Wheel Collars for RC Planes
Wheel collars lock onto an axle to hold a wheel in place and set its position, and this category covers collars and retainers in the shaft sizes common to model aircraft landing gear. A pair of collars on either side of a wheel keeps it centered and free to spin without sliding along the axle.
Sizes and Set-Screw Collars
Du-Bro wheel collars are offered across a range of bores, from 1/16 inch micro collars for small park flyers up to 1/8 inch and 5/32 inch sizes for larger models. The 5/32 inch nickel plated brass Dura-Collar adds a plated finish, and most set-screw collars let you reposition the wheel as needed.
Press-On Retainers
The RRC press-on wheel retainers come as a set of eight in two sizes, offering a quick push-fit option for light wheels where a threaded collar is not required.
