The model number 7708833-VB identifies this Electra Gear planetary configuration. In a planetary arrangement, a central sun gear meshes with surrounding planet gears and a ring gear to achieve reduction within a small envelope. The 20:1 ratio specifies the input-to-output speed relationship for this unit, indicating how input speed is reduced at the output. Planetary gearboxes are designed to provide high torque in a compact footprint by distributing load across multiple gears within a sealed or enclosed train, which helps maintain alignment and smooth operation in constrained spaces. These gearboxes are widely used in robotics, automation, and precision machinery because their gear train design enables compact size and predictable torque transfer relative to input speed. Because multiple planet gears share the load, planetary gearboxes can offer relatively smooth operation and quieter performance in a smaller envelope compared to traditional spur gear sets. Output shaft options, input shaft alignment, and mounting configurations vary by model across the Electra Gear lineup.\u003c\/p\u003e\u003c\/div\u003e","brand":"Electra","offers":[{"title":"New","offer_id":51685664588078,"sku":null,"price":725.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_53cfe6e0-e2f4-4158-8061-d6244517f909.jpg?v=1769725907","url":"https:\/\/plgautomation.com\/products\/electra-gear-7708833-vb-planetary-gearbox","provider":"PLG Automation ","version":"1.0","type":"link"}
