The revolutionary inline crown gear couples, for the first time in slot racing, a grub screw together with the common 'self centering crown gear' where the motor axle is inserted in a thread in the crown itself. The shape of the gears and the polymer compound have been optimized through several months of research and many years of competitions, and offer unparalleled reliability, smoothness and efficiency. The threaded insert can be Bronze, tested in many successful 24 hrs endurance competitions, or Aluminium for best performance in sprint races. For sidewinder chassis Slot.it offers 6 different spur gears, with either 18mm or 19mm gear diameter, made in anodized Ergal with the same technology of the famous Slot.it pinions: different gear count with the same external diameter, enabling the racer to change gear ratio in a way which was previously impossible.
8 new Step2 inline crown gears with new plastic materials, new revolutionary tooth shape, new aluminium insert with anti-friction treatment: the ‘Step 2’ Slot.it inline crowns have further enhanced the performance and durability of the already best-in-class Slot.it gears.
5 angled spur gears with asymmetric tooth, a world first, in Ergal.
6 sidewinder spur gears, with either 18mm or 19mm gear diameter, made in anodized Ergal with the same technology of the famous Slot.it pinions: different gear count with the same external diameter, enabling the racer to change gear ratio in a way which was previously impossible.
Inline crowns, set screw, self centering with the motor pinion
The ProAxle inline crowns are an innovation for slot racers. These extremely
high mechanical precision couple show a unique feature: the set hexagonal
screw locking is coupled, for the first time in slot racing, to
the self centering thread where the motor axle is inserted, like in all
modern Euro 1/32 slot cars (patent pending). The self lubricating polimer
that makes up the crown guarantees maximum smoothness together with the
optimal gear shape, optimized in several months research. The threaded
insert is in bronze (for all uses) ar aluminium (for extremely high performance
racing - it is mandatory to lube the thread before every usage and with
regularity), and the low tolerance of the thread keeps the pinion and
the gear at the optimal gearing distance. Perfect with Slot.it pinions
and with the pinions that are normally used on cars out of the box (we
recommend using brass pinions)
Spur gears, ERGAL
ProAxle Sidewinder crowns, made in anodized ERGAL (Aluminium alloy with
steel-like mechanical performance, with which the motorcycles crowns
are often made) are the perfect solution for sidewinder cars. Built with
the same technology of the famous Slot.it pinions, all three spur gears
(SIGI01/02/03 and 04/05/06) have the same external diameter, making
it possible to change gear ratio without moving the motor, which so far
has not been possible on plastic cars. You must see how they mesh
with our pinions, to believe it! We recommend using brass pinions.
