German amixon seals amixon models amixon prices

amixon seals are a common term for general seals, simply referring to the sealing of lubricating oil. It is a mechanical component used to seal grease (oil is the most common liquid substance in transmission systems, and also refers to general liquid substances). It isolates the components requiring lubrication in the transmission parts from the output components, preventing lubricating oil from leaking. Seals used for static sealing and dynamic sealing (generally reciprocating motion) are called oil seals. The representative form of oil seals is the TC oil seal, which is a double-lip oil seal with a self-tightening spring completely covered by rubber. The term oil seal generally refers to this type of tc skeleton oil seal.

Advantages of amixon seals

1) The oil seal structure is simple and easy to manufacture. Simple oil seals can be molded in one step; even the most complex oil seals do not have complicated manufacturing processes. Metal skeleton oil seals only require processes such as stamping, bonding, inlaying, and molding to combine metal and rubber into the required oil seal. 2) Oil seals are lightweight and consume less material. Each oil seal is a combination of thin-walled metal and rubber parts, consuming very little material, so each oil seal is very light. 3) The installation position of the oil seal is small, the axial dimension is small, it is easy to process, and it makes the machine compact. 4) The oil seal has good sealing performance and a long service life. It has certain adaptability to machine vibration and spindle eccentricity. 5) Oil seals are easy to disassemble and convenient to inspect. 6) Oil seals are inexpensive.

Precautions for amixon seals

1) Preparation and precautions before startup: a a. Conduct a comprehensive inspection to ensure that the mechanical seal, auxiliary devices, and pipeline installations are complete and comply with technical requirements. b b. Perform a static pressure test on the mechanical seal before startup to check for leakage. If there is significant leakage, identify the cause and eliminate it. If ineffective, disassemble, inspect, and reinstall. The general static test pressure is 2~3 kg/cm². c c. Rotate the pump according to its direction of rotation to check if it is light and uniform. If rotation is difficult or stuck, check whether the assembly dimensions are incorrect and whether the installation is reasonable. 2) Installation and shutdown: a a. Keep the seal chamber filled with liquid before startup. When transporting solidified media, use steam to heat the seal chamber to melt the medium. Manual rotation must be performed before startup to prevent sudden startup from causing the soft ring to shatter. b b. For mechanical seals utilizing an external seal oil system, start the seal oil system first. Stop the seal oil system last after shutdown. c c. Do not immediately stop the cooling water for the seal oil chamber and face seal after stopping a hot oil pump. Wait until the oil temperature at the face seal drops below 80 degrees before stopping the cooling water to avoid damaging the seal parts. 3) Operation: a a. If slight leakage occurs after the pump starts, observe for a period of time. If the leakage does not decrease after continuous operation for 4 hours, stop the pump for inspection. b b. The operating pressure of the pump should be stable, with pressure fluctuations not exceeding 1 kg/cm². c c. During pump operation, avoid cavitation to prevent dry friction of the sealing surfaces and seal damage. d d. Regularly inspect the sealing condition. During operation, if leakage exceeds the standard (heavy oil not more than 5 drops/min, light oil not more than 10/min), and there is no improvement trend within 2-3 days, stop the pump to inspect the sealing device.

amixon seal specifications and applications

1) Standard single-lip type: Generally used for sealing mineral oil, water, and other media in high and low-speed rotating shafts and reciprocating motion. Standard oil seals are used in environments with less dust and impurities, resistant to media pressure<0.05MPa, maximum linear speed 15m/s, reciprocating speed<0.1m/s. 2) Standard double-lip type: In addition to the usage characteristics of the above-mentioned S type oil seals, it also provides dust protection. Standard oil seals with a dust lip can prevent dust ingress, resistant to media pressure<0.05MPa, linear speed ≤15m/s. 3) Springless type: Single-lip internal skeleton rubber oil seal without a spring. Generally suitable for low-speed conditions where the sealing medium is lubricating grease. Linear speed ≤6m/s. 4) External skeleton single-lip type: Single-lip exposed skeleton rubber oil seal with a spring, featuring a thin waist, good followability, and good rigidity. Standard oil seals are used in environments with less dust and impurities, resistant to media pressure<0.05MPa. Rotational axis linear speed ≤15m/s. 5) External skeleton double-lip type: Double-lip exposed skeleton rubber oil seal with a secondary lip, featuring a thin waist, good followability, high rigidity, and good concentricity. Standard oil seals with a dust lip can prevent dust ingress, resistant to media pressure<0.05MPa. Rotational speed ≤15m/s. 6) Assembled single-lip type: External skeleton oil seal formed by assembling inner and outer skeletons with rolled edges, featuring high installation precision, fast heat dissipation, and heavy-load characteristics. Suitable for heavy-load conditions under high temperature and high speed, media pressure ≤0.05MPa, maximum linear speed ≤15m/s. 7) Unidirectional return flow type (right-hand, left-hand): Angled ribs are manufactured on the air side of the lip, utilizing fluid dynamics principles to produce a unidirectional pumping action with a return flow effect. Related to the shaft's direction of rotation, the radial force is smaller than that of standard oil seals due to the return flow effect, reducing wear and heat generation, and extending service life. Suitable for media pressure<0.05MPa, rotational speed ≤20m/s. 8) Pressure-resistant type: Short lip and short, thick waist, providing pressure resistance, working pressure ≤3MPa. Suitable for applications with media pressure ≤3MPa, suitable for shaft end oil seals of high-pressure pumps. Generally, the PV value ≤8. Rotational axis linear speed ≤15m/s.
