emil hembeck fasteners Germany emil hembeck models emil hembeck prices

emil hembeck fasteners are made by bonding and vulcanizing a rubber ring and a metal ring into a single unit. They are sealing rings used to seal threaded and flange connections. The ring consists of a metal ring and a rubber gasket. The metal ring is treated for rust prevention, and the rubber ring is typically made of oil-resistant nitrile rubber or fluororubber. Combined gaskets are available in metric and imperial sizes, with standards specifying the combination of metal and rubber. Combined sealing washers are used for sealing threaded pipe fittings and plugs. They are generally used with bite-type pipe fittings to seal oil ports, primarily for static face sealing at threaded connections of hydraulic valve pipe fittings. They are suitable for static face sealing at British and American standard imperial thread connections and French and German standard metric thread connections.

emil hembeck fastener applications

A type of fastener shaped like a flat annular ring. Placed between the bearing surface of a bolt, screw, or nut and the surface of the connected part, it increases the contact surface area, reduces pressure per unit area, and protects the surface of the connected part from damage. Another type, elastic washers, also prevents nuts from loosening. Washers and retaining rings are elastic pads or anti-loosening washers that prevent bolts from loosening. The working principle of anti-loosening washers is very simple. They consist of two washers. The outer side has radial convex patterns, while the inner side has inclined teeth. During assembly, the inner inclined tooth faces oppose each other, and the outer radial convex patterns engage with the contact surfaces at both ends. When the connected parts vibrate and the bolt tends to loosen, only relative sliding between the inner inclined tooth faces of the two washers is allowed, generating lifting tension, thereby achieving 108% locking.

Also used in faucets (valves) to cut off the flow of liquids or gases. Rubber or silicone gaskets can also be used to reduce fan vibration. Typically, the outer diameter of a washer is about twice its inner diameter. Nitrile rubber is the most commonly selected material for rubber gaskets due to its highest cost-performance ratio. The use of rubber gaskets is generally found in more advanced fields, such as aerospace and rocketry. However, their performance is excellent and can surpass many metal materials. Various types of fasteners can be seen on all kinds of machinery, equipment, vehicles, ships, railways, bridges, buildings, structures, tools, instruments, meters, and supplies. Their characteristics include a wide variety of specifications, diverse performance and applications, and a high degree of standardization, serialization, and generalization. Therefore, some people refer to fasteners that already have national standards as standard fasteners, or simply as standard parts.

emil hembeck fastener features

Ensures that the clamping force of the connection is maintained even under strong vibration, superior to fasteners that rely on friction for self-locking; prevents bolt loosening caused by vibration, eliminating related problems caused by loose fasteners; no special installation work is required, easy to install and disassemble; temperature changes do not cause loosening of the connection; durable; reusable. Improves the anti-loosening level through structural anti-loosening methods, offering higher safety performance; prevents loosening caused by vibration and dynamic loads; Easy installation, does not affect changes in installation drawings, and easy disassembly; loosening torque is greater than tightening torque; Locking effect is not affected by lubrication, and increased lubrication improves the anti-loosening effect; has the same temperature characteristics as standard bolts and nuts; can be reused a limited number of times.
