SERVO TO SHAFT

COUPLERS

ServoCity is now offering both a 24- tooth (C1) spline and a 25-tooth (3F/H25T) spline servo to shaft clamping couplers for $4.99. These patented servo to shaft couplers offer a simple and solid way to attach a shaft in-line with the output spline of a servo.

CASCADING X-RAIL

SLIDE KIT

Also available from ServoCity is their cascading X-Rail slide kit for $119.99. This kit provides the mechanical pieces necessary to build a winch-driven extendable arm. Fasten a motor or HS-785HB servo to the first stage of the slide kit and spool up the provided synthetic cable to get up to 34. 5" of arm extension.

The cascading X-Rail slide kit uses bearings throughout; each stage is supported by standard V-Wheels that lock into the chamfered guides of the X-Rail. The synthetic cable is routed over ultra smooth V-bearings so the torque provided by the servo or motor can be transformed into linear thrust rather than lost due to friction. The arm at full extension is rated for a 2 lb load; this makes it ideal for adding a gripper or grapple hook.

1.25” WINCH

PULLEY

The 1.25" winch pulley available for $4.99 from ServoCity works well with string or heavy-duty fishing line such as their synthetic cable. The pulley is able to fasten to any hub or component with the 0.770"
