Slot.It 18mm sidewinder spur gears (ergal) are used for sidewinder motor setups where the motor shaft is parallel (or nearly so) to the rear axle. "Ergal" is a trade name for 7075 aluminum alloy. This sidewinder spur gear has 34 teeth (34T).
Selecting a pinion gear to mesh properly with Slot.It 18mm sidewinder spur gears will depend on the motor mount you plan to use. For for information about compatible pinions for various Slot.It motor mounts and available gear ratios, please click the link below.
- We recommend a Slot.It or Sloting Plus 3/32" solid axle (see "Related Products" below).
- While not required, we recommend applying a VERY THIN layer of grease on the pinion gear and sidewinder gear teeth. Our Super Lube Grease with PTFE (see "Related Products" below) is an excellent lubricant for this purpose.
- Slot.It sidewinder spur gears are secured to the axle using an M2x3mm set screw that is included. You will need a .9mm hex driver to install/remove the set screw (see "Related Products" below). Use care not to overtighten the set screw as you can strip the threads in the sidewinder spur gear. Replacement M2 set screws are available in the "Related Products" section below - it's a good idea to have some spares on your bench and/or in your pit box.
Package contains one (1) sidewinder spur gear.
