Optigear BM is formulated with Castrol&rsquo;s Microflux Trans (MFT) Plastic Deformation (PD) additive. MFT PD helps improve performance when operating temperature and loads reach a certain level of activation energy, by enabling the microsmoothing of surface roughness without increasing wear. The smoothed surface delivers optimum wear protection and an extremely low coefficient of friction, especially in applications which experience extreme pressure, shock loads, vibrations or low speeds. MFT PD helps to protect against scuffing and shock loading, while maintaining a high load carrying capacity, and can help prevent the progression of micro-pitting in pre-damaged gears. Specific grades within the Optigear BM range meet the requirements of DIN 51517 part 3 CLP and the requirements of a wide range of industrial bodies and equipment manufacturers. Optigear BM 68 and BM 220 are also classified as CGLP oils (DIN 51502). &lt;\/p&gt;\n&lt;\/div&gt;&lt;\/div&gt;\n&lt;\/div&gt;\n</p><h3>Caracter\u00edsticas t\u00edpicas&lt;\/h3&gt;\n<div>\n<table>\n<colgroup>\n<col span='\"1\"'>\n<col span='\"2\"'>\n<col span='\"2\"'>&lt;\/colgroup&gt;\n</colgroup><thead>\n<tr>\n<td>Especificaciones del producto:&lt;\/td&gt;\n</td><td>&lt;\/td&gt;\n</td><td>CASTROL Optigear BM 680&lt;\/td&gt;\n&lt;\/tr&gt;\n&lt;\/thead&gt;\n</td></tr></thead><tbody>\n<tr>\n<td>ruborizarse&lt;\/td&gt;\n</td><td>visual&lt;\/td&gt;\n</td><td>Marr\u00f3n&lt;\/td&gt;\n&lt;\/tr&gt;\n</td></tr><tr>\n<td>ISO Viscosity Group&lt;\/td&gt;\n</td><td>-&lt;\/td&gt;\n</td><td>680&lt;\/td&gt;\n&lt;\/tr&gt;\n</td></tr><tr>\n<td>Densidad a 15\u00b0C \/ 59\u00b0F\u00a0kg\/m\u00b3&lt;\/td&gt;\n</td><td>ISO 12185 \/ ASTM<br> D4052&lt;\/td&gt;\n</td><td>920&lt;\/td&gt;\n&lt;\/tr&gt;\n</td></tr><tr>\n<td>Viscosidad cinem\u00e1tica a 40\u00b0C \/ 104\u00b0F mm\u00b2\/s&lt;\/td&gt;\n</td><td>ISO 3104 \/ ASTM D445&lt;\/td&gt;\n</td><td>680&lt;\/td&gt;\n&lt;\/tr&gt;\n</td></tr><tr>\n<td>Viscosidad cinem\u00e1tica a 100\u00b0C \/ 212\u00b0F mm\u00b2\/s&lt;\/td&gt;\n</td><td>ISO 3104 \/ ASTM D445&lt;\/td&gt;\n</td><td>38.3&lt;\/td&gt;\n&lt;\/tr&gt;\n</td></tr><tr>\n<td>\u00cdndice de viscosidad&lt;\/td&gt;\n</td><td>ISO 2909 \/ ASTM D2270&lt;\/td&gt;\n</td><td>93&lt;\/td&gt;\n&lt;\/tr&gt;\n</td></tr><tr>\n<td>Punto de inflamaci\u00f3n: m\u00e9todo de copa abierta\u00a0\u00b0C\/\u00b0F&lt;\/td&gt;\n</td><td>ISO 2592 \/ ASTM D92&lt;\/td&gt;\n</td><td>245\/<br> 473&lt;\/td&gt;\n&lt;\/tr&gt;\n</td></tr><tr>\n<td>Punto de vertido \u00baC\/\u00b0F&lt;\/td&gt;\n</td><td>ISO 3016 \/ ASTM D97&lt;\/td&gt;\n</td><td>&nbsp;-9\/16&lt;\/td&gt;\n&lt;\/tr&gt;\n</td></tr><tr>\n<td>Copper corrosion (3 hrs@100&deg;C\/<br> 212&deg;F)&nbsp;Rating&lt;\/td&gt;\n</td><td>ISO 2160 \/ ASTM D130&lt;\/td&gt;\n</td><td>1&lt;\/td&gt;\n&lt;\/tr&gt;\n</td></tr><tr>\n<td>Rust test &ndash; distilled water (24 hrs)&lt;\/td&gt;\n</td><td>ISO 7120 \/ ASTM D665A&lt;\/td&gt;\n</td><td>escamote&lt;\/td&gt;\n&lt;\/tr&gt;\n</td></tr><tr>\n<td>Prueba de \u00f3xido \u2013 agua de mar sint\u00e9tica (24 horas)&lt;\/td&gt;\n</td><td>ISO 7120 \/ ASTM D665B&lt;\/td&gt;\n</td><td>escamote&lt;\/td&gt;\n&lt;\/tr&gt;\n</td></tr><tr>\n<td>FZG Gear Scuffing test &ndash; A\/8.3\/90&nbsp;Failure Load Stage&lt;\/td&gt;\n</td><td>ISO 14635-1&lt;\/td&gt;\n</td><td>&nbsp;&gt;12&lt;\/td&gt;\n&lt;\/tr&gt;\n</td></tr><tr>\n<td>FZG Micropitting tests @ 60&deg;C\/140&deg;F<br> and 90&deg;C\/194&deg;F&nbsp;Failure Load<br> Stage,<br> Micropitting Rating&lt;\/td&gt;\n</td><td>FVA 54-7&lt;\/td&gt;\n</td><td>&lt;\/td&gt;\n&lt;\/tr&gt;\n</td></tr><tr>\n<td>FE8 Bearing Wear Test<br> (F.562831.01-7.5\/80-80)&nbsp;Roller Wear, mg&lt;\/td&gt;\n</td><td>DIN 51819-3&lt;\/td&gt;\n</td><td>&lt;\/td&gt;\n&lt;\/tr&gt;\n&lt;\/tbody&gt;\n&lt;\/table&gt;&lt;\/div&gt;\n<p>&nbsp;&lt;\/p&gt;\n&lt;\/div&gt;\n</p><h3>informaci\u00f3n adicional&lt;\/h3&gt;\n</h3><p>Miscible and compatible with most mineral oil based gear oils.
