 HSR-8498HB Robot Servo
Looking for tough and versatile servos for your Hobby Robotics projects? Hitec has two families of robot servos that are among the very best available. Both families come with idler horn options.
HSR-8498HB Robot Servo (Part No. 38498S)
Specs:
Torque at 6V: 103 oz.-in.; Hold Power: 309 oz.-in.
Speed: 0.20 sec./60 degrees
Size at 6V: (depending on configuration) 40 x 20 x 47mm; 40 x 20 x 37mm; 40 x 20 x 37mm
Weight: 55 grams
Street Price: $59.95 | |

These secondary horns are positioned opposite the power output horns for sturdy bracket-mounting in arms, grippers, Robo-One androids, quadrapeds and other multi-legged mobile robots. Note below the massive torque and even greater "holding power" of these specialized robot servos.
The HSR-8498HB was originally designed for the new ROBONOVA-1 robot (the most hackable humanoid bot yet, see the Spring 2006 issue of Robot, www.botmag.com/issue2) and is a great choice for custom robot projects in which affordability and substantial torque are important. The HSR-8498HB servo uses super strong Karbonite gears that will never wear out or create sloppy gear lash. Featuring a digital amplifier and delivering 309oz/in of holding power, the HSR-8498HB servo can also be programmed using the HFP-10 Hitec servo programmer. The HSR-8498HB servo can be built in three different configurations using the custom accessories included in each servo package. Build it as a standard servo design, or use the custom “idler” wheels to create solid and sturdy robot joints. The HSR-8498HB is designed to handle up to 6V only.
HSR-5995TG Robot Servo
If you are looking for extremely high torque, then consider the HSR-5995TG robot servo, which was designed to operate using 4.8V to 7.2V and has a standard size servo case. This digital programmable custom-designed robot servo provides a whopping 416.6oz./in. of torque at 7.4 volts. The servo uses Titanium gears, hardened steel gear pins and an axial brass bushing in the servo case. The HSR-5995TG features 180 degrees of rotation and a custom idler servo horn mounting bracket on the bottom of the servo to accommodate robot joint applications.

HSR-5995TG Robot Servo
(Part No. 35995S)
Specs:

Torque at 6V: 333 oz.-in.; Hold Power: 433 oz.-in.
Speed at 6V: 0.15 sec./60º
Torque at 7.4V: 416.61 oz.-in.; Hold Power: 541 oz.-in.
Speed at 7.4V: 0.12 sec./60º
Size: 40 x 20 x 37mm

This servo includes:
- Titanium Gears
- Coreless Motor
- Programmable / Digital Amplifier
- 180 degree rotation
- Hardened Steel Gear Pins
- Axial Brass Gear Pin Bearings
- High Resolution IC
- 8 “O” rings in the case
- Hitec MK gear
- Gold Plated Connectors
- Heavy Duty 22 gauge Twisted Wire leads
- 3 Custom Bracket optional parts
If you measured gear strength on a scale of 1 - 10, standard hobby servos with plastic gears would rate a 1, carbonite gears a 3 or 4, and titanium a 10. You can see that Hitec Robotics has carefully designed its two new servo lines to meet the engineering needs of discriminating robot builders.
