Over time, piston oil seals may wear out or become damaged due to normal wear and tear, extreme temperatures, or poor maintenance practices. When this happens, oil leakage can occur, leading to decreased engine performance and potential damage to the engine.

35 47 7 oil seal. This parameter is vital because it determines the seal's ability to withstand pressure and maintain its integrity. Exceeding this limit can lead to deformation, compromising the seal's sealing capacity and potentially causing leaks. Engineers must consider factors such as operating pressure, temperature, and shaft eccentricity to ensure the seal remains within this tolerance.
They can withstand high temperatures without losing their shape or sealing properties, making them ideal for use in high-temperature applications such as power plants, refineries, and chemical reactors They can withstand high temperatures without losing their shape or sealing properties, making them ideal for use in high-temperature applications such as power plants, refineries, and chemical reactorsrubber flange gasket.
The most common oil seals are the ERIKS types R, RST, M and MST, which correspond respectively to types A, AS, B and BS according to DIN 3760/ISO 6194.
Oil seals, often called a rotary shaft seal or grease seal, closes the gap between stationary and moving components in mechanical equipment — most often rotating shafts — helping prevent lubricant escape and stopping harmful materials, such as dirt, from moving in through the clearance. Oil seals are most commonly used in gearboxes, hydraulic cylinders, and related components.

Ultimately, oil seals are devices that help to exclude dust and dirt, etc., while at all times retaining the lubricant in the piece of equipment.
