In addition to their versatility, double-ended bolts with nuts in the middle also offer the advantage of easy installation. The nut in the middle allows for quick and secure tightening of the bolts, making them ideal for applications where speed and efficiency are important. This can help save time and labor costs during the assembly process
Oil seals are one of the major contact type sealing devices.
• They prevent leakage of the lubricant or other sealed substance, and
• prevent entry of dust and foreign matter (dirt, water, metal powder, etc.) from outside.

(3) The oil seal with general pressure has poor pressure bearing capacity, and the oil seal will deform when the pressure is too large. In the case of excessive pressure, a pressure-resistant bearing ring or a reinforced pressure-resistant oil seal should be used.

These problems can be overcome through a better understanding of the types of sealing materials available, redefined selection procedures and the consistent application of sound replacement and maintenance practices.
When included, the garter spring applies pressure to the sealing lip against the shaft, ensuring a tight seal. The choice of material, like that of the case, largely depends on the environment of use.
