Another key benefit of using wedge bolts is their high load-bearing capacity. The expansion design of the bolt allows it to distribute the load evenly across the connected components, reducing the risk of material failure or structural damage. This makes them ideal for applications where high tension and shear forces are present, such as in seismic retrofitting, bridge construction, or steel frame assemblies
J-bolts are another type of foundation bolt that features a J-shaped end for securing objects to concrete or masonry surfaces. These bolts are commonly used for securing equipment, machinery, or structural components to a foundation
The skeleton oil seal structure consists of three parts: the oil seal body, the reinforced skeleton and the self-tightening coil spring. The sealing body is divided into bottom, waist frame oil seal structure diagram, cutting edge and sealing lip according to different parts. Generally, the inner diameter of the skeleton oil seal in the free state is smaller than the shaft diameter, that is, it has a certain interference. Therefore, after the oil seal is installed on the oil seal seat and the shaft, the pressure of the oil seal edge and the contraction force of the self-tightening coil spring will produce a certain radial tightening force on the shaft. After a period of operation, the pressure will rapidly decrease or even disappear. , Therefore, adding a spring can compensate for the self-tightening force of the oil seal at any time.

- The material selection for these seals is meticulous, prioritizing resistance to wear, temperature fluctuations, and chemical degradation. They must withstand the vagaries of their operating conditions, whether subzero temperatures or scorching heat, without compromising their integrity. Moreover, the double lip oil seal's design allows for some degree of self-lubrication, further enhancing its durability and reducing friction during operation Moreover, the double lip oil seal's design allows for some degree of self-lubrication, further enhancing its durability and reducing friction during operation

To install an oil seal properly, the shaft must be undamaged. This is so the oil seal can do its job properly on the one hand, and to prevent it from being damaged during fitting on the other. In addition, it is very important to lubricate the shaft, the sealing lip and the bore with plenty of grease. This will allow the oil seal to slide more easily over the shaft and prevent dry running after the first rotation. The oil seal may also come into contact with the keyway, thread or other grooves when sliding over the shaft. By taping or covering the shaft at the location of these irregularities with oil-soaked paper, the oil seal can be mounted without damage to the sealing lip.
Amongst the several applications of oil seals, these are the most common three applications – o-rings, spring seals, and lip seals.
