Application scenario

Rail Transit and Vehicle Chassis Structure

Our Stainless Steel DIN 25201 Double Stack Lock Washer is suitable for vehicle chassis, track supporting equipment, and traffic facilities tightening scenarios. It can withstand vehicle driving vibrations, continuous impacts, and dynamic loads, eliminating bolt loosening caused by changing road conditions and external forces, and enhancing the safety coefficient of traffic facilities.

Wind Power, Hydraulic and Power Equipment

Suitable for wind power equipment, hydraulic units, and power transmission devices with long-term continuous operation. For continuous vibration, alternating torque, and all-weather operation environments, it provides long-term stable anti-loosening protection, reducing the frequency of equipment shutdown and maintenance.

Engineering Steel Structures and Large-scale Infrastructure

Used for bolt locking of steel structure frames, engineering supports, and outdoor large fixed structures, it is compatible with open-air, heavy-load, and long-term service infrastructure conditions. It has excellent anti-aging and anti-fatigue performance, ensuring the long-term stability of engineering structures.

5 Precision Automation Equipment

Suitable for high-precision assembly of automated production lines, precision fixtures, and intelligent equipment. By relying on uniform force application and zero-displacement locking advantages, it avoids equipment accuracy deviation caused by slight loosening, ensuring the assembly benchmark and operation accuracy of precision equipment.

Product Parameter

Key Performance Merits & Practical Engineering Deployment

1. Innovative double-layer tooth interlocking self-locking principle completely abandons the limitation of traditional elastic anti-loosening. It uses structural friction to resist vibration and impact, achieving zero loosening under high-frequency vibration conditions where ordinary spring washers fail.

2. Bidirectional symmetrical tooth surface design provides ultra-high locking force, which can withstand strong alternating load and mechanical impact, effectively solving thread loosening and connection failure of key equipment parts during long-term operation.

3. High-hardness tooth surface and integral toughening treatment ensure strong wear resistance and fatigue resistance. No tooth surface wear or structural failure occurs after millions of vibration cycles, maintaining permanent locking stability.

4. Simple assembly and strong compatibility, no need for additional flat washers or anti-loosening glue. It integrates pressure bearing, surface protection and high-strength anti-loosening functions, saving assembly procedures and improving installation efficiency.

5. Diversified material grades adapt to high-end harsh environments, widely used in railway transportation, automotive engineering, wind power equipment, mechanical heavy industry, aerospace auxiliary facilities and other high-reliability required fields.

FAQ

Q1: What is the difference betweenstainless steel DIN 25201 Double Stack Lock Washer and ordinary DIN 127 spring washers?

A1: DIN 127 relies on elastic tension for anti-loosening, easy to fatigue and fail under strong vibration; DIN 25201 adopts double-tooth interlocking friction self-locking structure, with mechanical locking principle, no elastic fatigue, far stronger anti-vibration performance, suitable for heavy-duty and high-stability key connections.

Q2: Do I need to use flat washers with DIN 25201 double lock washers?

A2: Not required. The flat outer surface of DIN25201 can well protect the workpiece, and the internal tooth structure independently completes high-strength locking. It integrates protection and anti-loosening functions, simplifying the assembly combination.

Q3: Can DIN 25201 resist long-term strong vibration?

A3: Yes. It adopts physical structural locking rather than elastic locking. It will not produce fatigue failure under continuous vibration and impact, and is recognized as one of the most reliable passive anti-loosening washer solutions in the industry.

Q4: What core scenarios is DIN 25201 suitable for?

A4: It is specially used for key fastening parts that are prone to severe vibration and require zero loosening, such as rail transit equipment, new energy wind power structures, automobile chassis, heavy machinery, engineering equipment and precision vibration machinery.

Q5: Are customized special specifications supported?

A5: Yes. We support customizing special outer diameter, thickness, tooth surface hardness and super anti-corrosion coating to meet the anti-loosening and fastening requirements of special industrial equipment.
