The Toughbox Micro offers the same gear ratios as the Toughbox Mini in a smaller footprint and gives easy access for repairs or maintenance. This gearbox features a lightweight, durable plastic molded housing and has two different shaft plate options for endless mounting and usage options. The Toughbox Micro accepts one CIM motor and is perfect for drivetrain and mechanism uses.
All AndyMark gearboxes require grease for proper operation and long life. We suggest using our Red Tacky Grease (am-2768). We also encourage that the user powers the gearbox continuously for 30 minutes without grease to allow the gear teeth to wear in. While we do design with short run times in mind, we highly recommend this 'run in' period for smooth gearbox operation. Once this is completed, thoroughly grease the gear teeth periodically to ensure smooth operation.
The best solution for encoders on these gearboxes is the SRX Magnetic Encoder (am-3445). The output shafts include a built in magnet to work with this encoder. Use the SRX Magnetic Encoder Mounting Hardware Kit (am-3565) in conjunction with the SRX Magnetic Encoder for a perfect fit.

Updated Toughbox Gearbox
Our FIRST Robotics Competition has used the Toughbox Nano for several years without failure. As the Nano is outdated and replaced by the Micro, we find similar performance and expect similar durability. The new design saves a bit of weight and fits exactly in place of the previous version. The gearbox held up in practice sessions and we anticipate completing competition season without failure.
