of a rotating shaft perpendicular to its axis of rotation, radiating outward from the centre like the spokes of a wheel. The word &#8220;radial&#8221; covers any direction that points away from the shaft centreline, so it embraces both horizontal (side-to-side) and vertical (up-and-down) movement. It is the same quantity engineers call <a href=\"https:\/\/vibromera.eu\/ca\/glossary\/lateral-vibration\/\">vibraci\u00f3 lateral<\/a> or transverse vibration, and it is by far the most commonly measured and trended form of <a href=\"https:\/\/vibromera.eu\/ca\/glossary\/vibration\/\">vibration<\/a> in rotating machinery \u2014 the first number a reliability technician looks at, and the one most international standards are written around. In practice it is measured in two perpendicular directions at each bearing so that the shaft&#8217;s full path through space can be reconstructed.<\/p>\n<h2>1. Definition and Measurement Directions<\/h2>\n<p>Because a shaft can move in any direction within the plane perpendicular to its axis, a single sensor never tells the whole story. Two probes mounted 90\u00b0 apart at each bearing capture the complete radial picture, and their readings are usually reported separately as well as combined.<\/p>\n<h3>Vibraci\u00f3 radial horitzontal<\/h3>\n<p>Horizontal vibration is the side-to-side motion of the shaft:<\/p>\n<ul>\n<li>Perpendicular to the shaft axis and parallel to the floor.<\/li>\n<li>Often the most accessible measurement point on a horizontal machine.<\/li>\n<li>Reflects gravity, foundation-stiffness asymmetry, and horizontal forcing functions.<\/li>\n<li>The standard measurement orientation for most routine monitoring programmes.<\/li>\n<\/ul>\n<h3>Vibraci\u00f3 radial vertical<\/h3>\n<p>Vertical vibration is the up-and-down motion of the shaft:<\/p>\n<ul>\n<li>Perpendicular to the shaft axis and perpendicular to the floor.<\/li>\n<li>Directly influenced by gravity and the static weight of the rotor.<\/li>\n<li>Frequently higher in amplitude than horizontal because rotor weight creates asymmetric support stiffness.<\/li>\n<li>Critical for diagnosing vertically oriented machines such as vertical pumps and motors, where &#8220;horizontal&#8221; and &#8220;vertical&#8221; lose their usual meaning and the two radial axes are simply orthogonal.<\/li>\n<\/ul>\n<h3>Vibraci\u00f3 radial global<\/h3>\n<p>The two directional readings are sometimes combined into a single vector total:<\/p>\n<blockquote><p>Radial Total = \u221a(Horizontal\u00b2 + Vertical\u00b2)<\/p><\/blockquote>\n<ul>\n<li>Can be a convenient in-house metric for trending, condensing both directions into one number.<\/li>\n<li><strong>Not a standard severity number:<\/strong> ISO 20816 (like ISO 10816 before it) evaluates the <em>higher<\/em> of the two individually measured orthogonal radial values against its zone boundaries \u2014 do not compare this combined total directly to ISO 20816 limits, or use it for ISO-based alarm setting, unless the standard or procedure you follow explicitly defines such a combined metric.<\/li>\n<li>Because the two axes rarely peak at the same instant, the orbit the shaft traces is usually an ellipse rather than a circle \u2014 a fact that becomes important in orbit analysis.<\/li>\n<\/ul>\n<h2>2. Primary Causes of Radial Vibration<\/h2>\n<p>Radial vibration is produced by any force acting perpendicular to the shaft axis. Identifying the dominant frequency is the heart of diagnosis, because each fault leaves a characteristic signature.<\/p>\n<h3>1. Unbalance (the Dominant Cause)<\/h3>\n<p><a href=\"https:\/\/vibromera.eu\/ca\/glossary\/unbalance\/\">Unbalance<\/a> is the single most common source of radial vibration in rotating equipment:<\/p>\n<ul>\n<li>It creates a <a href=\"https:\/\/vibromera.eu\/ca\/glossary\/centrifugal-force\/\">centrifugal force<\/a> that rotates with the shaft, appearing at <a href=\"https:\/\/vibromera.eu\/ca\/glossary\/running-speed\/\">velocitat de funcionament (1X)<\/a>.<\/li>\n<li>The force grows with the unbalance mass, its radius, and \u2014 critically \u2014 the square of speed, so a small heavy spot becomes a serious problem as RPM rises.<\/li>\n<li>It produces a broadly circular or elliptical <a href=\"https:\/\/vibromera.eu\/ca\/glossary\/orbit\/\">\u00f2rbita de l'eix<\/a>.<\/li>\n<li>It is correctable through <a href=\"https:\/\/vibromera.eu\/ca\/glossary\/balancing\/\">equilibri<\/a>, the only one of these faults that can usually be fixed without replacing parts.<\/li>\n<\/ul>\n<h3>2. Desalineaci\u00f3<\/h3>\n<p><a href=\"https:\/\/vibromera.eu\/ca\/glossary\/misalignment\/\">desalineaci\u00f3 de l'eix<\/a> between coupled machines generates both radial and <a href=\"https:\/\/vibromera.eu\/ca\/glossary\/axial-vibration\/\">vibraci\u00f3 axial<\/a>:<\/p>\n<ul>\n<li>It shows predominantly as 2X (twice-per-revolution) radial vibration.<\/li>\n<li>It also generates 1X, 3X, and higher <a href=\"https:\/\/vibromera.eu\/ca\/glossary\/harmonics\/\">harmonics<\/a>.<\/li>\n<li>High axial vibration accompanying the radial signal is a strong clue.<\/li>\n<li>The <a href=\"https:\/\/vibromera.eu\/ca\/glossary\/phase\/\">phase<\/a> relationship between the two bearings tells you whether the misalignment is angular, parallel (offset), or both.<\/li>\n<\/ul>\n<h3>3. Defectes mec\u00e0nics<\/h3>\n<p>Several mechanical problems produce distinctive radial patterns:<\/p>\n<ul>\n<li><strong><a href=\"https:\/\/vibromera.eu\/ca\/glossary\/bearing-defects\/\">Defectes dels rodaments<\/a>:<\/strong> high-frequency impacts at the <a href=\"https:\/\/vibromera.eu\/ca\/glossary\/bearing-fault-frequencies\/\">bearing fault frequencies<\/a>.<\/li>\n<li><strong>Bent or bowed shaft:<\/strong> 1X vibration that resembles unbalance but is present even at slow roll \u2014 see <a href=\"https:\/\/vibromera.eu\/ca\/glossary\/shaft-bow\/\">shaft bow<\/a>.<\/li>\n<li><strong><a href=\"https:\/\/vibromera.eu\/ca\/glossary\/looseness\/\">Afluixament<\/a>:<\/strong> multiple harmonics (1X, 2X, 3X and beyond) with non-linear, often directional, behaviour.<\/li>\n<li><strong>Fissures:<\/strong> 1X and 2X vibration that changes during start-up and shutdown \u2014 a hallmark of a <a href=\"https:\/\/vibromera.eu\/ca\/glossary\/cracked-rotor\/\">rotor esquerdat<\/a>.<\/li>\n<li><strong>Fregaments:<\/strong> a mix of sub-synchronous and synchronous components, characteristic of <a href=\"https:\/\/vibromera.eu\/ca\/glossary\/rotor-rub\/\">rotor rub<\/a>.<\/li>\n<\/ul>\n<h3>4. Forces aerodin\u00e0miques i hidr\u00e0uliques<\/h3>\n<p>Process forces inside pumps, fans, and compressors apply radial forcing of their own:<\/p>\n<ul>\n<li><a href=\"https:\/\/vibromera.eu\/ca\/glossary\/blade-passing-frequency\/\">Freq\u00fc\u00e8ncia de pas de pales<\/a> (number of blades \u00d7 RPM).<\/li>\n<li>Hydraulic unbalance arising from asymmetric flow.<\/li>\n<li>Vortex shedding and flow turbulence.<\/li>\n<li>Recirculation and off-design operation, including <a href=\"https:\/\/vibromera.eu\/ca\/glossary\/cavitation\/\">cavitaci\u00f3<\/a> in pumps.<\/li>\n<\/ul>\n<h3>5. Condicions de resson\u00e0ncia<\/h3>\n<p>When the machine operates near a <a href=\"https:\/\/vibromera.eu\/ca\/glossary\/critical-speed\/\">critical speed<\/a>, la vibraci\u00f3 radial s'amplifica de manera dr\u00e0stica:<\/p>\n<ul>\n<li>A natural frequency coincides with a forcing frequency, the classic condition for <a href=\"https:\/\/vibromera.eu\/ca\/glossary\/resonance\/\">resonance<\/a>.<\/li>\n<li>Amplitude is then limited only by the system&#8217;s <a href=\"https:\/\/vibromera.eu\/ca\/glossary\/damping\/\">damping<\/a>.<\/li>\n<li>Levels can climb toward catastrophic values within a narrow speed band.<\/li>\n<li>Design therefore requires adequate separation margins between operating speed and critical speeds.<\/li>\n<\/ul>\n<h2>3. Measurement Standards and Parameters<\/h2>\n<h3>Unitats de mesura<\/h3>\n<p>Radial vibration can be expressed in three related parameters, each suited to a different frequency range:<\/p>\n<ul>\n<li><strong><a href=\"https:\/\/vibromera.eu\/ca\/glossary\/displacement\/\">Despla\u00e7ament<\/a>:<\/strong> the actual distance moved (micrometres \u00b5m, or mils). Used for low-speed machinery and <a href=\"https:\/\/vibromera.eu\/ca\/glossary\/proximity-probe\/\">proximity-probe<\/a> shaft measurements.<\/li>\n<li><strong><a href=\"https:\/\/vibromera.eu\/ca\/glossary\/velocity\/\">Velocitat<\/a>:<\/strong> the rate of change of displacement (mm\/s, in\/s).
