Features
High Dimensional Accuracy
Manufactured to tight dimensional tolerances (often ±0.01–0.05 mm) for accurate part alignment in mechanical assemblies.
Durable Materials
Can be made from carbon steel for higher strength, or stainless steel for excellent corrosion resistance; all the materials can offer long service life.
Smooth Surface Finish
High-quality machining or grinding results in consistent surface finish, facilitating press-fit or slip-fit installation.
Applications
Positioning
Ensures precise alignment by limiting part translation or rotation within a plane; widely used in machine tools and precision equipment to maintain motion accuracy and prevent machining errors.
Connection
Acts as an auxiliary anti-rotation element when bolts alone are insufficient; commonly installed in pipe flanges, motor end covers, and housings to stabilize connections under vibration.
Torque Transmission
Transfers small torque in compact assemblies through interference-fit friction or shear; typical in toy motors, miniature pumps, and light-duty mechanical couplings.
Safety Shear Protection
Functions as a sacrificial component that shears under overload to protect critical equipment; used in belt conveyors where pin failure prevents motor and drum damage during jams.
