Hypoid spiral bevel gearboxes right angle and offset. A hypoid pinion is offset from the gear centre which gives this a stronger pinion than a comparable spiral bevel design. Hypoid gearboxes from Ondrives are finish hardened and ground to give excellent characteristics in smooth quiet motion.
The HYSB (Small Offset Medium Ratios) Hypoid bevel gear versions have small offsets and ratios 3:1 to 15:1. The HRHC (High Ratio High Offset) SRH HRH Hypoid gears have large offsets and high ratios 10:1 to 60:1. The SBC (Right Angle Inline Low Ratios) Spiral Bevels right angle inline ratios 1:1 to 5:1.
