Product Description
Dowel pin
●Product Introduction
The stainless steel cylindrical dowel pin, also known as a locating pin, stop pin, or pivot pin, is a fundamental mechanical fastening and locating component. Its main body is precision machined from high-quality stainless steel into a standard cylindrical geometry. Renowned for its exceptional corrosion resistance, high strength, precision, and long service life, this product is widely used in various mechanical equipment, jigs & fixtures, and precision instruments that require reliable positioning, motion limitation, connection, or prevention of component rotation. It is the ideal choice to replace ordinary steel pins in demanding environments, such as those with moisture, cleanliness requirements, or mild chemical exposure.
●Structural Features
Precision Location: Provides accurate relative positioning for two or more components by being inserted into matching holes, ensuring repeatable assembly accuracy.
Axial Limitation (Stopping): Its primary function is to restrict the axial movement of parts mounted on shafts (e.g., gears, bearings, pulleys), securing them in a fixed position.
Torque Transmission: In simple connections, it can serve as a key to transmit modest torque or prevent rotation.
Safety Protection: Acts as an overload protection element (shear pin). Under abnormal load conditions, the pin is designed to shear first, thereby safeguarding more expensive primary equipment.
Quick Connection & Pivoting: Can function as an axle for light-duty hinges or in connecting parts requiring quick engagement/disengagement
●Typical Applications
Precision Machinery & Automation Equipment: Used for precise location and axial limiting in robot joints, linear modules, conveyor mechanisms, and assembly fixtures.
◆Jigs, Fixtures & Molds: Locates workpieces in fixtures; secures plates and guide posts in molds, ensuring repeatable machining and production accuracy.
◆Food & Pharmaceutical Machinery: Widely used in equipment contacting products or in washdown environments due to stainless steel's hygiene, corrosion resistance, and cleanability.
◆Medical Devices & Instrumentation: Found in hospital beds, surgical instruments, analytical instruments, and other areas requiring high cleanliness, resistance to sterilization, and reliability.
◆Marine & Chemical Processing Equipment: Performs excellently in outdoor or industrial environments with moisture, high salinity, or chemical media, especially Grade 316 series pins.
◆Electronics & Semiconductor Manufacturing: Used in production equipment, test fixtures, and handling devices within cleanrooms to prevent contamination and rust.
◆General Industrial Maintenance & Replacement: Serves as a standard spare part to replace failed ordinary steel pins due to corrosion or wear, extending equipment lifespan.
