The S1289Z-048A090C is a 48-pitch differential end gear made of 2024 aluminum, anodized before hobbing, with 90 teeth, a pitch diameter of 1.8750 inches, and an outer diameter of 1.9167 inches. It has a 1-1/8 inch bore and a 20° pressure angle. The gear is designed for assembly with differentials ordered at the same time and features a 3/16 inch face width.
In a standard differential, two output shafts distribute a load imparted on them from an input shaft at different speeds. A differential contains a pinion (bevel) gear [A] on the input shaft, where the load is transmitted. The pinion mates with a [B] carrier or ring (bevel) gear at 90°. Mounted to the carrier gear are two symmetrically placed spider (bevel) gears at 180° (this is to prevent bending stresses in the output shafts). [C] The spider gears spin on their own axes and along the carrier gear. They mesh with two gears on either side, connected to the output shafts [D].
SDP/SI offers differentials with hollow and solid shafts and anti-backlash properties.
