S1289Z-048A120C is a differential end gear with 120 teeth, made of 2024 aluminum anodized before hobbing, featuring a 48 pitch, 20° pressure angle, 1-1/8 inch bore, and 3/16 inch face width. Its pitch diameter is 2.5000 inches and outside diameter is 2.5417 inches. The gear is designed to be assembled free of charge with ordered differentials.
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.
