Germany Krautzberger seals Krautzberger model Krautzberger price

Krautzberger seals are materials or components that prevent leakage of fluids or solid particles from adjacent mating surfaces and prevent external contaminants such as dust and moisture from entering machinery. The recommended storage temperature for seals is below 30 °C to avoid high-temperature aging. Seals can be divided into two main categories: static seals and dynamic seals. Their primary function is to prevent leakage of fluids or solid particles from adjacent mating surfaces and to prevent external contaminants such as dust and moisture from entering machinery. Static sealing refers to tightly sealed chambers and containers; seals are also used for stamps on documents and wills.

Krautzberger seal operating principle

An oil film controlled by the lip of the oil seal exists between the oil seal and the shaft, and this oil film has fluid lubrication characteristics. Under the action of liquid surface tension, the stiffness of the oil film causes a meniscus to form at the air-contact end, preventing leakage of the working medium and thereby achieving sealing of the rotating shaft. The sealing capability of an oil seal depends on the thickness of the oil film on the sealing surface. If the thickness is too great, the oil seal will leak; if it is too small, dry friction may occur, causing wear on the oil seal and shaft. If there is no oil film between the sealing lip and the shaft, overheating and wear are likely. Therefore, during installation, some oil must be applied to the sealing ring, and the skeleton oil seal must be kept perpendicular to the shaft axis. If not perpendicular, the sealing lip of the oil seal will wipe the lubricating oil off the shaft, leading to excessive wear of the sealing lip. During operation, it is ideal for a slight amount of lubricant to seep from the housing to maintain an oil film on the sealing surface.

Krautzberger seal applications

Skeleton oil seals are widely used in aviation, automotive, motorcycle, railway, vehicle, ship, home appliance, and construction machinery industries. They are suitable for sealing rotary and reciprocating motion. They are installed on heavy-duty engines, gearboxes, axles, ships, cylinders, and other components. Their main purpose is to prevent penetration of the sealed medium (gas, liquid) and entry of external foreign matter into the body. Precautions: Ordinary oil seals have a very limited pressure range, generally 0.03 MPa. This pressure is typically generated by the height difference of the lubricating oil itself. If higher pressure sealing is required, select high-pressure oil seals (generally capable of withstanding up to 1 MPa) or choose other sealing forms.

Krautzberger seal installation precautions

1) Pay close attention during installation to avoid installation deviations. Tighten the gland after aligning the coupling. Bolts should be tightened evenly to prevent tilting of the gland face. Check all points with a feeler gauge; the error must not exceed 0.05 mm. Check the fit clearance (i.e., concentricity) between the gland and the outer diameter of the shaft or shaft sleeve. It must be uniform around the circumference. Check all points with a feeler gauge; the permissible error must not exceed 0.01 mm. 2) Compress the spring according to specifications. Excessive or insufficient compression is not allowed. The required error tolerance is 2.00 mm. Excessive compression increases specific face pressure, accelerating face wear. Insufficient compression results in inadequate specific pressure, failing to achieve sealing. 3) After installing the moving ring, it should automatically spring back when pressed against the spring. 4) Installation position requirements: To ensure stable operation, long service life, and low leakage performance of the mechanical seal, correct installation on the machine is crucial. Before installing the mechanical seal on the machine, carefully compare it with the general assembly drawing to confirm that all parts are ready. Check for abnormalities such as scratches or damage on the sealing faces of the friction pair and sealing rings. Also check for scratches on the shaft or shaft sleeve surfaces and flanges that contact packing and sealing rings (O rings). If any abnormalities are found, replace or repair before use. During actual installation, do not bring excess parts to the site. If parts remain after installation, it indicates missing components; if parts are insufficient, it means unnecessary components were assembled, thus serving as a self-check during installation.
