Product Description
Product Overview
This product is a cotter pin compliant with GB/T 91 standard, with a nominal specification of 5×50. It is manufactured from carbon steel material and its surface is treated with Dacromet process. The product achieves reliable mechanical locking through bending the tail, and it is a key anti-loosening component that provides absolute safety guarantee for connectors in vibrating environments.
Core Advantages
-
Absolute Mechanical Anti-Loosening: A permanent mechanical lock is formed after the tail is bent, ensuring absolutely reliable anti-loosening effect.
-
Excellent Corrosion Resistance: The Dacromet coating provides superior anti-corrosion protection, and its salt spray resistance is far better than ordinary electroplating.
-
Convenient and Flexible Installation: Installation and disassembly can be completed without special tools, making it easy to use.
-
High-Toughness Base Material: High-quality carbon steel ensures good toughness, and it is not easy to break when bent.
Applicable Industries
-
Automotive and Transportation: Shaft end fixation of commercial vehicle chassis suspension and steering tie rods, as well as pin locking of truck compartment rails and construction machinery.
-
Heavy and General Machinery: Anti-falling and articulated connection of moving parts such as agricultural machinery, mining equipment, transmission system connecting rods and shaft parts.
-
Industrial Automation and Transmission: Reliable locking of core moving parts such as industrial robot joints, conveyor line roller shafts, and pneumatic/hydraulic cylinder trunnions.
-
New Energy and Power Facilities: Connection of maintenance ladders and guardrails outside the nacelle of wind turbines, as well as pin fixation of substation disconnectors and circuit breaker operating mechanisms.
-
Petrochemical and Outdoor Facilities: Safety pins for valve actuators, pipe rack supports, offshore platform guardrails and other outdoor or harsh environments that require high corrosion resistance.
-
Rail Transit and Vehicle Manufacturing: Detachable pin connection of key parts such as railway freight car bogies, door pedal mechanisms and braking system levers.
-
Construction and Steel Structure: Shear resistance and anti-loosening of pins at detachable steel structure bridges, large scaffolding, and lifting points of construction platforms.
Warm Tips
-
During installation, please bend the longer leg of the pin backward to ensure that the bending arc is natural and smooth to avoid stress concentration.
-
The Dacromet coating has a silver-gray matte surface; please avoid scratching it with sharp tools to maintain the best anti-corrosion effect.
