  • The metal case is the exterior (or frame) of the oil seal, the principal function of which is to give rigidity and strength to the seal. The material of the case must be selected depending on the environment where the seals are to be used. Often the metal case is covered by the same rubber material used in the sealing element, which also helps seal the exterior of the oil seal in the housing bore. Common case material types are:

  • If the seal is being fitted to original equipment you may have some influence over the shaft and housing bore finish, but if you are replacing a worn seal you still need to take into account the condition of these 2 essential parts. Check for sharp edges and burrs – particularly on the shaft and housing chamfers or you could ruin the seal before you start up. If the shaft is too worn consider using an M Barnwell Services Shaft Repair Kit.

  • Testing procedures are also outlined in the oil seal standard to ensure consistent quality across different manufacturers. Testing may include procedures such as leak testing, pressure testing, and endurance testing to ensure that the seal can perform as expected under real-world conditions.

  • 2. Industrial Machinery Metal-to-oil seals are used in a variety of industrial machinery, such as pumps, compressors, and turbines, to ensure that fluids remain contained within the system.
  • A high pressure oil seal is essentially a mechanical barrier that seals the interface between moving and static parts, ensuring that oil or other lubricants remain within the system while preventing contaminants from entering. They are typically made from robust materials such as rubber, polyurethane, or PTFE (Teflon), each with unique properties suited to different operating environments and pressures.

  • High-Pressure Rotary seals that are used for high-pressure applications have a solid cross-section, are developed to seal a pressurized lubricant, and possess hydrodynamic waves that encounter the pressurized lubricant. These fluid waves pump lubricant into the engaged sealing interface when the shaft spins.

    The introduction of skeleton
    oil seals
    Generally said that the oil seal refers to the skeleton oil seal.The function of the oil seal is generally to isolate the parts that need lubrication in the transmission parts from the external environment, so as not to let the lubricating oil leak.The skeleton acts like the steel bars in a concrete member to strengthen and keep the seal in shape and tension.According to the structure, it can be divided into single lip skeleton oil seal and double lip skeleton oil seal.The auxiliary lip of the double lip skeleton oil seal plays a dust-proof role, to prevent the outside dust, impurities and so on into the machine.According to the frame type, it can be divided into inner frame oil seal, exposed frame oil seal and assembled oil seal.According to working conditions, it can be divided into inner frame oil seal, exposed frame oil seal and assembled oil seal.According to working conditions, it can be divided into rotating frame oil seal and round-trip frame oil seal.Used for gasoline engine crankshaft, diesel engine crankshaft, gearbox, differential, shock absorber, engine, axle and other parts.

    The skeleton oil seal structure is composed of three parts: oil seal body, strengthening framework and self-tightening spiral spring.The sealing body is divided into the bottom, waist, cutting edge and sealing lip according to different parts.Generally, the inner diameter of the skeleton oil seal in the free state is smaller than the shaft diameter, that is, it has a certain amount of interference.

    Therefore, when the oil seal is loaded on the oil seal seat and shaft, the pressure on the edge of the oil seal and the contraction force of the self-tightening spiral spring produce a certain radial tightening force on the shaft. After a period of operation, the pressure will rapidly decrease and even disappear. Therefore, the self-tightening force of the oil seal can be compensated at any time with the spring.
