Mobilize a robot chassis with the Actobotics 4” omni wheel
available from ServoCity. Omni
wheels can be used just like regular
drive wheels but have the advantage
of being able to roll freely
perpendicular to the drive direction.
The 10 rubber rollers around the
circumference of the wheel provide
excellent grip to excel in moving in
the forward direction. Each roller is
mounted on a stainless steel sleeve
which rests on a stainless steel axle to
allow the rollers to rotate freely and
independently from one another.
Multiple wheels can be mounted
together by installing an 1/8” spacer
between the wheels to provide
adequate clearance between rollers.
The wheels can be clocked so
that the rollers are staggered evenly
which smooths out the
circumference and increases load-bearing capabilities. The wheels have
a 1/2” center hole, and numerous
mounting options are provided
including the standard 0.77” and
1.50” hub patterns for using with
other Actobotics parts.
These wheels can reduce the
amount of torque necessary to turn
while decreasing the turning radius of
your chassis. Price is $9.99.
This wheel adapter is intended to be used with ServoCity’s five
spoke pneumatic tire/wheel. This
piece is machined to perfectly mate
with the interior shape of the molded
wheel so that the adapter and the
wheel will turn as one.
The adapter houses a 1/2" ID
ball bearing so that the assembly can
be slid onto a fixed shaft and rotate
freely on that shaft. The 1.5"
Actobotics hub pattern is machined
into the adapter so that a sprocket or
gear can easily be attached to the
outside of the adapter to drive the
A single wheel adapter can be
used and the other side of the wheel
can be supported by one of the stock
bearings included with the pneumatic
tire/wheel or an adapter on each side
can be utilized for a more
ServoCity recommends running a
1/2" shaft spacer next to the bearing
installed into the adapter in order to
provide proper clearance between
the bearing and the surface that it's
running next to. Price is $15.99.
This next wheel adapter from ServoCity is also intended to be
used with their five spoke pneumatic
tire/wheel. This piece is machined to
perfectly mate with the interior shape
of the molded wheel so the adapter
and the wheel turn as one.
This adapter has the large 1.5"
hub pattern with 1/4" thru-holes
machined into the face so that
ServoCity’s 1" HD clamping hub can
be attached using 1/4-20 low profile
socket head screws.
By installing a clamping hub onto
the adapter, the wheel assembly can
be secured onto a 1" shaft. This style
adapter is commonly used in
conjunction with an axle that is
mounted in bearings so that the axle
and wheel can rotate in unison. Price
