Germany B+S seals B+S model B+S price

B+S seals are the customary term for general seals; simply put, they are seals for lubricating oil. They are mechanical components 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 the 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 cased oil seal.

B+S seal advantages

1) The oil seal structure is simple and easy to manufacture. Simple oil seals can be molded in one step; even for the most complex oil seals, the manufacturing process is not complicated. Metal-cased 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 little 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 space for oil seals is small, with small axial dimensions, easy machining, and allowing for compact machine design. 4) Oil seals have good sealing performance and a long service life. They have certain adaptability to machine vibration and spindle eccentricity. 5) Oil seals are easy to disassemble and convenient to inspect. 6) Oil seals are inexpensive.

B+S seal precautions

1) Preparation and precautions before startup: a. Comprehensively check whether the mechanical seal, auxiliary devices, and pipeline installations are complete and comply with technical requirements. b. Conduct a static pressure test before starting the mechanical seal 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. 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 or the installation is unreasonable. 2) Installation and shutdown: a. Keep the seal chamber filled with liquid before startup. When transporting solidifying 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. For mechanical seals using an external seal oil system, start the seal oil system first. Stop the seal oil system last after shutdown. c. After stopping a hot oil pump, do not immediately stop the cooling water for the seal oil chamber and face seal. 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. If slight leakage occurs after the pump starts, observe for a period. If the leakage does not decrease after continuous operation for 4 hours, stop the pump for inspection. b. The pump operating pressure should be stable, with pressure fluctuations not exceeding 1 kg/cm². c. During pump operation, avoid cavitation to prevent dry friction of the sealing surfaces and seal damage. d. Frequently check the sealing condition. During operation, if leakage exceeds the standard (no more than 5 drops/min for heavy oil, no more than 10/min for light oil), and there is no improvement trend within 2-3 days, stop the pump to inspect the sealing device.

B+S seal troubleshooting

1) Main factors causing oil seal leakage: Poor sealing of the oil seal is the main factor causing leakage. When the shaft wears and forms grooves, even replacing with a new oil seal may not achieve sealing because the contact pressure between the oil seal lip and the shaft decreases, resulting in insufficient interference fit between the oil seal lip diameter and the shaft diameter after installation. Taking the S195 diesel engine crankshaft oil seal as an example, the main reasons for poor sealing are analyzed as follows: (1) poor manufacturing quality of the oil seal; (2) poor quality of the shaft or bearing; (3) improper use and maintenance; (4) improper installation; (5) improper storage, adversely affected by environmental pollution. 2) Countermeasures for leakage due to poor oil seal sealing: Master basic knowledge to identify counterfeit and inferior products, and purchase high-quality, standard oil seals. During installation, if the outer surface roughness of the shaft diameter is low, or if there are defects such as rust spots, corrosion, or burrs, polish smooth with fine sandpaper or an oil stone. Apply clean engine oil or lubricating grease to the oil seal lip or the corresponding position on the shaft diameter. Apply sealant to the outer ring of the oil seal. Wrap the keyway area on the shaft with hard paper to avoid scratching the oil seal lip. Use special tools to rotate and press the oil seal inward; never hammer or force it, to prevent deformation of the oil seal or breaking the spring, which would cause failure. If lip flipping, spring detachment, or oil seal skewing occurs, it must be removed and reinstalled. Note: Do not arbitrarily tighten the inner spring when the shaft diameter is not worn and the oil seal spring tension is sufficient. Oil seals used in machinery generally operate under harsh conditions, with large environmental temperature differences, much dust, and frequent machine vibration causing changing stress conditions on components; therefore, frequent inspection, maintenance, and upkeep are required. If the shaft diameter and bearing are severely worn, or if the oil seal rubber ages or the spring fails, repair and replace the corresponding parts in time. Troubleshoot abnormal heating of components or assemblies in time; avoid mechanical overspeed and overload operation to prevent increased temperature at the oil seal lip, rubber aging, and premature lip wear. Frequently check the engine oil level. If there are too many impurities in the engine oil, such as alloy powder or metal iron filings, completely replace with new engine oil. The brand and quality of the replaced engine oil must meet seasonal requirements. It is recommended to add Metaltite Super Sealant & Lubricant to the engine oil. It is an excellent gearbox additive that forms an inert material film on components, which can reduce oil seal leakage, extend the service life of oil seal gears, and reduce gearbox noise. The use of this Metaltite super seal lubricant will not contaminate the oil or cause deterioration.
