reducer is a Speed Reducers product. Key specs — Brand: yinyu; Origin: China (Mainland).
Product Description
High reduction ratios, without sacrificing efficiency. Compact designs, without requiring special motors. Exceptional shock load capacity, without having to oversize. Greater overhung load capacities, without using expensive special components. A precision backlash option, without resorting to special gearing.   FEATURE
BENEFITS
High Efficiency Cycloidal Reducer Design
Single stage reduction ratios up to 71:1 saves space Rolling motion minimizes friction and wear, reducing heat, resulting in a 95% efficiency rating per stage 500% shock load capability as there are only compressive forces rather than shear forces on the tooth Low speed of cycloidal wheel results in minimal reflected inertia less wear, and extremely long service life Due to the large overall “tooth / pin” contact area, select a Reducer using smaller mechanical service factors
Two Backlash Ratings
Standard backlash offers the highest available torque rating at an economical price Precision backlash results in tighter positional tolerances
Multiple Inputs: NEMA C-Face, Servo Square Flange, Shaft Input, Shovel Base, Top Mount
Versatility to fit whatever prime mover is needed for the application NEMA and servo input flanges are compact “quill-style” hollowbore configuration, eliminating input couplings and guards Quill-style input features an input support bearing to control fretting corrosion between motor shaft and reducer hub, and permit tighter internal tolerances NEMA input flange includes threaded back-off holes for easy motor removal
Straddle Mount Output Shaft Bearings (sizes D, E, F)
Supports output shaft and drive pins to provide exceptional overhung and thrust load capability, without the need for special bearings or housings
Multiple Mounting Options: Base, Flange, Ring
Versatility to fit anywhere on your machine Ring style allows output bearing to extend well within the machine for greatest overhung load rating
