The Quality Components Ring Gear is an integral part of the steel / ductile iron GGG 60 housing. Gearing is precision shaped to AGMA12 quality grade and plasma hardened (up to 60HRC). Sizes 142 and 190 gears are honed after hardening. Sun Gear is made of high-grade case hardening steel precision hobbed and case hardened (up to 64 HRC). All gears sizes are precision honed resulting in quality levels of AGMA 12. Planet Gears use same material and manufacturing process as the sun gear. Bore hardened (up to 64 HRC) and precision ground to ensure an optimal run and life for the needle roller bearings Gear Honing for highest Quality
The Quality Components Output Shaft, integral one piece with the Planet Carrier is made of steel / ductile iron GGG 60. Large diameter shaft provides an increased stiffness and high strength. Output Bearing is a paired set of large angular contact Bearings. It is designed for 20 000 Hrs L10 (B10) life. It runs backlash free and can carry very high radial and axial loads Special Hardened Nut design, to retain and adjust the bearings. Its hardened and plunge ground surface is optimal for the output seal lips to run on. Housing has a square shaped integrated flange with a precision male type centering for easy mounting to the driven Machinery The Quality Components Planet Carrier integral piece with output shaft, made of GGG 60 ductile iron. It holds the bearing steel precision ground hardened planet pins, for the full packed needle roller bearings Input Bearing to secure a smooth and true run independent of the motor bearings Split Clamping Ring is made of steel (not aluminum) to allow high bolt pre-tension for high clamping forces. Applying precision bushings a mounting to a wide variety of motor shaft diameters is accomplished. Input Flange is made of aluminum. Its universal design allows to add simple flange adaptors to match the vast majority of motor flange designs.

The The Rated Rated Torque Torque is is ratio ratio dependant!! Example: A 10:1 10:1 ratio ratio planetary gear gear in in a single single stage stage must must have have a quite quite small small sun sun gear. gear.
