What is the function of a dowel pin in mechanical assemblies?

Dowel pins are precision alignment components used to accurately position and secure machine parts, ensuring correct assembly, reducing wear, and enhancing stability. They help maintain dimensional accuracy in fixtures, molds, and mechanical assemblies.

What is the recommended hole tolerance for installing a DP/m6 dowel pin?

For a press-fit, the recommended hole tolerance is H7, ensuring a secure and precise fit.

Can these dowel pins be reused after removal?

Dowel pins are typically not designed for frequent reuse, as removal can cause surface damage or size variation, affecting fit accuracy. However, slip-fit applications allow for reusability.

Why is hardened steel preferred for dowel pins?

Hardened steel dowel pins offer: ✔ High surface hardness (HRC58-62) for exceptional wear resistance. ✔ Superior shear strength, making them suitable for load-bearing alignment applications. ✔ Dimensional stability, reducing the risk of deformation over time.

Are DP/m6 dowel pins suitable for rotating applications?

No, dowel pins are primarily used for alignment and positioning.
