3mm Sealed Ball Bearings (2)

(Enlarge)

Description

Supporting a motor shaft with a bearing on the opposite side greatly increases the loads the motor can support. (Bearing blocks not included.)

Size: 3mm ID x 6mm OD x 2.5mm width
Weight: 0.5 grams each
Double shielded for extended life.
Chrome steel construction.

Don't have a 6mm drill bit? You can use a 7/32" bit and ream the hole out slightly to press a bearing in.

great quality

Evan Steeves - 21st May 2011

Bought 4 of these for external mounts on the spark gold motors and have used them for months on an antweight pusher with no problems!

Good

	FingerTech "Gold Spark" 16mm Gearmotor - 19.05 CAD
	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).
	FingerTech "Silver Spark" 16mm Gearmotor - 23.81 CAD
	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)
