Elastomer Sealing Technology in Hydraulic Systems

A Practical Reliability Guide to Materials, Failure Mechanisms, and Engineering ValidationFluid power systems—hydraulics and pneumatics—are the “muscle and nerves” of modern industry. They transmit energy through pressurized fluid in a closed circuit, and seals are the barrier that keeps that circui

Hydraulic Steering Units Explained: Open Center, Closed Center, Load Sensing, Reaction & Non-Reaction

Hydraulic steering units—often called hydraulic steering control units (SCU), hydrostatic steering units, or orbital steering units (Orbitrol‑type)—are the “command center” of a hydraulic steering system. They turn a small steering wheel input into a precisely metered oil flow that moves a steering

Hydraulic Oil Foaming: Causes, Effects, And Solutions

Hydraulic oil foaming is a common issue in industrial hydraulic systems. Many engineers and maintenance professionals have noticed that even after filtering out contaminants, water, and entrained air, their hydraulic fluid can still produce excessive foam. This foaming not only looks concerning but

How To Select The Right Hydraulic Hoses And Fittings for Industrial Systems

Hydraulic hoses and fittings are the lifelines of industrial hydraulic systems, enabling the transfer of high-pressure fluid that powers heavy machinery. In Belt and Road Initiative countries – spanning Russian-speaking regions to Spanish-speaking nations – these components are critical in construct

Managing High Hydraulic Oil Temperature in Tight Spaces

Hydraulic systems rely on properly cooled oil for smooth operation. Ideally, fluid stays around 30–60 °C; once oil climbs above ~65–80 °C, viscosity drops, lubrication fails, and parts can heat, seize or wear out. High oil temperature also wastes power as heat and often leads to component damage. W

Hydraulic Motor with Brake: Internal vs External Brake Systems

Hydraulic systems often require a brake to safely stop and hold loads. Hydraulic motors can be equipped with an internal (integrated) brake or use a separate external brake system. Blince offers both options on its motors. For example, the BMR-BK01 series are Braked hydraulic motors with built-in sp

Hydraulic Unloading Valve Vs Relief Valve: Working Principles, Differences And Applications

Hydraulic systems use pressure-control valves for efficiency and safety. An unloading valve (left) and a relief valve (right) may look similar, but their roles differ. An unloading valve automatically diverts the pump’s flow back to the reservoir during idle or low-demand phases, significantly savin

Hydraulic Valve Center Positions: O, Y, H, M

Directional control valves route hydraulic fluid via an internal spool. When the spool is centered (neutral), different center positions (O, H, Y, M) determine which ports (pressure, tank, actuator ports) are connected or blocked. The four common center types are:
