Wheel collars lock onto an axle to keep a wheel in place, setting its side-to-side position and stopping it from sliding off in use. A set of collars is one of those small hardware items nearly every builder keeps on hand, since axle diameters vary from one model to the next and a lost collar can ground an airplane.
Du-Bro Wheel Collars
The Du-Bro range spans common shaft sizes, including 1/16 inch (1.5mm), 3/32 inch (2.3mm), 1/8 inch, and 5/32 inch, with nickel plated and Dura-Collar options. A matching collar clamps to the axle with a set screw for a secure hold, and the micro sizes suit the fine wire axles found on small electric models.
Press-On Retainers
Where a lighter, tool-free approach suits a small model, the RRC Press On Wheel Retainers arrive as a set of eight in two sizes, pressing directly onto the axle to hold the wheel without a screw.
Match a collar or retainer to your axle size in the list below.
