FEETECH Standard Servo FS5103B
The FS5103B is a general-purpose, low-cost standard analog servo from FEETECH. Two ball bearings help reduce friction and improve performance. Servo horns and associated hardware are included. This servo can work with both 5 V and 3.3 V servo signals.
Key specs at 6 V: 0.16 sec/60°, 53 oz-in (3.8 kg-cm), 40 g.

The FS5103B is a general-purpose standard-size analog servo from FEETECH. The output shaft is supported by two ball bearings for reduced friction. The FS5103B works with standard RC servo pulses, providing a running angle of approximately 180° over a servo pulse range of 600 µs to 2400 µs, and it has a 12″ (30 cm) cable that is terminated with a standard JR-style connector, which is Futaba-compatible. You can find more information about this servo in its datasheet (133k pdf).
For more advanced robotics applications, please note that we also carry a version of this servo that is specially modified to provide access to the feedback potentiometer through a fourth (green) wire, which lets you monitor the actual position of the servo from your controller:

An aluminum servo horn that works with this servo is available separately:

Compatibility warning: In November 2018 FEETECH changed the case of this servo, making it no longer compatible with our Mounting Bracket for Standard-Size Servos. They will be switching back to the original case style, which will resolve this problem for future batches, but at this time this servo might not work properly with our mounting bracket.The modification changed the location of the wires coming out of the servo, so the bracket would no longer fit. It is possible to permanently modify the bracket to work by cutting a notch out of it with a rotary tool or a pair of diagonal cutters, but do so at your own risk as it could damage the bracket.
Note that, as with most hobby servos, stalling or back-driving this servo can damage it.
Comparison to the Power HD 3001HB servo
This servo is a lower-cost alternative to the 3001HB from Power HD, which has nearly identical dimensions and similar performance. The two servos should be generally interchangeable for most applications. The picture below shows both the FS5103B and the 3001HB side by side:
