Choosing the wrong materials for an oil seal may result in premature wear, lip hardening, cracks, swelling, and subsequent expensive damage to the machinery in which the seal is used. It is therefore vital to gather all relevant data and consult with experts before purchasing to match the right type of oil seal with your application.
ERIKS

oil seal in motor. They are specially engineered to provide a tight seal that can withstand the rigors of daily use. Without proper oil seals, the motor can suffer from oil leaks, reduced efficiency, and ultimately, complete breakdown.
Another benefit of neoprene foam gaskets is their versatility. These gaskets are available in a variety of shapes, sizes, and thicknesses to meet the specific requirements of different applications. Whether it's a simple O-ring seal or a complex custom gasket design, neoprene foam gaskets can be tailored to fit the unique needs of various industries.

skeleton oil sealing. These foreign particles can cause significant damage to machinery if they enter the system, so it is essential to have a reliable sealing solution in place.

Oil seals increasingly had to meet higher requirements, which is why PTFE was developed in 1980. This variant can better withstand higher engine speeds, higher oil temperatures, longer oil intervals and modern lubricants. In addition, the oil seal contains a wider contact surface, which ensures less wear.
Some aspects to consider when selecting this component are:
