Customized Tungsten Carbide Button for High-Strength Dowel Pins

Purpose and Features:
The tungsten carbide dowel pin is a crucial component of the crankshaft, designed to withstand the forces transmitted by the connecting rod on the crankshaft. The crankshaft is a vital component in the engine, responsible for converting the forces transmitted by the connecting rod into output torque, thereby driving other accessories on the engine. The crankshaft is subjected to the combined effects of centrifugal force from rotating mass, periodic inertial forces from gases, and reciprocating inertial forces, necessitating sufficient strength and rigidity. The surface of the journal requires wear resistance, smoothness, and good balance.

Customized Production:
This tungsten carbide dowel pin is precision-customized and manufactured according to the customer's drawings from a manufacturer in Zhejiang. The dimensional specifications have a tolerance requirement of φ3.8(+0.02/+0)×φ0.2×7.8(±0.025)×R1.9. The appearance requires a mirror-polished surface finish with Ra0.4. The Tungsten carbide dowel pin has relatively small dimensions, and the tips on both sides must maintain a 90-degree vertical position.
