No more loosening shafts.

I use these with silver sparks, gold sparks, and N20 micro gear motors. Not only are these great for taking stress off of motor shafts, but are fantastic when used for structural support.
Essential for antweights

After I switched to bearing blocks for mounting my Silver Sparks, I have not lost a single gearbox after fighting some of the nastiest spinners on the east coast. Glad I made the change.
Solid mount

These add so much strength and are so easy to add to the 3mm shaft on the Silver spark motors
Will save your motors!
- 06th September 2014
Ever since I started using these bearing blocks, my silversparks have not broken. My ant hit the 4 foot roof of an arena, landed right on the wheels, and the drive motors were fine.
Definitely the best choice for motor mounts
Great Mounts. Saves lots of time
- 22nd August 2013
These mounts are well worth the time they save in fabricating an antweight. The bearing helps remove support the motor. Some of the threads needed cleaning up a bit with a 4/40 tap. Quality is otherwise very good.
FingerTech "Gold Spark" 16mm Gearmotor

FingerTech's Gold Spark motors are great for hobby use and in competition robots such as mini-sumo and line following.  If your application will be close to or exceeding the specified torque limits (like in combat robots), check out our Silver Spark motors.

• The extra-long 3mm shaft is triple-supported internally so that wheels can be mounted directly.
• All-metal spur gear reduction gearhead mated to a Mabuchi FK-050 motor.
• 8 different gear ratios for a wide range of rpm and torque to choose from (see details).
• Only 28grams (0.99oz).
 

FingerTech "Silver Spark" 16mm Gearmotor

The Silver Spark line of motors has the same 16mm diameter as the Gold Sparks, but the gears are a larger pitch. This means less worrying about stripping teeth in your bigger or heavier applications!


• Extra-long 3mm shaft for mounting wheels directly with the option to use a bearing block for support on the wheel's far side.

• Same 11mm face mount pattern as Gold Spark motors.

• All-metal spur gearhead mated to a Mabuchi FK-050 motor.

• 8 different gear ratios for a wide range of rpm and torque to choose from.  One twice as fast, and one twice as slow as the Gold Sparks!

• Weights from 28 - 32grams (0.99 - 1.13oz). (see details)
