Ball Bearings, 681, 1x3x1 mm

These bearings are unbelievably small, like seriously, wow. Their inner diameter is only 1mm, outer is 3mm, and they're only 1mm thick. Unshielded.

Ball Bearings, R2ZZ, 1/8" x 3/8"

These double-shielded deep-groove ball bearings are made of high-strength bearing steel, and come pre-greased and ready to add smooth rotary motion to any of your DIY projects including model cars, skates, planes, robots, and much more. Their dimensions are simple to work with, since their inside diameter is 1/8", their outside is 3/8", and their thickness is 5/32". Deep-grove design allows high radial and axial loads, even at proportionally high RPMs of 5,000+

Ball Bearings, R4AZZ, 1/4" x 3/4"

These double-shielded deep-groove ball bearings are made of high-strength bearing steel, and come pre-greased and ready to add smooth rotary motion to any of your DIY projects including model cars, skates, planes, robots, and much more. Their dimensions are simple to work with, since their inside diameter is 1/4", their outside is 3/4", and their thickness is 9/32". Deep-grove design allows high radial and axial loads, even at proportionally high RPMs of 5,000+

Ball Bearings, R8ZZ 1/2" x 1 1/8"

Nice big bearings for all kinds of stuff. Fits nicely on a half inch shaft, and in a 1.125 inch hole. 5/16ths thick.

Micro DC Motor, 4x8mm, With Weight

These are some of the smallest motors of any kind available today, and are small, quiet, durable, and efficient!

Specifications are as follows, physical properties were measured and confirmed by us, electrical properties are from our supplier and are not tested.

Note: Motors are available with or without the eccentric weight that makes them shake. These motors DO have the weights, go here for motors without, or here for sealed pancake-type vibration motors.

•Rated Speed(RPM): 12,000 ±, 2,500
•Minimum Rated Torque: 2.68 g/cm
•Starting Current: 90mA
•Max Rated Current: 70mA
•1.3-3v DC
•Diameter: 4mm ± 0.1
•Length: 9mm Including Bearing Case
•Shaft Diameter: 0.7mm
•Shaft Length: 2mm ± 0.25mm
•Lead Length: 20mm
•Motor Weight: 0.5g Without Weight/Boot
•Motor Design: Brushed Coreless

Pancake Vibration Motor, 10mm x 3mm

These motors are an alternative to "conventional" vibration motors, providing more efficient vibration action in a sealed package. Not nearly as useful for other things because there is no output shaft, but much better at shaking up your projects!

•1.5-3V DC Operation
•120mA max
•Adhesive backed
