Slot.it Aluminum Hub Lock Ring (Stopper) for MODULAR Gear & 5.5mm Pinion
New system that reduces wear by friction. Crown designed for exclusive use with offset motor mounts. This is based on the use of an independent centering device and washers that rotate freely and are located on both sides of the motor shaft. Made with aluminium and plastic of great strength and quality. Includes crown and three washers.
Requires the use of a lock ring (stopper) sold separately references SIGMF55 (for 5.5mm pinions) and SIGMF60 (for 6mm pinions).
The new M crowns are composed by three basic pieces:
1. The gear side: the gears are exactly the same as the usual Slot.it crowns, with a new insert. The insert has a non threaded hole.
2. The stopper: this is the part that keeps the shaft in place. To be combined with SIGMF55 (if 5.5mm pinion is used) or SIGMF60 (if 6mm pinion is used) sold separately.
3. The steel washers: they works as a bearing, free to rotate independently from each other and from the mutual movement of the crown and the shaft, nicely floating on a layer of oil.
