loebke fasteners Germany loebke models loebke prices

loebke fasteners are installed in shaft grooves or bore grooves of machines and equipment, serving to prevent lateral movement of components on the shaft or in the bore. Fixation of shaft components is divided into axial fixation and circumferential fixation. Methods for axial fixation include: fixation by shaft shoulders or collars, fixation by end rings or conical surfaces, fixation by sleeves, fixation by round nuts, and fixation by elastic retaining rings. Retaining rings primarily serve for axial fixation, with conical surface plus retaining ring fixation offering higher centering accuracy. The retaining ring of a rolling bearing acts as a movable shoulder for guiding rollers, facilitating installation. Retaining ring structures include flat retaining rings, angled retaining rings, and centering rings. Fastener retaining rings are a type of mechanical component widely used for fastening connections. Various types of fastener retaining rings can be seen on all kinds of machinery, instruments, meters, and supplies. They are characterized by a wide variety of specifications and a high degree of standardization, serialization, and generalization.

loebke fastener performance

Gears use shaft shoulders and retaining rings; pulleys are fixed using shaft shoulders and retaining rings. When using retaining ring fixation, if the distance between retaining rings on the shaft is large, round nuts may be used. The length of the shaft section where the component is installed should be made 2~9mm shorter than the hub width of the component to ensure that the sleeve, nut, and retaining ring press tightly against the end face of the component's shaft section. The purpose of circumferential fixation of shaft retaining rings is to transmit torque and prevent relative rotation between the component and the shaft. To improve the performance of rubber sealing products and prevent damage from extrusion under high pressure, some rubber sealing products (such as: O-rings, Y-rings, V-rings, drum-shaped rings, etc.) require additional retaining rings, support rings, and compression rings to enhance their pressure-bearing capacity and ensure sealing performance. Materials mainly used for making retaining rings for sealing products include polytetrafluoroethylene (PTFE), nylon, and polyoxymethylene (POM).

loebke fastener classification

Flat retaining ring: A separable, basically flat washer whose inner or outer part serves as a shoulder for the outer or inner ring of a radial cylindrical roller bearing. Angled retaining ring: A separable ring with an "L"-shaped cross-section, whose outer part serves as the inner shoulder for radial roller bearings. Centering ring: A separable ring in double-row or multi-row roller bearings, used to separate and guide the rows of rollers. To ensure grinding precision across the entire shaft diameter, narrow shoulders parallel to the rolling direction and protruding from the raceway surface are used to support and guide the rolling elements, keeping them within the bearing. Retaining rings include: taper pin locking retaining rings, screw locking retaining rings, screw locking retaining rings with locking washers, wire retaining rings, hole-type elastic retaining rings - Type A, hole-type elastic retaining rings - Type B, shaft-type elastic retaining rings - Type A, shaft-type elastic retaining rings - Type B, screw-fastened shaft end retaining rings, bolt-fastened shaft end retaining rings, hole-type wire retaining rings, shaft-type wire retaining rings, etc.

loebke fastener applications

The development of the mechanical industry has also raised higher requirements for fastening products. High-end fasteners (high-temperature, special shapes, titanium-plastic composites, special performance, etc.) are in short supply and still rely on imports. Retaining rings are applied in various machinery, equipment, vehicles, ships, railways, bridges, construction, structural assemblies, valves, instruments, various lock core components, needle roller bearings, pulleys, connectors, tools, and supplies, as well as quick couplings and other mechanical assemblies. Various types of fastener retaining rings can be seen everywhere. Therefore, some people refer to fasteners that already have national standards as standard fasteners, or simply as standard parts. Retaining rings can also position other components; relying on their own elasticity for easy assembly and disassembly, they are a type of mechanical component widely used for fastening connections.
