About 90 Degree Bevel Gears
90 Degree Bevel Gears are awesome parts that help pass energy between two rods that connect at a corner, making a 90-degree angle. You can find them in lots of things—like cars, planes, huge machines, and even robots—because they’re really good at sending energy in small, careful twists. These gears are shaped like cones and have different kinds of teeth: straight ones, curly spiral ones, or a special type called zerol. That means they can work for easy, slow tasks or fast, tough ones, which makes them super helpful for building things today.
At FMP Company, we can making all sorts of 90 Degree Bevel Gears, like the straight kind, the spiral kind, and even sets that come in boxes, all made really strong and well. We can also make them just the way you like, with the perfect number of teeth, the right stuff (like metal or plastic), and the size you need. If you don’t see the gear you want on our list, don’t worry—it just means we haven’t added it yet. Just send us an email telling us what you need, and our engineers will reply in 24 hours with a great solution for your project!

Features of 90 Degree Bevel Gears
90 Degree Bevel Gears are special gears shaped like cones that move power between two shafts that meet at a 90-degree angle, like a corner. You can find them in cars, planes, and machines. There are two main kinds: straight bevel gears have simple, straight teeth and work well for slower things, like in printing machines, but they can’t be polished after being made tough with heat. Spiral bevel gears have curvy teeth that twist, making them quieter and better for fast or heavy jobs, like in car engines. They can be polished to be super exact. These gears can be made from strong stuff like steel or even plastic. Spiral gears are trickier to make but are tougher and becoming more popular because they’re so good at their job!
