Horizontal gears with upward-pointing teeth, known as face gears, do exist but are less common than conical gears due to their efficiency. While they can be custom manufactured, they are not readily available on major gear supply websites like SDP-SI or Boston Gear. Alternatives such as bevel gears or ring and pinion systems may be more practical for certain applications. The discussion highlights the niche use of face gears and the challenges in sourcing them. Custom manufacturing is likely necessary for those seeking face gears.
