Another advantage of M8 self-drilling screws is their durability
Butterfly screws also offer versatility in terms of material selection
4. **Securing** Once the screw is fully seated, apply a light torque to ensure the screw is securely fastened. Excessive force could cause the screw to break or the material to splinter Excessive force could cause the screw to break or the material to splinter
The metal case serves as the oil seal’s exterior or frame, providing rigidity and strength to the seal. The case material selection depends on the environment in which the seal will operate. Often, the same rubber material used in the seal element covers the case to help seal the exterior of the oil seal in the housing bore.
Advantages:
– Very good fitting stability avoiding pop-out of the seal
– Modern lip design provides low radial forces
– Superior radial stiffness, especially for very large diameters
– Cost effective for expensive elastomer materials
– Suitable for use in combination with axial seal
Conventional oil seals
In conclusion, neoprene foam gaskets offer a combination of durability, sealing efficiency, insulation performance, and versatility that make them an indispensable component in many industrial and commercial applications. With their outstanding properties and reliable performance, neoprene foam gaskets continue to be a popular choice for sealing and insulation solutions in diverse industries.

The depth of the bonded seal can be less and the space between the bore and the outside diameter can be changed for ease of fitting. The bonding of rubber to metal is an important factor to be considered in the manufacture of such seals and should be considered carefully, since failure of the bond will cause the seal to fail. The metal case of the oil seal is usually made from mild steel of deep drawing quality which enables blanking, punching, stamping of the steel to the required dimensions.

Common materials used in oil seals include nitrile rubber, fluorine rubber, silicone rubber, acrylic rubber, polyurethane, polytetrafluoroethylene, etc. When selecting the material of the oil seal, the compatibility of the material with the working medium, the adaptability to the working temperature range and the ability of the lip to follow the rotating shaft at high speed must be considered. When the oil seal is working, the temperature of its lip is higher than the working medium temperature by 20~50°C. Attention should be paid when selecting the oil seal material. The working range of the oil seal is related to the material used for the oil seal: the material is nitrile rubber (-40~120°C), Aggreko rubber (ACM) -30~180°C, fluorine rubber (FPM) -25~300°C.

Aspects to consider when selecting oil seals
Choose a seal that has the appropriate dimension needed for your application. The seal should properly fit the space between the stationary and rotating parts.
