actual service, FKM shaft seals6 have much longer service life than seals of the other elastomers. In a Japanese study of FKM lip seals, rear crankshaft seals from high-mileage automobiles (70,000–280,000 mi ie, 110,000–450,000 km) were collected and examined. No serious oil leakage was found when the seals were removed from the engines. Some deposits were found around the seal lip and on the garter spring holding the lip against the shaft. No surface cracks were found on the seal lip, and only minor crazing on the crankcase side of the flexure portion of the seal in some samples. The seal compositions were not noted, but most were probably VDF/HFP/TFE elastomers with 68–69% fluorine content.

  • One of the primary functions of an oil seal is to create a barrier between two moving parts in a machine. This barrier prevents oil from escaping from the system, which is essential for maintaining proper lubrication and cooling. Without oil seals, the oil would quickly leak out, leading to reduced performance and eventual failure of the machine.
  • In conclusion, the NBR oil seal is more than a mere component; it is a testament to human innovation in the pursuit of industrial perfection. As technology advances, so too will the demand for reliable sealing solutions like NBR. These unassuming heroes continue to secure our industrial operations, ensuring that the heartbeat of modern machinery beats steadily and reliably, driven by the resilience of NBR oil seals.
  • To do this, turn the engine with a socket on the crankshaft pulley bolt until the rotor arm is pointing to the plug contact of the timing cylinder (usually No. 1, check in the car service manual), and the timing marks on or behind the pulley show exactly top dead centre ( TDC ).

  • The humble engine spark plug, a seemingly minor component within the complex machinery of an automobile, plays a pivotal role in ensuring smooth and efficient vehicle operation. These unsung heroes of the automotive world are responsible for igniting the air-fuel mixture in the combustion chamber, a process fundamental to powering internal combustion engines.
  • Once installed, rubber tube gaskets provide a reliable barrier against fluid leaks, maintaining system integrity and preventing potential safety hazards. Regular inspection and timely replacement are necessary to maintain their effectiveness, as over time, gaskets can degrade due to exposure to environmental factors or continuous pressure.
