Assembly technology of round head needle

The design of locating pin is a kind of mechanical equipment manufacturing with high precision but easy to destroy. Cylindrical roller bearing can be maintained by mechanical seal of cylindrical roller bearing box or other ways. The application of this kind of sealing component occupies a lot of indoor space, which is harmful to the application design of commodities. Therefore, we slowly moved the sealing equipment to the locating pin shaft, and gradually improved. Nowadays, the cylindrical roller bearing with seal cover and seal ring has been widely used. The cylindrical roller bearing with seal structure needs to be continuously improved and many materials have been improved. Today, the assembly line of stainless steel plate cylindrical roller bearing is the key point of mesh weaving.

The key application of stainless steel plate cylindrical roller bearing with sealing equipment is the transmission shaft and hub shaft of special tools for road transportation such as railway vehicles and automobiles. The sealing equipment of the stainless steel plate cylindrical roller bearing has multiple structures and different characteristics for different application places.

When assembling stainless steel bearings on the assembly line, in addition to the regulation of grease injection quantity, the regulation of sealing packaging is also strict. In general, the sealing property of stainless steel plate locating pin installation often includes rubber products with steel frame, and it can be divided into categories and external sealing property. The external sealing property cooperates with the influence of external objects, and the internal sealing property cooperates with the auxiliary parts of inner cluster or inner hole. And the stainless steel plate cylindrical roller bearing generally has a long application time and is free of inspection and repair. In addition to the requirement that all relevant parts should meet the standard, the excellent assembly line quality is the key element that endangers the sealing equipment.

The sealing equipment of stainless steel bearing is also used in many different places, such as the stainless steel plate cylindrical roller bearing of the sealing extruder, that is to say, the sealing equipment is added on both sides of the double and four row cylindrical roller bearings. This kind of sealing equipment can be used independently, and can be clamped together with the stainless steel plate cylindrical roller bearing for precise positioning and replacement.
