451950 seals Germany schnorr model 451950 price

451950 seal is the customary term for general seals; simply put, it refers to lubricating oil sealing. 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), isolating the parts requiring lubrication in the transmission assembly from the output parts to prevent lubricating oil leakage. Seals used for static sealing and dynamic sealing (generally reciprocating motion) are called oil seals. The representative form of oil seal is TC oil seal, which is a double-lip oil seal with a self-tightening spring fully covered by rubber. The term oil seal generally refers to this type of tc skeleton oil seal.

451950 seal construction

The skeleton oil seal structure consists of three parts: the seal body, the reinforcing skeleton, and the self-tightening helical spring. The seal body is divided into the bottom, waist, cutting edge, and sealing lip according to different parts. Typically, in the free state, the inner diameter of the skeleton oil seal is smaller than the shaft diameter, meaning it has a certain "interference fit." Therefore, after the oil seal is installed on the oil seal seat and shaft, the pressure of the oil seal cutting edge and the contraction force of the self-tightening helical spring generate a certain radial tightening force on the shaft. After a period of operation, this pressure will rapidly decrease or even disappear; thus, the spring can compensate for the self-tightening force of the oil seal at any time.

451950 seal usage instructions

1) When the gearbox lubricating oil volume is ≤ 7 liters, the addition amount per liter of lubricating oil is 20‐30ml; 2) 7‐15 liters, the addition amount is 15‐20ml per liter of lubricating oil; 3) >15 liters, the addition amount is 10ml per liter of lubricating oil; 4) Oil seals not in temporary use should be stored properly to prevent contamination with oil stains, dust, or exposure to sunlight. 5) When the shaft diameter wears into a "V" shaped groove, causing the contact pressure between the new oil seal lip and the shaft to drop such that it cannot seal oil, the displacement method can be used for compensation.

451950 seal precautions

1) Shaft speed: Due to design and structural reasons, high-speed shafts should use high-speed oil seals, and low-speed shafts should use low-speed oil seals. Low-speed oil seals must not be used on high-speed shafts, and vice versa. 2) Ambient temperature: In cases of higher operating temperatures, polyacrylate or silicone, fluorine, or silicone-fluorine rubber should be selected. Measures should be taken to reduce the oil temperature in the tank. In cases of lower operating temperatures, cold-resistant rubber should be selected. (3) Pressure: General oil seals have poor pressure resistance; excessive pressure will cause the oil seal to deform. Pressure-resistant support rings or reinforced pressure-resistant oil seals should be used under conditions of excessive pressure. 4) Installation eccentricity: If the eccentricity is too large when the oil seal mates with the shaft, its sealing performance will deteriorate, especially at high shaft speeds. If the eccentricity is too large, an oil seal with a "W" shaped cross-section can be used. 5) Shaft surface finish directly affects the service life of the oil seal; i.e., higher shaft smoothness results in longer oil seal service life. 6) Ensure there is a certain amount of lubricating oil on the oil seal lip. 7) Pay special attention to preventing dust from entering the oil seal.
