Standard gear ratios range from 4.3 to 273; F\/R combinations can reach a maximum ratio of 18,509. Both solid-shaft and hollow-shaft outputs are available. Average efficiency is approximately 96% for two-stage units and 94% for three-stage units.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">F Series Model Configurations<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Configurations include the F type with solid-shaft output for coupling connection, the shaft-mounted FA type, the flange-mounted FF type and the flange-mounted hollow-shaft FAF type. The basic model range comprises ten frame sizes from F37 to F157. Mounting options include foot mounting, hollow-shaft mounting, flange mounting, torque-arm mounting and small-flange mounting.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">Selected F Series Mounting Dimensions<\/h1>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><td><strong>Model<\/strong><\/td><td><strong>Output shaft diameter d (mm)<\/strong><\/td><td><strong>Mounting hole specification<\/strong><\/td><\/tr><\/thead><tbody><tr><td>F37<\/td><td>25k6<\/td><td>\u2013<\/td><\/tr><tr><td>F47<\/td><td>30k6<\/td><td>\u2013<\/td><\/tr><tr><td>F57<\/td><td>40k6<\/td><td>M12<\/td><\/tr><tr><td>F67<\/td><td>40k6<\/td><td>M16<\/td><\/tr><tr><td>F77<\/td><td>50k6<\/td><td>M16<\/td><\/tr><tr><td>F87<\/td><td>60m6<\/td><td>M16<\/td><\/tr><tr><td>F97<\/td><td>70m6<\/td><td>M20<\/td><\/tr><tr><td>F107<\/td><td>90m6<\/td><td>M24<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h1 class=\"wp-block-heading\">Selection Advantages of the Parallel-Shaft Layout<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Parallel-shaft gear reducers offer simpler construction than bevel gear reducers. They do not have a bevel gear stage and its associated axial force arrangement, allowing a simpler bearing configuration. This does not mean that helical gearing is free of axial thrust. Transmission efficiency is high, with standalone unit efficiency reaching 95% or above. A range of mounting arrangements provides installation flexibility.<\/p>\n\n\n\n<h1 class=\"wp-block-heading\">F Series Selection Support<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">Visit www.sanyoogear.com and submit the equipment type, load characteristics, required speed and torque, and installation conditions.
