• This bearing block can be used as a motor mount for 16mm gearmotors (such as our Spark motors) or as a simple bearing block for a 3mm shaft.
• The bearing works with the Spark Motors by aligning the mounting holes to the Spark mounting holes and offers additional shaft support.

These anodized aluminum motor mounts will fit just about any small motor with mounting hole distances from 10mm - 12.5mm (0.39 - 0.49in).  Especially suited to both Gold and Silver Spark motors, they will also hold all "Mini Metal Gearmotors", small Copal motors, Maxon motors, etc.

• Seven different mounting slots will fit up to 3mm or 4-40 sized screws.
• Width: 16mm (0.63in)
• Height: 19.8mm (0.78in)
• Length: 18.6mm (0.73in)
• Thickness: 1.45mm (0.057in)
• Shaft height: A motor with 11mm hole spacing will raise the motor shaft up to 11.7mm (0.46in).
• Only 1.5grams (0.05oz) each!

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 torque limits listed below, 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.
• 9 different gear ratios for a wide range of rpm and torque to choose from (see details).
• Only 28grams (0.99oz).

The new 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.
• 9 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)

• Standard-sized servo.
• Metal gears for super high torque.
• 18kg-cm (250oz-in) @ 9V
• Only 56grams (1.98oz).

• Heavy Duty Aluminum Servo Saver
• Includes inserts for Futaba, Hitec, and JR servo splines.
• Don't let your servo's gears take all the force!  Protect them with a servo saver.

• One pair of 3mm ID chrome steel double-sealed ball bearings.
• If you robot has to take a lot of abuse - landing hard on the wheels, etc - these 3mm ball bearings are perfect for distributing the force into the frame.
• Made to fit the shaft of Spark motors, or any other motor with a 3mm shaft.

• Includes two 2-56 Button Head Screws (length of 1/8", 3/16" or 1/4")
• Black Oxide screws are harder than Stainless Steel or Zinc Plated and the heads will not strip out as easily.
• Use for mounting Gold Spark and Silver Spark motors.
• These screws require a 0.050" hex wrench
