How to avoid incorrect selection of hydraulic steering unit?

Avoid misselecting a hydraulic steering unit. A serial number like "101S" may represent a series, and specific parameters can vary between manufacturers, or even within the same manufacturer over time. Misselecting a model incorrectly can not only lead to steering failure but also serious safety incidents. The most dangerous approach is to simply order a new steering gear with the same name simply because it's engraved with "101S." While the correct approach is to use this as a clue, be sure to verify all key parameters listed below.

How To Choose A Piston Hydraulic Motor: A Comprehensive Guide

Selecting a piston hydraulic motor is a critical decision that directly impacts the performance, reliability, and longevity of hydraulic systems in various industries, from manufacturing to heavy machinery. Unlike orbital motors, piston motors excel in high-pressure, high-torque applications due to their robust design and precise engineering. However, a poor choice can lead to inefficiencies, premature wear, or system failures. This guide outlines a systematic approach to selecting the right piston hydraulic motor, covering fundamental principles, key technical parameters, and critical evaluation dimensions.
