Actobotics’ new pattern plates are identical to a single side of the Actobotics channel
(hyperlink to channel). These plates are an
excellent addition to an extensive building
system as they allow you to box in your
channel for added strength; build in space-limited areas; and save weight and cost
where the strength of a full piece of
channel is not a necessity. Pricing
ranges from $1.39-$3.99.
ServoCity’s clamping D-hubs are a noteworthy solution for transferring power from a shaft to a hub. While
conventional clamping hubs with a cylindrical bore rely
solely on clamping force to keep the hub from slipping on
the shaft, these new D-hubs have a D-shaped bore to
perfectly match a D-shaft of the same diameter.
This means that even without tightening the pinch
bolt, the hub is prevented from slipping on the shaft. The
6-32 pinch bolt (when tightened)
will tighten the hub around the D-shaft for added security, and to
keep the D-hub from sliding up
and down the shaft. Price is $6.99.
New set screw D-hubs from ServoCity also offer a solution for transferring power from a shaft
to the hub. While conventional hubs with a cylindrical
bore rely solely on the set screw to keep the hub from
slipping on the shaft, the new D-hubs have a D-shaped
bore to perfectly match a D-shaft of the same diameter.
This means that even without a set-screw, the hub is
prevented from slipping on the shaft.
The 10-32 set-screw, when tightened, will apply
pressure to the flat of the D-shaft for added security and
to keep the D-hub from sliding up and down the shaft.
Since the set screw contacts the flat of the shaft, it makes
removal of the hub very easy — no marring of the
cylindrical surface which would interfere with the
installation/removal of parts such as ball bearings. Price is
