German schnorr anti-loosening safety washers, special price, in stock

The German schnorr anti-loosening safety washer is a washer used between the connected parts and the nut to prevent bolt loosening.schnorr anti-loosening safety washerConsists of two washers, with radial cams on the outer side and inclined teeth on the inner side. The working principle is very simple: during assembly, the inner inclined tooth faces oppose each other, and the outer radial cam faces engage with the contact surfaces at both ends. When the connected parts are subjected to vibration, causing a tendency for the bolt to loosen, only relative sliding between the inner inclined tooth faces of the two washers is allowed, generating lifting tension to achieve the 100% locking effect. schnorr anti-loosening safety washers can be applied in all high-vibration environments.Original schnorr anti-loosening safety washers are developed based on the basic principle of disc springs, serving as a reliable and economical bolt locking device that resists the effects of vibration through secure fastening connections. This clever design combines the safety advantages of friction and mechanical locking. schnorr anti-loosening safety washers are widely used worldwide, from automotive engineering to machining, cement, and plant engineering. Additionally, safety washers can be used in lawn mowers, textile machines, machine tools, pneumatic drills, the steel industry, etc.

German schnorr anti-loosening safety washers: structure and features

Original German schnorr anti-loosening safety washers are in the form of disc springs, with a trapezoidal cross-section and serrations on both sides. The outer diameter matches the head diameters of pan head and hex socket head screws.schnorr anti-loosening safety washers are available in two versions:

1). Standard safety washers "S" type are suitable for sizes M1.6 to M36 and property classes up to 8.8bolts。

2). For property classes 8.8 and 10.9bolts, meaning higher preload is required, in which case the reinforced "VS" type safety washers should be used.

Due to the conical shape and helical gear transmission mechanism, optimal traction force is achieved in the maximum positive locking state.

schnorr anti-loosening safety washer advantages: 1). High vibration resistance due to reliable locking by the serrations. 2). Concentric force transmission and uniform axial load eliminate bending torque and deformation of the bolt. 3). The serration design prevents friction and damage to components during tightening. 4). Extremely high security against loss of clamping force and loosening. 5). Various materials and different finishes. 6). Closed-loop form results in high pre-tension while avoiding burst opening effects. 7). The development and design of the washers are based on screw geometry, tightening torque, and construction conditions.

Assembly requirements for German schnorr anti-loosening safety washers

schnorr anti-loosening washers are characterized by simple installation.

1). Simply place the two washers with their inner inclined tooth surfaces facing each other between the nut and the connected material;

2). After the nut is tightened, the outer radial cam surface of the anti-loosening washer engages with the contact surfaces at both ends, and the wedge angle of the inner inclined tooth surface is greater than the thread angle of the bolt;

3). When the bolt is elongated due to mechanical vibration, the nut tends to rotate and loosen. Since the friction on the outer radial cam surface of the anti-loosening washer is greater than the friction between the inner inclined tooth surfaces, only relative sliding between the inner inclined tooth surfaces is allowed in this state, thereby generating a certain lifting tension;

4). When the bolt contracts, the inclined tooth surfaces of the washer return the nut to its original position. Thus achieving 100% anti-loosening and locking effect;

5). The washers are suitable for relatively flat and smooth surfaces;

6). If the connected material is non-metallic, a metal plate can be fixed to the connected material, allowing the use of anti-loosening washers;

7). No torque wrench is required when installing anti-loosening washers;

8). Pneumatic tools may be used when installing or removing anti-loosening washers.
