The 101S‑1x 2, 3 & 4 Series Hydraulic Steering Control Units (SCU) are advanced hydraulic steering modules designed to provide precise steering control, smooth maneuverability, and exceptional safety in mobile equipment and off‑highway machinery. These units integrate key steering functions into a compact, modular assembly, enabling reliable performance in demanding working environments such as construction, agriculture, material handling, forestry, and mining equipment.

Note:L is the maximum length dimension of product.This dimension on some products may 2mm or 4mm shorter.

🔹 Product Overview

Hydraulic Steering Control Units (SCUs) are central components in closed‑center, load‑sensing, or open‑center steering circuits. The 101S‑1x Series combines precision valves, feedback mechanisms, and flow control elements to translate operator steering input into controlled hydraulic flow for steering cylinders or orbit motors.

Available in multiple configurations (2‑Series, 3‑Series, 4‑Series), the 101S‑1x SCU family supports a wide range of flow capacities and steering requirements, making it suitable for small loaders, forklifts, graders, tractors, and larger articulated vehicles.
