We produce two right angle planetary gearbox series that share a product category but serve different applications: the EP300R<\/strong> and the NB300R<\/strong>. Both deliver coaxial planetary reduction with a bevel output stage \u2014 but they differ in torque range, frame count, brand compatibility, and the primary industries they serve. Choosing the wrong series means either oversizing, paying for brand cross-reference compatibility you don’t need, or ordering a unit that cannot be adapted to your mounting interface. This guide explains the key differences between EP300R and NB300R and gives you the criteria to make the correct selection in under five minutes.<\/p>\n<\/div>\n Before identifying the differences, it is useful to establish what the EP300R and NB300R share. Both are right angle planetary gearboxes \u2014 meaning the input (motor connection) and output shaft are positioned at 90\u00b0 to each other via an integrated spiral bevel gear stage. Both use modular construction with standard input adaptor flanges for hydraulic motors, IEC electric motors, and NEMA electric motors. Both are available with foot mount and flange mount output configurations, and with multiple output shaft types (keyed solid, splined, hollow with shrink disc).<\/p>\n Both series are manufactured and 100% load-tested at our facility, with signed test certificates shipping with every unit. IP65 sealing is standard on both series for outdoor and agricultural applications.<\/p>\nWhat Both Series Have in Common<\/h2>\n
