Customized Tungsten Carbide Button For High-Strength Dowel Pins

This customized tungsten carbide dowel pin serves as a critical crankshaft component engineered to withstand the substantial forces transmitted by connecting rods. As a vital engine component, the crankshaft converts connecting rod forces into output torque to drive engine accessories while enduring centrifugal forces, gas inertial forces, and reciprocating inertial forces.

Manufactured according to customer specifications with dimensional tolerance requirements of φ3.8(+0.02/+0)×φ0.2×7.8(±0.025)×R1.9. The product features a mirror-polished surface finish with Ra0.4 specification. Both tips maintain precise 90-degree vertical positioning despite the component's compact dimensions.

Due to the high density and compact size of tungsten carbide components, we employ specialized packaging to prevent transit damage. Products are secured in sturdy boxes with bubble wrap, foam, bubble bags, and cardboard as needed.
