# Parallel shaft gearboxes and gearmotors

Posted by [Marketing Varvel](https://marketing.varvel.com/blog/en/author/marketing-varvel) on Nov 15, 2021 10:25:00 AM

Like all **gearboxes and gearmotors**, the **parallel shaft** units are fundamental assets for the most diverse **applications in the mechanical industry**. Compact in size yet powerful, they work to **convey the motion of a motor to the machine** on which they are fitted, reducing the speed and adapting it to specific functional requirements.

The great **flexibility and versatility of use** makes **parallel shaft gearboxes and gearmotors** ideal for applications in various industries, and virtually wherever **movement is needed**. Typical examples include **intralogistics** and **constructions**.

All details of the components are carefully sized to allow **either horizontal or vertical positioning**. The **compact footprint** makes the units perfect for construction applications in **small housings** that are in very high demand in **today's industrial processes**.

However, it is important to note that a **smaller footprint** does not mean less power. On the contrary, **parallel shaft gearboxes and gearmotors** are **strong, dynamic, and very reliable mechanical transmissions** that can be an **excellent investment for companies** because of their inherent ability to make operations more efficient and their very simple maintenance requirements.
